pulsing noise from the back
 

Just recently I discovered that my 1985 190E is making a deep pulsing noise from the back when driving, it's not loud and can be heard at mid range speeds 50-70 kmph the most.

I just had new flex discs put in, the differential is in perfect condition, no slack at all, it just leaks a bit from one seal. My e-brake lines for the rear are toast, so I was thinking that maybe it's the brake not released all the way, but if this was so the wheel would heat up, but it does not.

I also noticed that one wheel spins much easier then the other, I guess I have to take it apart and see what's up, could be bearing going....

anyone heard of anything similar?
