on a 02 trailblazer, I replaced the front wheel bearing on the driver side last fall, and the wheel bearing on the passenger side last night. My grandpa is still complaining of a rumble/noise from the passenger side front. Is there some other bearing that I missed that could cause this?? thanks.

rumble

I have the same issue on the same year car and its driving me crazy. I suspected the tire because the rumbling even happens if the motor is in neautral and rolling downhill, but they are new and don't show any kind of defect. Also it goes away when making left turns leading me to believe it's something on the passenger side. The upper rubber ball joint (?) on the passenger side is split. Is there anything I can do to troubleshoot before spending money on having it replaced. Thanks for any input.

Usually, if the noise goes away when turning left, the left bearing is going bad.Turning left unloads the left bearing.:m2:

the tires are good, and were rotated to verify this wasn't the problem. there is no other joint other than the cv joint on the front right? not like some mystery universal or something??

There is a bearing that comes greased from the factory, and sometimes fails, at the passenger side of the oil pan, where the CV shaft splines are inserted. You have to remove the CV remove this assembly for inspection. It's where the electric front axle actuator sits. Search for "splined shaft disconnect" for previous discussions and picsc of this unit.
