Toyota 4Runner Maintenance and Repair

    I definitely don't want to go the squealing route, that would drive me crazy. Why would turning the rotors result in the problem coming back in a few thousand miles? It took over 80K to get to this point.

  • ponytrekkerponytrekker Posts: 307
    they are pulsing because they are warped. They are warped, not because you drove 80k on them, but because metal when heated and then cooled quickly changes shape. This could happen in 2k miles.

    Turning the rotors scrapes a layer off them. At some point there is no more "layer" to scrape.

    Usually a turn will do it but at some point they will have to be replaced.

    OK, thanks. That makes sense. It sounds like replacing them along with the pads would result in less problems going forward.

    Thanks for everyone's help!

    I believe I would have the dealer look at this because of ABS and Electrical Sensors involved, and quite possibly brake booster. Don't gamble with this. It could be something insignifagant or a serious problem waiting to happen. Don't gamble with brakes. Ben

    I am experiencing the exact same problem with my 2000 4runner limited. Anyone have any resolution/suggestions, since I did not see a resolution in the thread? Thanks for any insight or help you might be able to provide.

    FYI, I have checked the door switches, all are traveling freely. If I manually lock all the doors (to include using the key to lock the back door), and I hit the remote lock button, it gives me the single beep saying the doors are locked. Otherwise, I cannot lock the vehicle using the remote, or either the drivers side or passenger side lock button. All methods work for unlock.

    I have a 97 toy 4runner, recently the ignition has been acting up. This is what happens. Usually when I have the key in the ignition (door open) and try to lock the doors, it won't let me (the car will not let you lock the doors). That option doesn't work anymore. Also, the light that illuminates the key whole no longer works. Also, when the lights are on and the key is in the ignition and I open the door, I would be told by buzzer that my lights are on, this audible sound no longer exists. Which one do I replace, the tumbler or the electronic part of the ignition? Thanks in advance.

  • I have a 92 Toyota 4runner and I would like to throw a 3.4 liter V6 from a tacoma in it. Would any know where I could get a conversion kit from?

    Wow, my '97 4runner passenger compartment caught on fire. Luckily we were OK, but in no time it was fully in flames, exploding, very scary! TG for the fire department. I saw your message and though it's old, just had to reply

    Please let us know what the cause was if you find out. Glad everyone is OK!

    4runner gas tank is plastic, right?
  • kpustkpust Posts: 1
    I just bought a 2007 4Runner SR5 4WD V6, 18K . Intermittantly I am getting a very heavy smell of amonia that just about knocks me out! There is sometimes also a burning smell before the amonia smell. My Mechanic cant find anything. Do any of you know what this may be? I have only had the car 1 week and it has happened numerous times. The airconditioning is not running and the windows are open when I drive. What other fluid could cause this odor? :confuse: Thanks for the help!

    Most gas tanks are light weight. Don't all 4Runners have skid plates that protect the gas tanks?

    Could be a bad catalytic converter, but I think now we know why the truck was traded in early.....

    I am having an intermittent problem with the rear window and wipers front and back. Occasionally for no reason (although it may be related to the rear gate key switch) My center console window switch will stop working. When this happens, both my front and rear windshield wipers stop working also. After a day or two everything goes back to normal. Any ideas??
  • canddmeyercanddmeyer Posts: 410
    You mention all the windows being open. With the rear liftgate window being open, the aerodynamics of the vehicle are such that they'll suck some exhaust into the cabin. The liftgate window must remain up.

    Have you looked under the vehicle to see if anything is on the exhaust system that doesn't belong there, like maybe some undercoating overspray?

    Drive the vehicle for a few days with the windows up and the air running to see if the smell goes away. Let us know what you find. Good luck.
  • Ever since I got my 4runner, I thought the front wipers were noisy at times, especially if there was not enough rain falling hard. I have had them replaced once since them by the toyota dealer, but they still have a hard rubbing sound at times. Does anyone else notice this, and did you find a way to fix it?
  • chuck1chuck1 Posts: 1,405
    If at some point they were replaced by non-factory wiper arm blades (not just the rubber-the whole arm), this could very well account for the noise. This happened to me, the guy who works on my car bought cheap arms and switched them out for the original OEM arms. There is no guarantee that the dealer switched out only the rubber part. It's quicker to switch out the whole arm.
  • Chuck1, I bought my vehicle new and it has been on the noisy side since day 1. I cannot imagine the dealer switching them out for non-Toyota parts, and they were changed out completely, arms and all, but who really knows anymore.
  • chuck1chuck1 Posts: 1,405
    My Toyota dealer ran a "coupon special" for air filters. At the bottom of the ad it said, "meets Toyota Specifications but not Original Toyota Filters".

