I have my 84 CJ7 up on the jack stands. Have the plate off the differential housing. Have the gas tank removed. Rear axel is stock AMC 20 with 2.73 Trac-Lok differential. Any necessary maintenance or modifications that I need to think about while she's up in that position? The jeep is basically stock. I have 31 inch tires on her. I plan on installing a 2.5 inch suspension lift, 1 inch body lift and running 33's later on. It'll will be on the highway 80% of the time.
