<E30> RE: Road noise

Casey,
While I agree with the diagnosis by Erick (bad wheel bearings) I disagree with 
the procedure.
You do NOT need a $500 tool to replace the bearings.
A simple puller (preferably 3 prong) is all the special tools 
required, available for about $30 or can be rented from a tool 
rental place for $7.
Let me know if you need detailed instructions.

Erik, 
Who told you that E30 M3's require wheel bearings at 40K intervals???
My 89 M3 has 91K miles with a few autocrosses and driver's schools 
and the bearings are tight and make no noise.
My 86 325es has 180K miles and I replaced the front bearings at 120K 
but the rear are original with no signs of dying. This car is 
autocrossed twice a month on R1's and has been to 9 drivers schools. 
I consider the BMW sealed bearings to be very hardy and since they 
are sealed, never have to be "repacked" every time you do the brakes.

noise--I replaced the rim but the rumbling has not diminished.  The 
tire is
not cupped and has been balanced.  What else could it be?  Wheel 
bearings?

Your wheel bearing is junk.  Whatever wrecked the wheel made the 
balls leave
their marks on the races, and you hear them going over this uneven 
terrain.
Go to a shop and get it fixed.  You probably don't have the $500 
bearing
puller tool.
