pumpkin removal help!!
Well I I got my 3.75's and bearing kit, so now I am deciding to take it in and have iit all done or do it my self! The corvette shop says it's 8 hours just to swap gears in carrier, so I am thinking if I can just pull the pumpkin myself and take it and the new parts in I will be better off!
Anyone who has done this what is the quickest and easiest way to get out what I need? I have searched old threads and saw one guy did 2 in 4 hours!!! can the pumpkin be seperate from the batwing? Please help me thru this THANKS!!!!

It's easier just to drop the whole rear end out...the trick is to get the car high enough to work on it...a lift or car trailer makes it much easier. The carrier and pumpkin are not that heavy but it is akward though so get some extra hands at that point. Yeah you can pull the whole rear in ~ 3 hours with no problem. Good call on having the "shop guys" do the gear swap....I wouldn't try to swap the ring and pinion yourself unless you've got a few under your belt already. Getting the proper backlash setting is critical for the gears to last.

I just pulled out my 2.59 D36 and swapped out the 'pumpkin' with a 3.07 D36. Myself, a friend and a lift. Not a bad job. We did it in 5 hrs, with interruptions. With a lift and no interruptions figure 4 hours. The pumpkin, fluid, and batwing combined was about 110 lbs, so we just lifted it in and out. I would not even try it without a lift now, 30 yrs ago fine, but not now.

Almost the same. First you have to remove the exhaust, take it out as a complete unit from the cat's back (leave the cats alone). Where he just unbolted the inner tie rod bracket (picture #3) I took the outer ends off and set the unit aside. Then he doesn't mention the C beam, which was a bit of a PITA. Support the rear of the trans and take the two bolts out that secure the C beam to the diff. Reaching the nuts is awkward, but not really bad. Then take the main driveshaft loose at the diff (by moving the rear of the trans slightly up and down you get the clearance to get the ujoint out). If I remember the C beam nuts/bolts are 22mm, 8mm for the ujoint strap bolts, lot of the others are 13 and 15 mm. Hope this helps.
