Today on my lunch break I started to feel a little vibration coming from the rear of the car. I inspected all four wheels and took a look under there but I don't see anything out of the ordinary. I'm going to head back to the workplace and get it jacked up to get a better look now.

I know all my shocks are completely blown on this car (original shocks at 130K miles lol) and I have new ones on the way. I just replaced the front control arm bushings, rear lower control arms & ball joints.

I noticed my driver-front fender liner is getting chewed up... I'm gonna take it out and see if that's the cause but I don't think it is. It's also worth noting my diff is leaking from the input shaft seal, but the fluids were recently topped off.

Any ideas?

Check the rear wheel bearings.

I had a vibration/drumming sound start and it got progressively worse over months. When I had the rear end up off the ground, you could feel the difference between the good bearing and the bad side when rotating the tire by hand.

Yup, if the vibration changes when you are driving on a road and swerve left vs right, then it's most likely a wheel bearing. Usually if it gets worse when swerving right, it's the driver side and vice versa if the noise gets worse when swerving left.

Thanks guys. Wheel bearing was one of my first suspicions. Can't wait to get the rear end up to figure this out.
