Yup, does not sound there are happy times ahed for you. Sorry

 

As allready ststed, you will need to properly set the new carrier up. You cant just intsall a new carrier and use the old carrier shims. the old shims for pinion depth usually get you close, but not the side shims, although they are a good START.
You need to use marking compound.

Is this an Eaton LSD, if it has clutches its not a locker, its an LSd.
