Default 8.8 Build Questions

I am building up an 8.8 to put in my 97 SS.

I am going to get an 8.8 Housing with a 31 Spline Carrier, 31 Spline Moser Hardened Custom Axles, and 4.10 Gears. I am going to cut the tubes from my 10-bolt and have them welded to the 8.8 center.

My question is: If I get a 1995 Mustang GT 8.8 Housing with ABS, will any year carrier work with this or are there specific years I have to stick with?

I want my ABS to work still because this will be a daily driver I just need to know what components work together.

If you have 3-channel ABS, you're going to need to figure out a way to duplicate the function of the ABS reluctor sensor/gear in the stock 10-bolt. It's a sensor mounted to the top of the differential housing that reads pulses from a toothed ring on the carrier. I don't know anything about Ford 8.8" rears, but I highly doubt they use the same method for communicating ABS information.

If you have 4-channel ABS, all you need to do is reuse the stock ABS sensors on the stock rear wheel hubs.

Limited slip is the same as posi-traction.

Ok cool, so I found a 31 Spline LS Carrier from a 99 Cobra, and a 95 GT 8.8 Housing. Will those work together?

Just talked to midwest mustang in Lawrence, Kansas and they said that the 99 Cobra Carrier will work just fine in that 95 8.8 and I am getting it all, 8.8 Housing/31-Spline Carrier/4.10 Gears, for $400.00 shipped!

Should work fine. They are physically the same rear ends. I think the rears on the SN95II's were the same length as the SN95's. Shouldn't have a problem. As for welding your axle tubes on the pumpkin.. I would just weld on perches for the shocks and relocate the spring perches (if need be, which I'm sure). Keep the 8.8 as complete as you can.

To do that I have to use the mustang brakes, and the axles are shorter so I either need new rims to adjust for the length, or wheel spacers...which I would prefer to NOT use spacers.

Believe it or not you should be able to "pull" the tubes out. I'd take both housings to a qualified driveline shop and tell then to swap the tubes....they shouldn't have too much of an issue doing it.

Unless they made the axle tubes in different diameters, which I doubt but could be wrong, you will not be able to just pop out the axle tubes and pop the 10 bolt tubes in. They are different diameters.

The 8.8 is 2.8" and the 10 bolt is 2.66". It doesnt seem like alot but it is. Easiest way to do it is the collar/sleeve route.

I am planning on having custom bushings made to compensate for the smaller diameter tubes

1badzee is right. cut the old mounts off and weld them to the new rear. why does everyone want to use the 10bolt tubes? doesnt make sense to me. after making a jig, takes all of 30 minutes to transfer the brackets. word of advice, use the 8.8 tubes, cut them off at the end, use 9in ends and press the larger bearings onto the 8.8 axles. you will have to machine the axle because it is slightly larger in diameter than the 9in axle. you then have bolt in/semi floating axles. no c-clip eliminators necessary

I have to assume that the reluctor ring cannot be applied to the Ford carrier? Has anyone devised a solution for this? I'd also consider the 8.8 rear but would also like my ABS to work. Is it possible to convert from the 3 channel to 4 channel ABS?

I say get different rear wheels and keep the 8.8 as unmodified as you can..

The axle from a late 90's mercury gran marquis is only 1/2in. narrower (1/4 in. on each side) than a stock rear end.

The 8.8 OD 1s 3.00 and the 10 bolt OD is 2.62.
The 10 bolt tube will fit inside the 8.8 tube with about a 1/16 in to spare. a collar/sleeve isnt needed.
The wall of the 10 bolt is actually thicker than the 8.8.(wish I had taken that measurement. Just looking at the cut ends and you can see it.)
