Default DIY: Pumpkin Swap

I recently did another 3.5fd w/vLSD Pumpkin Swap, and i thought id share with you guys how I went about it.

CAUTION: Install at your own risk. This is only a tutorial, and I will not resume responsibilty if anything goes wrong with your install.


First: Raise car and place on jack stands


Remove exhaust mid pipe


Remove bottom rear plastic trim pieces





Remove rear swaybar

Lube drive shaft flange bolts and bushing bolts
I used PB Blaster



Lube rear bolt and disconnect wheel sensor harness


Lube axle stub bolts, then remove those bolts
Hang axles with wire or zip ties so they are not just dangling free

Remove drive shaft flange bolts


Place jack under pumpkin and remove pumpkin bushing bolts.
Im using a transmission jack adapter to make it a little easier.
I picked up this adapter @ Harbor Freight for about $40.

Remove rear nut


now lower jack by about 2", then push jack forward just enough for the rear stud to slide out. Now reach around top and you will see a rubber hose clamped onto the differential cover. Disconnect [dont cut unless you have a replacement hose] that hose [sorry forgot to take picture of this step]. Then you can completely lower the jack and remove the pumpkin.

Install is the Reverse.

TIP for Install: raise pumpkin in place with rear stud in its hole, then install bushing bolts and install till hand tight. Then hand tight the rear nut. Then torque the bushing bolts. Then torque the rear bolt. Going little by little like this ensures a smooth install because alignment wont give you any hassle.

Nice DIY, I did a pumpkin swap a few years ago, wasn't that bad but this certainly helps.

Thanks! This made the swap super easy!

Hardest part was getting the bolts in while holding the new one up.

I skipped taking the sway bar off - plenty of room with it on.


What a difference! No more one wheel wonder for me - i wouldn't of guessed what extra pull it would have. I thought i was very good at feathering the gas and getting the car to accelerate with limited wheel spin but lsd is the way to go!
