Possible hub bearing issue?
'96 Lumina with 144K, just recently noticed a mild vibration at all speeds, but more pronounced at hwy speeds coming from the front end. Seems to be the left, but haven't ruled out the right yet. It's more pronounced when braking, especially from 60-0. It's definitely not just brake rotor related because it happens when I'm not braking, and it is more pronounced when curving to the right and not at all noticeable when curving to the left. I'm leaning towards thinking it's a bearing hub assembly, but the fact that it's significantly more pronounced when braking is something I've not heard of in relation to a bearing hub. I'm going to jack it up tonight and listen to the bearing hub with a stethascope on both sides and see if I can identify anything.
Any other ideas? Does the braking thing fit with the bearing hub issue?
