8.8 Rear end Install help

Hi All, I just bought an 8.8 rear end with 4:10's to replace the stock 7.5 in my 04 V6. The 8.8 came out of a 2000 GT Deluxe so I've heard it's a direct bolt in.
I've never changed out a rear end before so if anyone out there can tell me how to do it I'd be very grateful. Thanks All !!! Dale (aka) Hellish Horse

Literally just unbolt your 7.5 and bolt the 8.8 in.

Re: 8.8 Rear end Install help

I believe 87-98 should all fit. You can also use one from a Lincoln or several other cars.

Re: 8.8 Rear end Install help

If the shop supplies the 8.8 posi rear end it will probably be out of a stock GT & have 3:27 Gears & cost you a minium of $1200. Do it yourself alot cheaper. You would still have to upgrade your gears for quicker acceleration.
I would have went with 3.73's if this rear end didn't come with 4:10's.
Gonna try the 4:10's out to see what they're like before I go changing them.

Re: 8.8 Rear end Install help

1200? LOL better be fully built with 31 spline axles damn

fourloko530, stick with 94-98 housings to make things easier, otherwise you'll have to pull the axles out of the older fox housings and swap in your own since the fox cars are set up for drum brakes and 4 lug (yes the 7.5 and 8.8 both have the same 28 spline axles from the factory)

I have an '01 GT 8.8" in my '94.
99-04 8.8 will fit 94-98, and are a little wider. When I added my 17x9 '03 Cobra wheels they now sit flush with the quarter panels in the rear.

Re: 8.8 Rear end Install help

Re: 8.8 Rear end Install help

The junk yards around here charge $500 & up for an 8.8 out of a GT & you have to remove it yourself.

Re: 8.8 Rear end Install help

Never said they weren't rip-offs!!! I agree...that's why I waited til I found the right one for the right price on Craigslist. Waited about 6 mo.s but got it for $300 which I figure is a fair price.Look at the Mustang rear ends on Craigslist in phx area. You'll see what I mean on the prices. There's guys asking $750. Just "NUTS" !!!

Re: 8.8 Rear end Install help

Well All....It's been fun just B.S.n' but I was really hoping someone could tell me in which order to unbolt things to remove this rear end without the springs popping out before I'm ready for them. Going to use floor jacks to hold the springs til I'm ready to let them loose if possible. Don't know if my plan of action is right or not but here's my plan.
1) Jack up car & remove wheels
2) Remove Brakes, Calipers, Rotors, etc.
3) Remove Driveshaft
4) Jack under Springs
5) Disconnect Upper Control Arm from Axle Housing
6) Disconnect Shocks
7) Lower Jack to Release Springs
8) Disconnect Lower Control Arm & Remove 7.5" Rear End.

***Like I said...Never done this before. Nobody replied with any info on the subject though. Any help is still much appreciated !!!

That should work just fine. I normally pop the lowers loose first to go ahead and get the springs out.

The calipers you can leave connected to the brake lines and just hang them inside the fenders
