Re: Advice needed - recurring rear axle oil seal leak
 

Just an update on this thread. Despite Bill's diagram, the D44 on the
86 CJ7 in fact has only 1 seal per side and it is outboard from the
bearing. There is no grease seal, so the bearing is lubricated by the
axle oil. This was confirmed when mine was taken apart again in the
process of confirming that the rear-end is not salvageable due to a
spun bearing (compliments of the PO) - appears as though the housing
has been stretched/warped by the heat and will no longer hold a seal.

Re: Advice needed - recurring rear axle oil seal leak
 

Thanks for the update!

Now I know what I am in for when I open mine up, a trip to a shop to get
the new seal and bearing pressed on.

Re: Advice needed - recurring rear axle oil seal leak
 

OK, Thanks for the report on your 1986 CJ-5. They must have change
it to the AMC 20 design, I previously thought only Chrysler/Daimler
would f**k up a Dana.

Re: Advice needed - recurring rear axle oil seal leak
 

That would be unlikely seeing as they ran out of the 20's for the last
of the CJ7's and used the Dana 44. I can't see them reinventing
something for the end of a production line.
