I'm sure that this has been addressed here many times but I couldn't find anything with a search. I hooked up my drive line this weekend on a 49 1/2 ton. The manual says "remove the special square headed plug and lubricate the u joint". My question is what do you lube it with, how much, etc. The manual tells you to add 1.5 pints of 90 weight to the tranny but nothing about what to lube the ujoint with. Any help?
