[Chrysler300] Shimming rear wheel bearings, 300H

["Michael Moore mmoore8425@xxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

I am in the process of  shimming rear wheel  bearing clearance on my 300H. 

I am following the shop manual but ran into a problem for which I need advice:

Following the shop manual procedure, I installed the axles with new bearings (installed by top machine shop).

With axle and bearing installed, on one end of the axle housing, I installed .040 of shims.
I then installed the outer cup using a large brass bar and a hammer.
I pressed it in using the brake backing plate and cylinder support and the 5 nuts.
I ended up, per instructions, with the outer  race flush with the shims and not the housing.


On the other end, I carefully installed the outer cup the same way, except without shims, and pulled it in just until
the clearance was gone from the bearing. So far, so good.

The next step should be to remove the backing plate and measure the protrusion of the outer cone and add .018 shims to that measure protrusion to determine total shimming. Then subtract that total number number from shim pack (.040) on other side, and if the difference  was .020 or greater, balance out the total shims so they are roughly equal.

My problem is that  when I removed the backing plate, I had no protrusion. The outer cone sits flush when looseness is gone, That would say I should add .018 shims, to this side, and perhaps move my .010 shim over so I’ll have about .030 on each side.

But right now, what will happen is there will be no axial clearance until the axle shaft expands and pushes the current side out that .018 or so as I see it. Does that sound right?
Thanks,
Mike Moore
