The thrust block that is pinned between the axles in the centre of the spiders by the cross shaft, is it retained or disscarded with a locker install?
The instructions with my Lokka dont mention the block,
Is the thrust block cridical to the otter bearing preload?
 
You keep it unless you are installing 1 piece axles. And if you are not, you will be soon. Almost as sure as death and taxes.

Exactly right.

Most 'locker' installations are a carrier change. So, NO-You don't keep it.
BUT-With the maker your using. I would call them.
X2 on get'n 1 piece axles-Go with Moser. They are the BEST!
UPDATE-Just look'd at the LOKKA site, couldn't find a PN for the AMC mod 20 rear?????
