B44.2 slipper issue.

[Hog]

After yet another rear diff failure a week ago, time came to do something about it.

I've rebuilt the diffs with new balls and thrust races and shimmed them correctly (even a little on the tight side at 7 & 2 rather than kit suggestion of 6 & 3).

Racing on Wednesday evening another issue came to light which could be the cause of the failures though - and that's the slipper adjustment, or lack of it.

Even with the adjustment nut backed off as far as it will go so it's touching the forward drive cup, there is no slip from the slipper. If I take the assembly out of the car I can make it slip reasonably easily, but back in the car - nothing. Even when out of the car there is perhaps only 1/2 to 1 turn of the adjustment nut from some to no slip. Nothing is binding in the car, and I've taken the whole assembly apart, cleaned it and rebuilt as per the manual.

I even took the slipper assembly out of my other (used once since new) B44.2 and that's the same. The B44.2 manual says there should be a 2mm gap between adjustment nut and forward cup, but that just locks everything up solid.

Surely this can't be right can it? Do I need a shorter softer spring to give me a better range of adjustment? Or do I have something fundamentally wrong?

At this stage I'm even considering going the route of B44.3 diffs once I've exhausted my stock of B44.2 diff parts!

Thanks in advance for any advice!
