Always put everything together with Never seize Grease because you never no when your going to have to take it apart again. Thats including EVERY nut & bolt. Just 1 or 2 winters with the calscium & salt there using on the roads & nuts,bolts,splines & anything else that is metal to metal can & WILL rust together causing you to use many choice words trying to take it apart. Ever synce I bought my jeep I will go around the jeep when it's up on the lift & just remove nuts & bolts to smear the crap out of them with Never Seize Grease just so years down the road they won't give me a hassel. Not done yet but gettin there. Only have had the Jeep for 1 1/2 yrs.
