I’m very disappointed to say that having spent a good deal of time and effort doing my best to rebuild the LSD, I’ve just refitted it tonight and it’s no better.

With advice from Ian and Simon, and a huge amount of help from Robin and Ben, the LSD was dismantled, cleaned, and had its bolts replaced.

The bolts were threadlocked and torqued up correctly, and today I fitted the new sensor and oil.

Sadly though, the knocking noise on the overrun is even more present. Due to its frequency I’d say it’s either the pinion bearing, or just the meshing between the crown wheel and pinion, but in any case, I think the most sensible course of action now is either to hand the unit over for a full refurbish, or to source a known good second hand unit.

Any help on either of these avenues greatly appreciated.
