Re: Rear Wheel bearing Endplay

You should make sure that the bearing cup (the outer ring) is pushed all the way into the axle housing.
That may not give a correct adjustment. Yes, both backing plates need to be installed to check the end play, but not the drums. But you don't press the cup in as far as it will go, you want it to be flush with the backing plate. If not, the forces of driving the car will eventually move it to that position which will increase the end play.
For cars with a single tapered roller bearing on each side, the best way is to leave the cup protruding a few thousandths beyond the axle flange and allow the tightening of the backing plate and shims if present to push it in so it's flush. Same on both sides, then give the far side axle a wrap with a hammer which will displace both axles via the thrust block to the near side; then go to the near side and check the end play. If you then give that axle shaft end a wrap to displace the axles in the opposite direction, you should get the same end play clearance reading on the other side.
Just to complete the picture for the earlier AngleSet rear axles using dual opposed tapered roller bearings on each side, each axle is fully independent with no center thrust block. Hence they are adjusted individually at each side via shims behind the inner cup (which can be a royal PITA), as shown in the following picture. If you have this style axle you might want to see:http://www.packardclub.org/forum/viewtopic.php?f=15&t=266&start=10
