Rear Brake Backing Plates Loose?
« on: Sep 26, 2006, 09:55:04 AM »
I just took my axles out to change a third member and I noticed the backing plates wobble a little bit.  I have the wheel studs on a flat surface and the plates feel loose around the axle shaft.  Is this normal or should I replace bearings?  If the later, how do I replace?

They wobble right on that dark line the arrow points to.

OK, the more I think about this the stupider the question seems.  I think it's pretty obvious my wheel bearings are shot.  Looks like I'm in for some good old fashioned "Concrete Hatin'!"

Wait, dont change that bearing quite yet.

The backing plate MUST wobble because the wheel bearing is a high performance bouble sealed roller type. To remove the wobble, it would require a double row tapered timken style bearing set similar to what is used in the front hubs!

After you install a new bearing [if you need it] the backing plate will still wobble.

It is always better to replace an old wheel bearing, however, first begin by carefully prying off the tan colored oil shield, and inspect for pits and/or debris in the bearing.

If you did not have any axle bearing noise before you removed the axles, chances are your old bearings are still serviceable. Always insist on using the original quality bearing [Koyo] and a good quality seal. We sell a very high quality bearing kit that includes everthing you need.

Thanks a lot, Marlin.  Maybe I'll wait to change the axle bearings but I think I'll still change the seal in the axle housing while it's all apart.
