It's fairly easy. jack up the truck, undo the two bolts on the lbj bracket and the lower control arm will be separated from the spindle. (Suspension will obviously be at full droop). Then remove the cotter pin and the lbj bolt, and use a puller to pop the ball joint/bracket loose. Take off old boot and install new grease and boot after cleaning the joint.Any idea how hard it is to install a new ball joint rubber cover on the LBJ?
