Had some minor LSD fitment issues I didn’t realise the other night.
Comparing the diffs, you’ll see the stock open diff has a fair bevel shape below the bearing and speedo gear, the Helical LSD on the other hand doesn’t.

This ended up causing the LSD to rub against the gearbox casing.

So I ended up grinding a bit of the casing rib away and removed a small amount from the speed drive entry.

Then it went back together a lot better, and rotated with minimal effort.

However, after torquing the case bolts up tight

I noticed it’s binding again. Might have to grind a little more away and see if it fixed the problem.
