When Checking rear wheel bearing play by
tilting the wheel I found a barely detectable rocking.

As soon as I found this (rear wheel play) I drained the rear drive fluid. It came out as clean as it went in. There are no leaks around the drive and everything else seems normal. The wheel spins freely, and there is no detectable rolling resistance.
I checked the BMW manual and it says to Shim? Or replace bearing (see below).
Anyone experienced similar issues?
Can this issue wait till next service in the fall, or is it a “must do now?”

Thanks in advance to al that reply.

Checking rear wheel bearing play by
tilting wheel
(Inspection III)
• Tilt the rear wheel to and fro across its axle.
• If play is detected, fit new shims to rear wheel
drive or replace bearings.

Did you notice any noise? Maybe a light harmonic sound as you went up through the gears?

You want to be sure that the play is not in the swing arm pivot bearing. This is a much easier fix and much less costly. Just had mine replaced. It will show up as movement of the swingarm and the final drive assembly together.

drifter36,

Thanks for the input

I've isolated to problem to the swingarm pivot, as the rocking is detectable when the rear brake is applied.
I also found that the play is only detectable at certain points on the wheel like positions 1 o clock and 7 o clock. I think that if it was the wheel bearings then it would be congruent throughout the circumference.

How big of a job was it to adjust/repair your swingarm pivot. I've been looking through the BMW service manuel and it seems fairly simple except for the special tools needed.
