Bad Day - Diff's dying
Discussion
Well my initial thoughts are that my diff has lost oil and has cooked itself. 😢
It's fine in a straight line, but very clunky on slow speed turns.
I'm going to nurse it to WP on Friday for them to have a quick look.
Options if it's gone, that I can think of.....
1. New complete unit?
2. Wavetrac Diff and rebuild current unit with new bearings possibly cheaper?
Anyone any suggestions or ideas please let me know.

I don't know how this compares to the prices you've been quoted but Holmart have diffs on offer this month (<£900):

Obviously shipping & import taxes to be added as well.

2500 miles later, still strong, even after another drift session
The guys that did mine didn't get back to me unfortunately on which exact bearings they bought, but any reputable gearbox / diff rebuild shop should be able to do it. The only problem was shims, they may need custom manufacturing or at least grinding down a set of regular ones (I think I needed 4 in the end, one ground down to fit).
If it helps get you sorted, I have a spare diff I could be persuaded to let go, it's disassembled at the moment and consists of the following;
Drop me an email if you want it.
Ps. Not saying this to hurry you into a decision, just as fellow owner friendly advice, I had roughly 3 days between when the problem was mild until I couldn't turn any corner without back-shaking banging, here's a handful of videos I made demonstrating the problem;

If it helps get you sorted, I have a spare diff I could be persuaded to let go, it's disassembled at the moment and consists of the following;
- Diff casing = Immaculate
- Crown wheel = Immaculate
- Pinion wheel = Slightly rounded at the tips but perfectly reusable, the rounding will cause a faint whine when cruising at 60-65 MPH but doesn't affect operation, the one I put back in my car had slightly worse rounding and the faint whine is negligible
- LSD center = Absolutely chocolate. Not fit for reuse without major work.
- Bearings = Presuming the metal flecks haven't damaged them, chances are they could be cleaned up and reused, but for the sake of additional 20-30 quid I highly urge you to replace them for longevity and peace-of-mind
- Shims = All missing, scavenged to make my diff
- Bolts = All present and ready for reuse

People never listen.. The Camaro diff is a direct replacement and costs about £800 with gears, diff and housing etc brand new.
Not sure why you would want to pay 150% more for a weaker diff...?

Thanks all,
I'll be ordering a new diff I think and then will rebuild my current diff with a Wavetrac in it. Then replace when I have time.
I have today mastered the art of cornering while depressing the clutch. Which means the diff then doesn't catch. It's not fun, but it got me 200 miles home via WP. So I'm happy, car will sit it out until the diff arrives now.

What about this http://www.lingenfelter.com/mm5/merchant.mvc?Scree...
Seems like I spoke too soon, appears one of the bearings have collapsed, Paul @ MF found this during its service (just goes to show how thorough they are, bravo!);
