Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

1998 Toyota 4Runner Owner Comments

problem #3

4Runner 6-cyl

Rear differential housing is leaking fluid as a result of rust. Local Toyota dealership says the entire rear axle needs to be replaced (it is all one piece) to the tune of $3000. An online search of a diy repair shows this problem (google: Rear differential rust) shows this problem is unique to Toyota 3rd generation 4runners. This amount of rust on an integral part is extreme and unacceptable that Toyota has not done a recall, even though they did one for virtually same vehicle in the Tacoma for frame rust.

1998 Toyota 4runner SR5. The read differential housing has rusted out so bad that it has to be replaced. Multiple mechanics have stated they've never seen such a thing. No accidents or anything that could have added to the deterioration of this. This 4runner has never gone off road and 90% of is highway miles.
