Toyota 4Runner Maintenance and Repair



  • rjordanrjordan Posts: 30
            One or more of the online automotive parts and upgrade suppliers have a remote mounted oil filter for the Toyota 4Runner V8. Someone gave instructions on how to install it, but you will have to do a search to find the message. Bob.
  • I have T100 with 3.4L engine. I believe it is the same engine on some 4runner. My truck is very noisy (high pitch rattling noise) near the firewall toward the driver side during acceleration from 2000RPM on. It is not as noisy when not under load. I found that the sheetmetal that cover the exhaust manifold from the left side of the engine to the right side is the problem. There is one part of this metal about 3-4 inched long that follow the curve of the manifold that is not supported well enough. I fixed by clamping with metal strap radiator hose clamp and the noise is completely gone. Good luck.
  • am toying with the idea of an '05 SR5 V6 4wd. One thing (among many) I am curious about is if there is any extra noise while in 4WD mode (vs regular 2wd rear drive mode). I had a '94 pathfinder XE V6 5sp and it made all types of extra noise (hard to describe... like a whoosh type sound) from the around the front transfer case area when the vehicle was put in 4wd (hi mode).
    In 2wd mode, the noise was not there.
    I know this was normal for that vehicle at the time because I drove others and noticed same thing. Also, mine had a very basic non-center differential type system meant for non-dry pavement only.

    Has anyone noticed anything like this on the '04/'05 V6 4wd 4-runners? (I believe the V8 has a different, always engaged, AWD system?) Is the vehicle just as quiet when 4wd (hi) is engaged as driving in 2wd mode? Or is it noisier like my old Pathfinder was?
  • No i have the 4.0 v6 2003 limited 4runner, but i think it is the exhaust manifold which is not insulated enough. The air coming out of the engine upon acceleration is making the rattling sound, which gets louder in the winter. I may try your idea though, it seems it might just work.

    Well, I took delivery of my 2005 SR5 V6 and really like it. I was aware of the sulfur smell from previous postings, but hoped that that problem was corrected on the 2005 model. I was sadly mistaken.

    I was driving from San Diego to the Pasadena area and detected the sulfur smell when the engine was under load, due to going up hills/mountains. I was also accelerating onto the highway up in Pasadena and my daughter remarked "what's that awful smell"? I was a little embarrassed by the sulfur smell.

    I took the 4Runner into the dealer yesterday and explained the situation to the service writer. I told him that I was aware of the sulfur smell problem with the 2003-2004 4Runner V6, and I also had the tech bulletin numbers as proof. He did say that the fix on the previous years was to adjust the computer settings for the fuel and to replace the catalytic converter(s). He checked with the service manager to see if the tech bulletin applied to the 2005s, but the manager said that there is no bulletin yet. So, they checked the fuel settings only and said that they would contact me if and when they received it. They were nice about it, but it's very frustrating to still have the condition, even though they agree that there is a problem.

    I really would have thought that Toyota would have figured out the problem and corrected it by now. If anyone has any comments on this, I'd like to hear them. I am still very happy with the vehicle, though.

    yobow1, you've probably read many of the 700+ previous messages in this thread, so I won't cover that ground again. I will offer one suggestion and ask one question, though.

    The suggestion is that when you experience the smell (or if you want to avoid doing so) you should turn the HVAC fan on at least the low position and make sure the cabin air intake is on fresh rather than recirculate (the light in the recirculate button is off).

    The question is whether you ever experience the smell again when the system is configured this way. If you're getting the smell when you change to these settings, it should go away in a minute or two and stay away as long as these settings are used (at least if you're not following someone with the same problem!) Please let us know about your experience if you try this.
  • yobow1yobow1 Posts: 29
    Thanks for the suggestion, Corancher. When I experience the sulfur smell, I have the rear hatch window down, usually about 3 inches. I also have the moon roof opened all the way or just tilted. I rarely have the recirculate on, unless I'm trying to cool the inside down fast with the AC. When the windows are closed all the way, I might have noticed a slight smell, but not much.

