HI. I have a 94 YJ Sahara with a Dana 35 w/o ABS tagged 52068849. This means it does not have a locking differential. Does this also mean that it is not a limited slip rear axle? I am currently replacing the axle fluid and I was wondering if I need to add the extra gear oil additive friction modifier. I will be closing it up with a paper gasket and RTV gasket sealer (permatex blue). Someone else used some orange gasket maker and made a mess with over use and the bolts.
tnx...
