Diff grease

[Mikey D]

Hey guys, just wondering what some of yall are using to get more of a posi trac style diff. Ive always used auto grade grease due to me having an unlimited supply. I'm gonna use somethin thicker since ive got them apart.

i ran 100k diff fluid and its tough to get out but it acts like a locker for the diff
