Cj AMC 20 Moser Install Problem

Just tried to install my new Moser 1 piece axle on passenger side. The backing plate bolts are getting tight before the backing plate mates up with the axle flange. Also the axle is impossible to turn by hand.
Old axle lengths were dead-on the diagrams included with the new axles.

Bearing stick-out from the housing was 0.081" so I used one of the 0.030" shims that was originally installed on the driver's side. Shim is between backing plate and axle flange and it's ID is larger than the bearing.

I loosened the retainer plate bolts and the axle freely turns.

I called Moser this afternoon but got the we are closed message. Will call again Monday.

I've seen where some people have removed the thrust block in the diff on this install. Is this a common issue/fix?

My new axles were flat and square on the ends, an issue I read on previous posts.

I am a little concerned about the direction of the bearings on the axle. Moser's diagrams / instructions could use improvement. I have the bearing pressed on so that the cone of the bearing is pointed AWAY from the differential. The larger shoulder of the inner race is against the press-on ring and the shorter shoulder is against the step of the axle. Is this correct?

I think your thrust block is the problem. I have a similar problem trying to reinstall axles that were installed in the late 90s with a crosswalk stor I think your thrust block is the problem. I have a similar problem trying to reinstall axles that were installed in the late 90s with the thrust block still in place.
