What TG said.
Just did my carrier bushing & u-joints, while doing a total Brakes replacement. Much easier if you have, or have access to a Press.
I bought the joints & bushing.. did all the R&R.. had a local shop do the Press work. Cost a couple bucks, but worth every Nickle.
Many say Lubri-plate grease is good for the Slip Joint splines.
