After noticing a strong gear oil odor and seeing the actual gear oil on the back the of the vehicle I was alarmed to find out that the rear axle housing had rust perforating the rear of the housing. Once the housing was checked by a certified mechanic and turned away due to fear of destroying the housing, I removed the vehicle from the road.

Rear differential rust through.

2002 4runner SR5 4WD, 141K miles, completely rusted through rear differential, both rear axle seals busted out, differential housing has several pin hole leaks and is thinned out, the only fix is a completely new rear end, which is very costly, I am the 2nd owner, I've owned a 99 4runner that had these same rear differential rust issues, the rust is ridiculous and has deteriorated the whole undercarriage and my 4runner is garage kept and I wash it all the time. I can't believe Toyota has not been held accountable for the rusting out of rear differentials and rear axle issues.

I am the original owner of a 2002 Toyota 4runner-SR5, sport edition with 74,600K miles. In November 2009, I experienced the same problem that's being reported by other Toyota owners whose vehicles are being recalled. The accelerator pedal stuck in a partially depressed position on its own and quite suddenly. This occurrence only happened once. The engine was racing at a very high RPM and my rear tires were squealing loud enough to draw attention from passersby. Luckily for me I was slowly pulling into a parking slot. My reaction to this situation was to put the gear in neutral and applied the brakes. My main concern is if the ongoing investigation by the NHTSA and Toyota will include a look-back at earlier models for these known problems" and, if so, what is the manufacturer's recommendation to owners' with earlier models"
