Rear wheel bearing spacer
Posted: Wed Dec 28, 2022 4:48 pm
Hello,
I've got an 1982 320i. I'm gathering parts to rebuild/restore the rear end.
I picked up a pair of 323 trailing arms, for a rear disc conversion. After taking those apart and understanding the diagrams vs. reality - a question.
I see why they use a wheel bearing tube spacer. However, if you measure the tube length, you'll find that it is a few mm longer than the machined lip/shoulder within the bearing housing. This is where the variable width shim comes into play. These shims are NLA. But the more I look at it though, I'd just assume one could turn down one end of the spacer tube to match the exact width of the shoulder spacing.
Not everyone has a lathe at thier disposal, so yes, the shims make perfect sense. But if you can't get said shims for such a spacing measurement...then why not narrow the tube to fit. It's one in the same, yes?
