I just did this last night ,first mark the caps left and right then mark the bolts upper and lower and side then scribe a reference mark from the bolt to cap.loosen it up and carefully roll it out ,the manual I have said to torqe the cap bolts to 60lbs and they matched up almost perfect.i used a socket and jack handle to knock the old ones into the case then used a bit of rtv on the edge of thenew seals and used a sleeve from my ball joint removal kit to hammer in the new ones.
