Two problems related to front suspension control arm have been reported for the 2002 Toyota 4Runner. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Toyota 4Runner based on all problems reported for the 2002 4Runner.
Frame rust on the inside portion for the frame. 33" hole rusted through completely on passenger side. Rust continues about 80% of the way through the rear lower control arm mount. Driver's side has a similar amount of severe rust that has weakened the structural integrity of the frame to the point where it is no longer safe to drive. Should the CO troll arm mount finish rusting through, the axle will no longer be attached to the frame on that side. There is noticble flex and sound associated with the frame rot. It is only a matter of time before the control arm mount disconnects completely, or the frame buckles.
This is yet another costumer of the 4runner 3rd generation complaining about the frame rusting out. There needs to be responsability for the bad frames on this year 4runner. My frame has holes in the rear control arm attachment area and more rust all throughout entire frame. I'm doing all I can to keep my frame from getting any more rust on it and keeping it safe to be on the road. I strongly believe Toyota should also have a frame recall for the 4runner like it did for the tundra tacoma and sequoia frames.
