Shaft adjustment on rear axle of m38a1

[serge]

Hello
During the dismountage of the shaft of the rear axle of my JEEP M38A1C (in the aim of replacement of the inner oil seal), I saw some shims between the bearing and the bearing retainer.These late where only on the left side of the axle.
On the technical manual I own : TM 8014 OPERATION AND ORGANISATION MAINTENANCE , there is no explaination about these parts. I suppose that they should be used for a specific adjustment
Is any body who could to explain me the method that I have to follow for the adjustment using these shims.
Regards

I am referring to a US publication (a reproduction - "Service Manual" for the M38A1 from Original Reproductions in Upland, Calf.) which shows the shims between the the axle housing and the bearing retainer, which is behind the brake backing plate. The manual says to add or remove shims to provide .003 to .007 inch end play in the axle shaft. With the wheel hub and brake drum removed, it says to test the end play by moving the shaft in and out. The end play should be just perceptible.

I've never done this, so I don't know how difficult it is, but that's what the manual says to do.

Hello

I thank you very much for your information about the shims. So these parts are used to adjust the constraint of the shaft on the differential. If you have to change the inner oil seal , the big problem is the extraction of the hub which need a very big tool as showed on the pic following .
Best regards
