its pretty straight forward, 4 bolts on either side of the axle housing and viola... after u pull the shafts, remove the 3rd member (disconnect 4bolts from driveshaft, rear ABS sensor wire, and 4 bolts for rear upper A arm) then pull the whole member out and set it on the bench, some use different methods, but the important thing no matter how you "install" the lincoln locker is to keep the gears and bears and all parts clean. I use tin foil and wrap bearings gears and everything to prevent spatter from sticking. Then lay in the heat, I melted all the spiders together on mine and then cut 2 pieces of plate to fit across all 4 spiders and welded it to all of them on both sides.... been 2 yrs of wheeling with 33x14x15" Pitbull rocker tires and the only carnage that I have done so far is snapped a front u-joint on the rear driveshaft... it does make an awfully attention grabbing chirp when I go around corners on pavement driving to my wheeling site (imagine an e-brake pulled at 55mph)
