3rd Generation Toyota 4Runners 1996 to 2002



  • My '98 4runner is in desperate need of new differential fluid but the last idiot who had the the truck stripped the drain plug and now it is truly a pest to try and get the drain plug out. Im afraid of stripping it more or possibly cracking the transfer case. Yike$$! so any advice on my situation??
  • I had a similar problem when i had my fluids changed out at some Jon-Smith shop vs. a dealership. The dealership was able to order a new screw as well as air-impact out the old one which solved the problem.
  • Hi there! I have just bought a 99 4runner, 2.7 liters, manual gear, at 50k miles. Great car! I have just made my first trip and took 110 miles of very cold weather. The engine runned "cold" all that mileage. Also "drunk" a lot of gas ... does s'o knows why? That happened?
    In time...there is another car been sold. It is 2.001 model, has a 3.4 liters engine and automatic transmition. Same mileage. In your opinion s it worthy to spend U$ 12k and trade in my 99?
    Thanks a lot. In time... I`m writing from Brazil, Sao Paulo.

    Your '99 4Runner is a very low mileage car! Unless you're having serious mechanical problems with it, I don't see why you would want to trade it in for the additional expense.

  • I hit the button to engage the 4-wheel drive on my 99 4Runner Limited, but the dash indicator wouldn’t lock-in green. When I realized I had a problem I hit the button to turn it off, but dash indicator continued to flash and now it won’t stop with button in the ON or OFF position. The truck drives / feels like 4-wheel drive is engaged, but now I can’t turn it off. Fluid levels in the differential and transfer case are full. I’m afraid to drive it, don’t want to cause any damage. I’m equally afraid to take it to the shop without same idea of what the problem might be…….. Help…..Please.

    I suspect one of the front differential sensors is bad. That seems to be a fairly common problem with the '99 4Runner. Anyone here have direct experience with this?

    If anyone could give some advice with this situation, I would greatly appreciate it! I have a 1999 4Runner Limited 4 wheel drive with 147,xxx miles on it. My problem occurs either while accelerating to or while in park and revving engine to about the 4200 RPM mark. The best way that I can explain it is it just feels like the engine stutters or how it would feel if hitting rev limiter or some sort of misfire. I have had a lot of work done to it this year, but what I have tried in regards to this problem is swapping out the ignition coils (bought one and basically swapped out each one, one at a time to see if one was bad), replaced the mass air flow sensor, replaced pcv valve, replaced plug wires, and it does have newer (new in spring of 2007) spark plugs. There are only a couple other things that I can think of: one is a bad ECU, but I have heard these usually don't go bad and I don't know where it is exactly in this vehicle to be able to replace it. Another thought is bad oxygen sensor(s), but am not sure if it could cause my problem.

    Any advice, again, would be greatly appreciated.
  • Thanks for your opinion! I also heard that the V6, here in brazil, has a very expansive maintenance (IF, and WHEN needed) so I´ll keep my 99 for another 50k miles.
    Please about the engine "running cold" do you have any clue about that? Nice to talk to you!

    Welcome back!

    It's possible that your engine is running cold because the thermostat is defective or its temperature rating is too high. I would check that out first.

  • I have a 1997 Toyota 4Runner SR5 with premium sound 3 in 1 combo system w/6 speakers (radio part# 56807).

    Can I pull this out and install into a 2002 4Runner with the lesser powered 3 in 1 system (part# AD6803)?

    Is the amp built in to this radio or is it separate and are the speakers the same type on both vehicles?
  • First, Thank you for the info. I greatly appreciate it. I called a local Toyota service center to order a replacement A.D.D. sensor. They said they showed a #1, #2, or a #3 for the 99 4runner. Parts man thought I need a #3. Took it to the shop to have it installed wouldn’t fit......wrong one. Shop said the dealer should have used trucks V.I.N. # to identify correct part. How many sensors on the 99. Any insight would be appreciated.
  • my 96 runner has 224,000, i'm getting about 12 mpg. where should i start? air filter? plugs? tune-up?

    Hello, I had the same Electrical wiring harness problem on my 98 4Runner SR5. It made me crazy trying to figure what was wrong. It turned out the harness was defective and Toyota replaced the Tow hitch harness with a new one at no charge. The car was 4 years old and out of warranty, but they they replaced it free. You might want to check the chance of a TSB in relation to your wiring harness for your model year. Hope this was of some help. Ben.

    Can anyone please tell me the purpose of the ETC button on the right side of my console. Also when would I use it with the O/D in the off position. As it stands now I drive the car with the O/D on for better fuel economy. The car has 61,000 miles, and I had the Trans. fluid flushed and filled by Toyota at 47,000 miles. Am I doing damage to my Transmission driving in the city with O/D at all times? Any input would be of help, and better understanding for me. The car is perfect in all respects. And I'd like to keep it another 10 years. I also use synthetic engine oil. Ben.

    224,000 miles is terrific.. Have you considerd having your injectors cleaned, or even checked for bad ones? With that kind of mileage I would also the consider the Fuel Filter and pump. Even having the Fuel lines blown out and clean. With 224,000 miles you make me proud and secure in owning a 4Runner V-6. I don't know how often you tune your car, but I would also consider a complete tune-up, wires, plugs. filter. If finances allow I think my first choice would be a Toyota Diagnotsic. It's through, and for sure you you'll know your problem{s} Sometimes going thru the car yourself replacing everything, and there are many things to consider, you may still not find your problem. And it could cost you alot of money, and needless to say much frustration.
    Good luck. Ben

  • All I need to know is what bellhousing will fit on my 96 2.7 4cyl with the 5 speed. Is it the same as on the V6? The Toyota dealership cant seem to tell me... So maybe someone with some real world knowledge on here might know?
    Id be willing to swap the whole trans if it'll fit. Im just having trouble finding a trans from a 4cly and I dont wana buy one from a V6 and have it not work...
    Any help?
