It _should_ be a passenger'* side wheel bearing. Usually when the weight gets tranfered to them they "hum" louder.

But jack it up and grab it at 12 and 6 and try to rock it back and forth.

Hey guys. It is the wheel bearing. The left is gone, and the right one may be going also.

The question is: does it have to be Delco, or will an aftermarket do? Delco is about $100 more (about $300 Cdn) than the aftermarket, but I am told that aftermarkets are not as quiet.

What is everyone'* experience? What did you guys use?

Not as quiet? I'm calling BS. It'* a machined bearing race with bearings and grease. I've never heard a bearing UNLESS it was bad. I don't see what difference it makes WHO makes it as long as it'* made with quality materials and proper machining.

Either way, even with Delco and both bearings, you're talking an extra $200. Your Transport is 8 or 9 years old. Extra cost for Delco boils down to about $25 a year. This isn't exactly the end of the world, but if you keep driving on bad bearings, then it could actually be the end of your world.

My advice:
Pick one, but get it fixed.

Hey guys. I changed both wheel bearings and rotors and pads. The noise from before is gone, but there is a new problem. When I turn right or left, there is a clunk sound. It happens while driving as well as parked (not on bends, but 90 degree turns). I think it is coming from passenger side.

I haven't looked into yet, but did some search on the forum. It could be possibly strut bearing (which needs lubing). Any other things I should look for? I'm sure everything went OK during the wheel bearing replacement. The rear bolts were difficult to get to, so we had to turn the wheel side to side several times with the car off to get leverage. It was a bit harder to do at the end. I hope I didn't screw up something.
