John,
Sometimes the metal around the center bearing gets bent and rubs on the
rubber causing a wub wub wub sound, only audible at low speeds, or at
least that was the case on my friends '88 325is.
Solution?
Buy and install a new center bearing, or for the financially challenged,
spray W-D 40 on it every time you're under the car. His is still running
3 years later.... wub wub wub....

Subject: <E30> Wub wub
Hello,
I've got this road speed-dependent "wub-wub-wub" sound coming from I
believe the rear of my 1986 325es 150k. The rear bearings were replaced
about 30k ago, but other than that not much has been worked on back
there.
The diff leaks at the flanges, but slowly. Any ideas what to look at?
Bearings? CV joints? E-brake? Wheel out of round? I'm not sure what
common
problem areas there are. Oh yeah, and it's semi-intermittent, meaning
sometimes it's not there (or at least I can't hear it), but it IS there
about 85-90% of the time. I'd appreciate any ideas, and many many thanks
in advance.