    I had a 2002 4Runner and did the same thing with the rear hatch window and never had a sulfur any time over the 36,000 plus miles I put on it. But, I'm still baffled why Toyota can't correct this condition before the vehicle is sold and after 2 years of production time.
  • coranchercorancher Posts: 232
    yobow1, I'm not sure if you can reliably keep the smell out when the rear window is down, but I do know of one approach to try. Whether it's for technical reasons or simply a design philosophy, Toyota has moved away from side-pointing exhausts on all the vehicles I've seen. I think that the rear-pointing exhaust is a problem for both the cabin exhaust (at least they're supposed to be exhaust) vents and for the dead air at the blunt rear end of a vehicle like this. Getting your local muffler shop to point the exhaust tip to the side may be of some help. Your 2002 probably exhausted to the side, but it also wasn't one of these extra-clean-burning new engines, so it's hard to be sure about the main cause of the problem in your case.

    As for fixing the problem by reducing or eliminating the smell at the source, the TSB may be the only thing you can do. It changes the catalysts (to ones with more nickel?) and makes changes in engine management (more fuel in some situations, to avoid letting the sulfur compounds build up?) but these are not changes that Toyota is making on all 4Runners or on newly-produced ones. Presumably there's a trade-off of some kind, though it may be small.

    corancher, thanks again for your input. We'll see how the TSB goes on the 2005s...or I may have to just bite the bullet.

    I own a 2004 4Runner SR5 V6 RWD and have currently 18k miles on it. I recently noticed an increase in mileage both on highway and in-town. I never got more than 15-16 in town and 19-20 on highway but now this ratio is 20/24 consistently for 3 full gas tanks. This is not just computer reading but i noticed it by actuall mileage and tank fill up. I am using Shell 87 octane. Though i understand gas mileage differs in winter and summer but it was surprising to me at the end of summer. During Jun-Aug my mileage was worse. The only thing i did was use Shell V Power for 1500 miles, that gave worse mileage during that and change engine oil to Valvoline Semi Synthetic. I am unable to relate these changes to my increased mileage other than the fact, that gas expands in summer giving more efficient burning, but its not peak summer in Louisiana. The other thing i can think is the Self Learning of Computer, which optimizes Air/Fuel Ratio based on your driving habbit.

    About that sulfur, I had occasional strong sulfur smell in the beginning but never noticed it again to date. I never drive with my windowns open and have kept recirculate on and off. I saw the TSB and hesitent to change CAT converter, that it might reduce my mileage.

    Any thoughts on this?

    Hello, I have the 2004 4Runner V6 4wd limited edition and it does not make any sound while shifting or after its engaged to 4wd hi mode or even when shifting back to 2wd. Before you take delivery, engage the 4wd and check for yourself. Bob.
  • I think I have the same problem you are mentioning. It seems like every so often (5 or 6 times I step on the brakes) I get a ping also. I've brought it to the Dealer, and they they could not find anything immediate to say its a problem or just part of the design. I tried the Dealer's 2003 4Runner and did not notice the ping as much. It was alot more subtle. It bothers me because I can feel it. The dealer cannot find any Toyota Bulletins in Canada or US indicating any other recorded problems. I can't seem to believe this because it seems like several other people have similar problems. Is there anything I can give my Dealer to direct him.
  • I like your answer, but it still doesn't explain to me why I feel this Ping on the pedal every so often. If everyone on this chat tells me that they feel this ping, then I would find better things to do with my time. Can anyone tell me if they do feel this on the brake pedal.

    Thanks for the explanation, but I don't think the problem is going to disappear over time.
  • Does anyone notice a Brake ping when they are applying the brakes. When driving around town or on the highway., it seems like every 5th or 6th time that I step on the brake pedal for whatever reason, I get a slight ping or buzz on the pedal.

    Try this experiment. Put your car in park, and depress the brakes a few times. It does not have to be depressed too far. At the 5th or 6th time, you'll hear a buzz from the brake area.

    The buzz doesn't bother me as much as the ping I fell in the pedal. Does anyone else feel this while they are driving around town. My dealer doesn't want to jump to conclusion as what the problem is. He says he doesn't feel it in his 2003 4 Runner.

