Can someone tell me the torque setting for rear axle half shaft castellated end nuts - Salisbury 7HA LSDiff

Ray

It is a long time since I worked on a 7HA axle but from memory, I did not use a torque setting.

I screwed up the castellated nut until there was no play (in-out) in the hubs, and then backed off slightly to enable the split pin to fit. (good luck if you have wire wheel hubs, this job then becomes really fiddly!)

Then check that the backing off has not given rise to an unacceptable amount of play, if it has then file off the back of the nut to remove material and try again until you achieve a result that seems right. I also seem to remember that there was a fairly large washer behind the nut , you could try using a thinner (or thicker) one to achieve the same result.

Best to check the hub free play after a few miles to ensure that they are still set correctly.

I don't think I've ever seen a published figure so would go with Andyd approach.

Andy is correct when he says there is a flat washer behind the castle nut but for work holding purposes probably easier to file the back of the nut.

Before you bolt the hubs up, check and double check the keys are located correctly in the slots on the shaft. Get this wrong and at best you will distort the surface that the oil seal runs on leading to a leaky rear hub and no rear brake, at worst you will crack the rear hub.
