8-3/4 clutch type Dana power lock

am i the only one that checks the preload of limited slip differential carriers after a rebuild or when bought new to make sure they operate properly. some one on here must have some info.

guess i'll have to give Cass (Dr. Diff ) a call and pick his brain.
I've rebuilt several OEM units using the kit Cass sells and never had a problem. The aftermarket unit may not be the same disk count. Cass has always been helpful when I ask questions.
