i just bought new ring and pinion off of a fellow df member. any of you who have been following my chronicles know what i am doing. i am swapping my stock 3.55 gears for new 4.10 and i have one last question. most of the equipment in my diff is pretty new
(only about 12000 miles on it). do i have to replace the bearings and things like that if they are still in good condition? i guess my question is this. do i need to get a full install kit or can i settle for a semi install kit or no install kit at all?
