Well, I solved my diff seal problems. I thought that would also fix another problem I seem to have. Apparently not.

About a week ago I started hearing something like monster truck tires. I can start to hear it around 25-30 mph and around 50 it's extremely loud and there's a slight vibration. I'm pretty sure it's coming from the passenger side rear, but I'm not 100% sure. I put my car on jacks, took off the wheels, and took a look, but I couldn't see anything (maybe because the sun goes down at 4pm here [:@]).

Anyone have any ideas? I'd like to have a shop take a look, but I have no time or alternate car.

edit- Maybe a wheel bearing?

 

It's a bad wheel bearing. [:@]
