Started hearing that familiar rumble on my '78 240D the other day and knew the time had come for wheel bearings. Got 'em at my local Car Quest Friday with the intention of doing them Saturday (which is why I didn't get them from Q). Saturday came and I had no energy, instead I used my new scale to pre-weigh the grease into little plastic containers from the Chinese takeout. Worked sweet BTW.
Today I finally dug in, guessed the driver's side was the immediate culprit, and it appears I was right. Much more play in the outer bearing than in its replacement, a little more wear and the rollers would fall clean out. Guess I waited a little too long for this job. I *think* I did the other side a year or two ago. Anyway the strange part of the whole thing was that the seals I'd gotten are WAY too small, probably 1/4" smaller than the inner bearing itself. Fortunately I'd gotten lucky and didn't damage the existing seal and got it back together with that. W123 bearings are easier to setup with my dial caliper than W201 owing to a larger hub. 60g of grease is much more than I thought it would be, I'd actually weighed out 60.5g as I figured I'd have some wastage which I did in figuring out which way the seal went on. Took it for a ride and the noise is GONE. The guy at Car Quest tried 3 different methods for looking up the seal and came up with only that one part number. I tossed it over to Q, I've got a spare set of bearings now, I should have a spare seal to go with them. -Curt _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
