I have a constant 'roar' coming from the rear end - both rear wheel bearings were changes within the last year, and the sound doesn't go away when I put my other set of wheels on.

The pads and rotors have about 27k on them. There is no significant wear on the pads, but the rotors have developed a slight lip. (Autozone pads and rotors).

Is it time for a full pad and rotor change in the rear again?

Rear diff? I'm not sure how it could be brakes.

The rear ones go all the time on these cars for some reason...

Does the sound get quieter when you turn the car left or right a bit at speed?

No changes in sound when I swerve / change the load on the rears. Nice Santorin's in teh sig

hmm, maybe like 4driver4 said - check rear diff fluid? btw, the right one isnt santorin :P

filler cap off. I got my hex socket in there, but it wouldn't budge, and I believe it rounded out slightly. Guess I'll have to deal with it soon, eh. I've read other threads on how to get it removed, so, guess I'll do some digging.

yep...I had to pay a shop $100 to remove mine

the sound based on load. So I wouldn't rule out the bearings.

I heard about the crappy Optimol bearings. I don't think I have those. Unless that's what ECS sells
