Rear Diff Gone Bad At 48K Miles???

Georgia-4Runner · 2009-12-07T15:39:46+00:00

Hey everybody, I have been hearing a whine-type noise from my T4R ever since I bought it about 10K miles ago. I thought it was noise from the old tires I had on it, but I put on new tires about 4K ago and the noise is still there....and getting worse. I took it into the dealership this weekend and the entire rear differential and right bearing are coming to pieces. The rear diff fluid was FULL of metal flakes. I was very surprised to hear this news with only 48K miles on the car. Has anybody heard of this happening? It has done some towing of a 4,500 lbs. horse trailer, but nothing extensive. Oh, I have the V8, 2WD, LSD, Sport. The whole repair is covered under warranty, but was still curious. Thanks for your help! Steve

All 3 differentials?

I thought there were two. Is the front differential hard to access?

Simple drain and pour?

How may quarts did you use up?
