Question Need to rebuild my limited slip, have questions??

So my rear end is chattering when going around a corner at low speeds. My guess is that the clutches in the limited slip are going bad since the truck has 128k miles on it and I've never changed the fluid.

I have a few questions. Does anyone no the ford part number for new clutches and what not are needed? Is there any aftermarket company that sells them? Is there a how to on the forums or and procedure to rebuild my limited slip?

Thanks

Honestly I would scrap it and get a Detroit soft locker. Much stronger and will handle the abuse that a diesel puts on stuff. I would never do a clutch system ever again. I want to know if something starts to slip it will lock. They still unlock in turns so your good there.

I would but the cost of a soft locker vs rebuilding mine? I only put about 1000 miles on my truck a year.

IF you really only drive it that much I would change out the fluid. Then see if it runs right. I mean if you only really drive it 1000 miles a year it is not a huge problem. IF the clutches go completely it will just do the one wheel peel.

I just bought my truck with 216,000 miles on it and the previous owner said other than the engine oil he never changed any of the fluids. to be sure i changed it out, but my limited slip still worked fine. i would think some fresh 75-140 and some friction modifier might help it out.

I would change it out no problem. Just make sure you don't add friction modifier to a fluid that already has the friction modifier already in it.

I cant remember exactly how to do it but in the dana rears there is a method for taking the clutches and rearranging them in a different order and it will restore the bite of your limited slip. With trial and error i remember you could change how much it locks up.
