Driving in mild winter condition (light wet slush) on a maintained highway my 4runner began to fish tale. When an attempt was made to correct the fish tale no control input from the drive would correct the sliding motion. This caused the vehicle to slide toward the shoulder of the road. On the shoulder of the road the vehicle began to slow to almost a stop, however, the rear end was far enough off the shoulder that…

Vehicle began to sway violently while driving on the interstate. The weld joint which joins the rear drivers side lower control arm attachment point to the frame had separated allowing to control arm to move forward an back. This in turn allowed the rear axle to turn from side to side. On inspection the frame is heavily rusted in this area and the weld has given way and is tearing apart from front to back. The joint…

Experienced soft hum like noise. Took vehicle to local toyota dealer for diagnosis. Rear end housing found to be severely rusted to the point where the internal fluid is seeping out thru the rear of that housing. Non reparable, needs replaced minimum $3000. Dealer said this is not an isolated problem & had contacted toyota of this situation. Dealer was told it happens & toyota would not do anything about it. Has…

Rear differential housing is rusted very badly leaking gear oil. Rust is extremely thick. Huge flakes more like chunks. Leaking from rear of housing where rust has penetrated far enough to cause a slow leak. Rest of 4runner is in good shape. *tr

The rear axle housing has rusted through such that differential fluid was leaking through a hole in the metal and dripping onto the roadway. The metal was so thin, like paper. This is a safety issue since all of the rear axle fluid could leak out, allowing the rear differential to freeze or seize up, causing a loss of control of the vehicle and creating a possible accident. It could also cause other vehicles to lose…

When getting the left/rear wheel bearing repaired (due to heavy rusting of the differential housing, causing fluid loss), the technician reported extensive frame loss also due to corrosion. Affected vehicle (otherwise in good condition) was/had to be junked for safety reasons, thus forcing me to purchase a new vehicle sooner than anticipated. In n.e. (north east) usa, toyota tacomas (frames manufactured in the usa)…

My 2000 4runner is rusting out next to the rear passenger wheel well. It's always been parked in the garage. I take it for regular washes--and this still happened. I purchased my 2000 4runner brand new with an additional undercoating protection--but you would not know it by looking at the rust damage. This is the telltale spot, it seems, for 4runners rusting out. This is unacceptable toyota!!

No injury or crash . . . Reporting what i believe may be a design defect which could potentially be a safety danger. --- the rear differential housing in the 2000 toyota 4runner i own seems to be rusting unusually quickly. This is a 10-year old vehicle, but it only has 113,715 miles on the odometer when it sustained a leak due to corrosion. Apparently this is a known issue as both the local toyota dealer and my…

2000 toyota 4runner 6cyl 78000 miles. Noticed rear end differential is leaking oil. Dealer says it is because i park it on dirt driveway. Not leaking at seal or normal connection point. Is coming through the metal itself. They said the metal has become ' porous '. Last 4 runner had 340,000 miles on it and never had a drop come through the metal and was used extensively off road. This vehicle minimally. This is…

Rear differential cover is rusted and fluid leaches right through the metal spraying fluid on to spare wheel and rear bumper and anything in tow. Cover is evidentially cheap metal and is poorly designed as the cover is welded on and cannot be replaced without replacing the entire rear axle. There is no other significant rust on this vehicle and the remainder of the axle is in very good condition therefore i believe…

Rear differential housing completely rusted through such that differential fluid is leaching directly through the metal and dripping onto the roadway. This could result in the differential seizing up and causing loss of control of the vehicle, or other vehicles to lose traction on road due to gear oil leaking onto roadway. Toyota does not sell differential housing and insists entire differential must be replaced at…
