Will any 28 spline ford traction lock diff work in our cars? I am trying to plan out some winter projects. Thinking of rebuilding the extra stock center section I still have from sharon's 373 swap. Looks like I can get used ones from cobras and Mach1's for 25-100$ arround hear.

Any thoughts on this plan? Am I nust/

Shhhhh.....don't tell sharon!
 
Remember used ones should be rebuilt, and the bearings may not be included in the sale price so don't short your budget. Yes 8.8", 28 spline is what you are after. I saw 5 Star had a packadge deal that included gears and bearings from FRP.
 
You should be able to find a used traction lock for less than $100. M-4700-B should be the rebuild kit part number for a used traction lock. Then you should get new seals and bearings for the output shafts from your local FLM dealer. Don't forget at least one new axle nut for the install. Depending how you do the install, you may need both. They are also available at the dealer.

M-4210-B should be the part number for the installation kit which includes bearings and shims for the differential.

There is a difference among 28-spline differentials between IRS cars and solid axle applications. If you get one from a solid axle just remove the circlip from the end of the half shaft that goes into the differential.

You can also beef up the traction lock by adding a friction plate and restacking the clutch packs. You can use the rebuild kit and one of the best frictions from the used unit. Also a stiffer S-spring from a truck application will work better than the stock one.

If you'd like, I have this very informative DVD for working on Ford differentials you can borrow. ;)
 
I have plenty of projects you can do which don't involve your car this winter. Just let me know when you've got the time and the money. ;)
 
I just picked up 2 traction locks from a guy on craigslist for $50. One was rebuilt minus the bearings, and the other needs rebuilt. Keep an eye out for those deals, they are out there!
 
I have been scanning the chicago area mustang clubs for parts for our cars. Found one for 25$ but he lives an hour away.
 
an hour drive is kinda a long drive for a $100 t-loc but if your getting the part for $25 an hour is nothing at all.

I agree, but if you feel the drive is not worth it wait a little longer and you should find one. One will pop up eventually. Besides winter is coming up and that is when a lot of people decide to upgrade parts on their cars. If you lived closer to me i would give you the one i have that needs rebuilt.
 
Umm what is the point of buying a used $100 unit that you need to spend at least another $50 on, when a new one is $216. That is what I bought mine for about 1.5 years ago from rockauto. No rebuilding etc necessary.

So the one I found is from a solid axel. Any negatives to using it on IRS cars?

The only negative is that you won't be installing the "C" Clips because our halfshafts don't have slots(wait for it....) so if you go all General Lee over a bush/river, then you "could" lose an axle. LOL! Just kidding. I guess the only negative would be the 8.8's for the Mustangs are cheaper and easier to find. Wait, thats a positive. :D
