2008 Lexus GX470 Q&A

2008 Lexus GX470 Question: rearend noise

I have a 2008 GX470 and hear a high pitch(whine)that seems to be coming from the rearend when on the highway from about 50 MPH up. You hear this when the car is pulling and quits when coasting. Wondering if anyone else has had this problem. -
Answer 1
I have seen tires cause this but a more common issue is war in the rear axle housing. Greg -