    In short - with dealers anything is possible.

    If your car is under warranty - take it to the service department.

    Hi kpust,

    Your problem is definitely the exhaust/converter. This is very common on 03-07 4runners. Toyota has a tsb and fixes this problem under warranty. For more info go to and google this topic. Lots of runner owners have responded to this problem and you can find links to the actual tsb in this very good runner site. I have an 0r SR5 runner with similar problem and have the tsb but have not as yet approached a dealer with the problem

    I have an '03 4-Runner with 104k miles. About a month or so ago, my brakes started to squeal. I figured this was normal since I only had replaced my brakes 1 time in the 104k miles.
    when they took the front wheel off (I do not know what side), they told me my calipers had seized up and they could not free them. This meant that they would need to start from scratch in rebuilding the brakes, and all associated parts/pieces/etc. The final tally came to $1062. However, now the truck stops worse than before. As soon as I started driving away, I noticed that I had to press the pedal to the firewall before the truck would stop. I drove back to the garage and told them of this.
    A mechanic test drove the vehicle, and told me that the new brakes needed time to get seated. He told me to give it a couple of days, and I should be fine. I asked him if there were any type of adjustments that could be done, and he said no adjustments could be made.
    It is 2 weeks later, and I am taking the truck back to the dealer. The brakes have not improved over this period of time.
    Has anyone ever had this problem in the past? Does anyone have an idea of what this issue could be? Is the mechanic telling me the truth about adjusting the brakes? It seems to me that the brakes have been adjusted in the past, especially when they start to wear out.

    Thank you for your help, and for reading this message.

    Sounds like he didn't properly bleed the brake lines.
  • Our dealer has recommended that we replace the water pump along with the other service work as shown by Toyota for the 90,000 mile service on our 2004 4Runner. We do only highway and in-town driving - no towing or other heavy duty work with the vehicle. We've had no problems with the water pump... and the suggested maintenance does not include replacement. Do y'all think we should? We'll be taking a 1800 +/- mile trip in August. Thanks for the input.
  • chuck1chuck1 Posts: 1,405
    You don't mention if you have a timing chain or timing belt in your motor. If timing belt Toyota suggests replacement at 100K. Also, the water pump is usually replaced at that time as well.

    If you have a timing chain, then it's up to you if you if you want to replace the water pump. AT 90,000 miles I would begin to think about replacement. At 100K I would replace it. Water pumps may or may not give a warning before they start to leak.Also, this isn't a job the dealer has to tackle. A good independent can perform this work as well.

    How much is your piece of mind worth in the heat of August driving almost 2000 miles?

    Only you can answer that.
  • Thanks, Chuck. That's good info, and we'll talk some more. ~~Arkansas Rose

    Thank you for your message....I told the mechanic to bleed the line......I am assuming they did, because now my brakes work like they are factory new.

    Thanks again!!!!
  • Just happened yesterday: turned engine on and 10-15 sec. later hear a click and RPM jumps from 750 to 1000 and it keeps repeating. Then later that day I shifted to neutral while on downhill and and again click and RPM jump to 1000 and back to normal. 96 4R 3.4L 6-cyl. with 90k miles. What that could possibly be?
  • help09help09 Posts: 2
    I have a 94' 4Runner, and it recently started making extreme noises, like a clicking and rattling. It happened when i was driving and saw that my rpms were very high, the noises are very loud and increase as i accelerate. My oil was checked for metal pieces and none were found. I'm told that it could possibly be a thrown rod, or rod knocking. Any suggestions? Any help would be much appreciated!
  • duke15duke15 Posts: 161
    Sorry I can't help directly, but I did throw a rod on a 93 dodge once and it had a definite noise like someone hitting the engine block with a hammer.
  • help09help09 Posts: 2
    Thanks anyways! So how did you fix it? replace the engine?
