I have a '91 M5 (6/90) build date and am trying to replace the stock steering wheel with an M tec wheel from an E30. Got the original wheel off with no problem. Installed the new one and everything seemed fine, until I took the test drive and noticed that when I turned the wheel seemed "catch", almost like the wheel lock was trying to engage. Got it back and tried to remove and it won't come off the spindle. The wheel has some up & down play but not much....anyone have any ideas on what may be keeping the wheel from being removed???? Thanks,
