She is on the way back from Lansing to Detroit area and there is a noise that varies with speed coming from the rear of the car. My thought is wheel bearing. She is concerned about a failure but the posts I found did not indicate anything other than the noise getting louder. Tried searching for replacement instructions but could not find one. I seem to remember a post where the member provided part numbers and I think some instructions. If anyone can point me in the right direction it would be a help. Thanks.