    Anyone out there might know if this is a problem or not. I also have a 2003 Highlander. The brakes feel alot better.

    Please Help Me anyone

  • A few months ago there were some posts from owners who noticed a rattle in the area of their defroster vents near the windshield - a jiggling noise that seemed in some cases to be temperature related.
    A similar sound has developed in my vehicle - it clears itself in warm sunlight or if I run the defroster at very warm temperature on high for several minutes. But if I start out on uneven pavement or washboard road in cold weather the rattle is very noticeable across the entire span of the windshield. Apparently, the defroster hardware (vents)contracts under cold temperature and something inside loosens up.
    Do any other owners who've experienced a similar problem have a way of dampening the hardware by inserting something into the vents or spraying something that might counteract the increased play within the parts , a method that doesn't require pulling out the dash to access the defroster vents? I'd rather live with the intermittent noise than take a chance on creating a worse problem by having the dealership tinker inside the dash. Of course, if anyone has had their dealership successfully eliminate the problem by going inside the dash, I would be interested in knowing how the technician accomplished that, as well.
  • Mine is doing the same thing, but if you read your manual more carefully, you'll find that it's normal. As for the buzz, you're not supposed to depress brakes with ABS multiple times - you're confusing the computer.
  • We test drove a '04 this weekend and at one point, I noticed what you are calling a ping when we stopped. It didn't happen every time, but it certainly did on that occasion. When I got out, I looked at the breaks and noticed that the brake drums were rusted. Maybe that has something to do with it. Who knows. I'll tell you though, for it being a test drive, I was a little unnerved by the occurrence.
  • Based on reports I saw of a similar problem with Toyota's RAV4 on these boards - decided to spray base of windshield with WD-40. Worked. Rattle gone. It was the interaction of the windshield with the exterior cowling - dry and cold conditions created friction.
  • I will check my manual and see what it say about the buzz. The buzz does not bother me as much as the little ping I feel occasionally on the pedal. I only say to depress the brakes several times in the park position because I can reproduce the ping after the 6th time that I depress the pedal. Also when you drive around, you will have to brake sooner or later. After the 6th time you step on the brake, you get a ping. If you don't notice this on your 4Runner, then that makes me think it might be my car.

    There has been other people indicating that they had the Master Cylinder changed. Are they for serious?

    I have about 5000 km on the vehicle. Almost ready for the first Oil Change. Someone had suggested maybe it's rust on the drum. Not this 4Runner!

    The problem is a bit more complicated than that.

    Does anyone else feel this little ping on the brake pedal?

    Suggestions to this problem greatly appreciated. I am able to lock/unlock my truck using the keychain remote. However, recently once I get in and try to start the truck, the ignition switch has been deactivated. I can reactivate it by simply unhooking/rehooking the truck's battery, so there is a work-around. It seems something has malfunctioned w/ the alarm system. Any suggestions?
  • Hello all.
    I purchased a 95 V6 4WD in September. It's the Limited model, leather, sunroof, etc. It was in beautiful shape when I bought it, only 135,000 miles on it. Basically stole it for $5300. Anyway, it does have a couple minor things I am wondering about.
    First: When I open the rear window, the wiper arm goes inside the truck. I can't close the rear window unless I actually hold the arm out of the way. Is there some kind of rest or piece that holds the arm out of the way?
    Second: The truck has no manual. What is the "on/off" rocker switch below the gear shifters, on the drivers side next to the coin holders? I know the other one is for the rear window.
    Thanks, and this is undoubtedly THE premier 4runner forum!

    yes, there is supposed to be a little rubber platform above the rear window that the wiper goes up to and sits on. In order to accomplish this, the wiper itself has to have a little plastic extender on it that rides up onto the platform and parks the wiper in the correct spot. If either are missing, the wiper naturally will not perform properly. It is especially common for people over the years to have replaced the rear wiper blade and NOT reinstalled the plastic extender, which messes everything up. If either is missing, I am sure it would be cheap to get a replacement from the dealer.

