I need some help here. I built a car thats made for Mod and so I put aluminum diffs in it. The front is an IRS and it is locked and working fine. In the back I have a hardcore racing alum diff and this is the problem diff. right now. When its anywhere near tight it has a tight spot in it. And even when the screw is 100% locked down-it still slips quite easily.
I rebuilt it and checked everything I know, but to no avail.
Do any of you have any experience with the Hardcore alum diff to say whats-up here? Also-it has been carefull modified to accept d-rings-so its not the diff rings slipping.
Thanks,
Ray
I know that when the ae diff thrust spring gets kind of old, it has a tendency to do something similar to what your hc diff is doing...
Also, if it has bushings/berrings, check to make sure that they are the correct dimentions(not too wide, then not enough tension on the diff balls and then sliping occurs)
I don't run Hardcore diff's, but if I were in your position, that is what I would put my attention towards...
