I have now experienced the failure of the second rear wheel bearing on my 2004 Volvo xc-90 AWD, with the second failure resulting in the partial separation of the wheel from the vehicle at highway speeds. There is a defect in the design of the wheel bearing, and these bearings should be replaced in the field before ther is a fatality or serious injury. Although Volvo has replaced both bearings under warranty, a brief internet search indicates this is a very common failure on this model. Damage on the second failure resulted in $1800 damage to the vehicle.

I have my 2004 XC90 T6. At about 34K miles a noticeable 'thrum' began somewhere in the drivetrain. Original diagnosis was worn tires. After replacing tires, the noise has become worse. Now at 35K miles is very loud. New diagnosis is failing wheel bearing. A bit of research indicates I am not the only XC90 owner with a wheel bearing failure. Wheel bearing failures at 35K miles this should be declares a defect and recalled. Please research this problem.

Wheel bearing failure. Volvo XC90 put an SUV ontop of a car chassis causing too much load on wheels and wheel bearing. Tires wear out often and bearings need to be replaced repeatedly. If you search forums like:townhalltalk.edmunds.com/direct/view/.F0ed3F5/0 forums.swedespeed.com/zerothread?id=77305 www.Volvo-forums.com/T7392-reliability-concerns-about-2006-XC90.htm you will see that many car owners have this same problems. Volvo need to let customers know that this is a problem. This is dangerous and can cause serious injury. Instead of keeping it hush they should inform consumers and do a recall.

Wheel bearings have been replaced twice under warranty. The problem has recurred. This part needs to be recalled.