    As to your second point, mine is a '90 and so it is different. I know they moved the buttons around on the console between '90 and '95, and yours may have an extra feature that mine doesn't have.

  • My 2003 Sport has 35,500 miles. Any suggestions on what to make sure I take care of before it rolls out of warranty?

    I took it in this morning for: 1) sunroof rattle, 2) loose sunglass holder/cabin light assembly, and 3) popping in the rear speaker (JBL system) when the volume is turned up and the engine's running (doesn't seem to do it when the engine's off).

    I'd had the sunroof rattle fixed awhile back, but afterward noticed the rubber was bunched in one spot. I took it back and they replaced the entire sunroof (!). Of course, with a new sunroof, the rattling started up again.
  • It seems that others have had problems with their Check Engine and VSC Off/Trac lights. The lights on my girlfriend's '02 4WD 4Runner came on this morning. The car was in the shop a few days ago for a tune up and alignment adjustment, but I don't know how this would cause the VSC lights to turn on. I actually took the car back to the shop, but the lights weren't on when the truck was there and they said nothing was loose from the tune up. On my way to work , the lights stayed off. The lights came back on during lunch and it stalled at a stop sign. It seems to be running fine - other than the stall - although it does seem like it has lost a bit of power.

    The car is out of basic warranty, but the drivetrain warranty is still good. Is this covered by the drivetrain warranty? If not, does it matter if I take it to an independant shop? I'll be taking the car in tomorrow for a full diagnostic, but any suggestions, recommendations or insights are greatly appreciated.

  • I have a 2001 4WD SR5 and have had the same two lights come on and stay on. After a trip to the dealer, I was informed that if both lights are lit, the computer has registered a fault code. Mine was from the gas cap not being loose and the emissions system registering a vapor leak. I would find a dealer with a good reputation and have the computer checked for error codes.
  • Well, I checked the gas cap and it was on fine. I loosened then retightened it just to make sure. The first few times I cranked the engine, it started fine, then quickly died. After a few more starts it now refuses to start at all. The engine cranks, but will not turn over. I had forgotten that we also had the transmission system flushed. Would the car refuse to start if there wasn't enough - or any - AT fluid? I noticed the ATF Temp light on while trying to start it the last few times, but it might be normal for it to just been on with the others when starting. I just wish this happened at home rather than at work (where I still am).
  • I have just purchased a 2005 V6 RWD Sport (three days ago).

    Yes, I feel the ping as well. I was quite disturbed by it too. I am planning on going to the dealer tomorrow to have them check it out.

    Do you think it has anything to do with ABS?? Maybe it is part of the design.
  • Hi All,
    I have a 2002 4Runnuer. My sense lights 'VSC Off' & 'VSC trac' are on for months now. These lights were apparently selected by on-board computer because it had to select something to display. Toyota dealer advised me to ignore the expected meaning of these lights because it really is because my gas system overflow cup was ruined by too much gas 'topping-off' at the gas stations. He also said lights would shut-off in 1000 miles. The lights are still lit. Dealer said replacing cup would cost an exorbitant amount which I don't feel like paying. Anybody else encounter this problem? TIA
  • i have been reading the posts about the moonroof vibrations and rattling, but my problem is when i am driving with my back windows down or partially down and a closed moonroof, the moonroof shakes so violently that the headrests on the seats start vibrating too. this is a 2004 limited and the problem started after the first 1000 miles. my dealer and the service tech told me not to drive with my back windows rolled down ever. i have kids riding in the back seats. it feels as if the moonroof is going to shake off, the dealer says this is normal. i feel it is a danger. does anyone else have this happening? thanks
  • I would like to add the Limited sun visor with the illuminated vanity mirror to the passenger side of my '04 Sport Edition 4Runner, and also the electrochromatic rearview mirror. I found a vendor to supply both, but can't tell how hard it would be to get power to them. Since the mirror is listed as an option for my vehicle, I think wiring for the mirror might be in place, but not for the visor. Has anyone else tried this, or have recommendations for me? I'm pretty handy, but have no clue about how to remove the headliner if that's required. Thanks!
