1 Differential Unit problem

Failure Date: 12/15/2019

The rear axel and differential housing/casting is corroded thru such that oil is leaking through the differential hub onto the roadway and resulting in a loss of gear oil within the differential and axels. After driving on the highway this oil was observed on the spare tire (mounted under the bed) and up the back of the bumper. The service representative at one dealership I approached to discuss the cost of repair indicated that they have seen the problem multiple times. This obviously should not be happening and I believe it to be the result of a defectively designed/manufactured component. I have not yet had the vehicle repaired due to the high cost, but it is not driveable as the differential will not hold gear oil.

I find it interesting that my 2002 Toyota may be recalled due to the spare tire mounting being rusted. I have been very disappointed with this truck since the gas tank the rear differential cover and fuel lines have rusted through. I bought this vehicle due to the Toyota reliability reputation. Would you please review the frequency of rust on these areas and issue what ever recalls appropriate.
