    I have a 2006 Sport , and finally got to go on some serious 4wheel dr roads here in Colorado. Going down a steep incline in 4L L, when I engaged the Downhill assist it was effective, however there was a rubbing, grinding (mild) noise that made me a little nervous. Has anyone experienced this? It wasn't extreme, and may be normal, but it was a "noise" .

    I just bought a new 2008 4Runner and spent a few hours reading through all of the owner's manuals and guides. Pretty sure I saw something that said there would be a little noise emanating from the DAC. Perhaps you can check your operating manual and see if you can find what I think I found.

    my toyota has 48K miles on it. about 6 months ago I noticed a slight muffled pinging in the engine-mostly when going slow or in city traffic--its grown into a large deep ping-sounds more like a hole in a muffler than an engine problem--but its coming from the engine. I just took it to the dealer--they called and said I put too much oil in it--that isnt so-I have it serviced religiously and just checked the oil 2 days ago--they went on to say it was going to cost 5K to fix-but didnt tell me what the problem is--except said there is too much oil in the crankshaft. Anyone ever heard of the noise I am having with the car??other than the noise it drives great and I love the car? Suggestions? advice?
  • Rather hard to diagnosis over the net but it from your description, it sounds like a bearing noise. Does it happen when accelerating, under load?
    Too much oil will cause "foaming" and if left that way for a period of time, it will cause bearing failure.
    Dealer didn't tell you what the problem is and said it's going to cost $5,000?
    Get a second opinion from another shop, preferably a local shop.
    Let us know.....

    Downhill assist uses the anti-lock brakes to control the speed. I suspect that is what you were hearing and feeling.
  • usually from a stopped position when i accelerate as imake a right turn , i hear a lound noise as if i am bottoming out?
  • Almost a year now, I have been hearing this noise like water boiling in kettle and occasionally twig braking sounds coming from under the glove compartment. There were also water leaks on the passenger side mat on few occaions. I take my car services to Toyata and they claimed they checked and found no problems and for the water leaks they said they drained the AC water hose and should not recur. For the noises they said they have not heard any. I hear the noises when I start the car and for the first few minutes while driving but then it fades away. Please help why is this happening

    Thank you
  • I have a 2001 toyota 4runner w/ 76K miles. No accidents or issues. The help I need is that:

    I have a "clunking" metal noise that I can re-create occur when I make a hard turn to the left. My CV boots are intact. My steering is excellent at any speed.
    No vibrations in the steering wheel at any mileage.

    Important note: this is the model year which there is a front left BALL JOINT issue from time of the manufacter. I am not sure if it was repaired.

    Important note also: the noise does not seem to occur at temperatures below 35 degree's here in Colorado. ( i.e., expansion and contraction of metal parts)

    I recently had my shocks and springs changed.

    I do see worn bushings on the front control arm and stabilizer bars ! Coulod this be the problem? What is the best way to isolate the issue?

  • For the water boil/leak on passenger side-

    Definitely a heater core leak. The engine coolant is routed through the radiator to cool it down. Someone figured out that if you routed it through a miniature radiator and blew air through that into the compartment, it would make a good heater while helping to cool the coolant down.

    Now, the coolant system is under pressure. If a small leak occurs in the heater core (which happens from time to time as they are usually metal and will corrode) then the pressure/temperature combination will cause the coolant in there to boil, and it will leak out as steam which will condense and leak in the compartment. The AC has nothing to do with it.

    If you are interested-
    With the hood up, you should see a big round cylinder at the passenger side of the firewall (that which separates the hood area from the interior.) This is the cover for the blower motor. The fan for the blower motor is accessible from then inside of the passenger compartment behind the glove box. That is the air side of this. The heater core is wedged up in there pretty close to it all. If you look again in the hood area to the blower motor housing, you will see two (approximately 5/8") rubber coolant hoses. Likely one is running to the radiator and the other into the engine block. They are big, rubber, spongy and flexible, unlike the AC lines which are ridgid and metal. What those two hoses are clamped to near the blower motor housing/firewall is the heater core that is leaking an needs to be replaced. I'd check those hoses where they connect to the core first, just in case that is the trouble.

    The heater core is usually replaced by removing the glove-box, the blower fan, and a few screws, then disconnecting those hoses (while the engine is cool and has been off for a long while. It never hurts to have the negative battery terminal disconnected either.) Then it can be pulled out. Its about 6" x 8" x 1" or thereabouts. A refurbished unit should run about 100 dollars or less, and a decent mechanic should be able to knock the job out in an hour or so.

    Hope that helps... Merry Christmas.
  • Hey I had that problems before. Below freezing the front left would make noise, now my front right makes noise. Wheel speed related??

    I greased up where my half shaft goes through the hub and problem solved. Now I have to do it on the other side. There is also a bearing replacesment from toyota for it if yours are no good, mine where still going strong at 300kms.

    Front Hub Spindle bearing.
  • ok i have this humming or grinding noise when ever the t4r is in motion. im pretty sure its the driveshaft. first of all i started to
    1.hear the noise
    2.whenever the truck is in motion ill let it coast and shut it off and noise would still be there. when in park i brought the rpm's up, there was no noise.
    so this eliminates the motor

    3. i checked wheel bearings by jacking up my t4r and tried to move wheel to see if there was any freeplay or slop there was none.

    4. i then greased the brake pads.

    5. i then took it out for a test drive.
    6. still the same
    7. i greased the ujoints and took it for a drive. 8.still the same.
    9.then i greased the driveshaft its that slip yoke type and it got worse.
    so could this mean i got a bad driveshaft?

    and i also added diff gear oil.

    did anyone have the same problem?

    I own a 06 Tacoma already has 92,000 miles on it and has the same problem i been told that the differential have to be replace it wore down. and if you ask at a dealer they will ask a lot for the part, better going to a 3rd party research the prices before you buy it get the one with the best deal on it.
  • I have a 1997 4 runner with a front diff leak, I am wondering what could be the cause and the repair and where is a good place to take it ? I moved here from vegas so dont have a local auto guy,

  • i seem to have the same problem---did you ever find out the problem?
  • I think I've got the same problem. Did you ever diagnose and fix this? I'd really like to hear about it.

  • 2002 4runner Sr5 makes rattling noise when standing still or backing up. In park there is no noise or when I am driving. Silent airplane noise when I am accelerating. One mechanic said torque on transmission. Another the exhaust system. Help.
  • On my Toyota there is a clunking noise coming from the rear end on lateral movement. I am able to push the back end of the 4Runner with my hand and it just clunks. I think the clunk is coming from the passenger side maybe wheel bearing. Dose anyone one have any idea what the problem could be?

    Not a noise or sound, but my son recently bought an '06 4runner with an existing roof rack. Yesterday he notices that the "rubber molding" in the driver side channel was missing in between the perpendicularly place rails. The stripping is on the passenger side not the driver side.

    It must have never been replace when the rack was installed but was wondering if some type of stock molding could work in its place?

    Thanks in advance

    I've got an 07 and while waxing it I noticed that the strip you are talking about was not perfectly flat in its groove. I was able to press it back into place. I'm guessing that it was disturbed by the carwash I had just gotten. My guess is that you will have to order it from Toyota in order to get a proper fit.
