its only about an hour job (start to finish). You might need to whack on the axles to dislidge them if they've never beenr emoved before (Use a mallet or something). You'll know when they come out of the center, then do the other side. Undo the 12 bolts on the pumpkin, leave about 2 or 3 nuts on and have a bucket ready under it, and pry off the pumpkin. (the nuts with keep it from falling) Let it drain, then pull on the floor jack and pumpkin at the same time (dont want the center falling off the jack) until it clears the rear end. Clean up the mounting survaces, put silicone on the rear, place your gasket, then slide the center back on, do up the bolts, slide in the axles nd bolt them back on, fill with oil, DONE..... Very easy. Its just alot of time on your back. The center weights around 75 pound, so be ready for it if it falls, let it go if it does, dont try and catch it and get out of the way, you WILL get hurt..
