Just put my differential back in (not the best job scrabbling under the car).  Wondering what to  tighten up the back horizontal fixings too and also the front vertical nuts....the more I screw these in the more the bushes squish up so not quite sure how far I go?  
Many thanks

I'm sure there are torque settings in the book but I'm at work so don't have it to hand.
The rear bushes are sleeved so it's just "fairly tight" (40lbft?). The front studs in the chassis should have fat bodies with a smaller threaded bit, so the squishing should stop when the big washer hits the fat bit. Then you need them "fairly tight" again.

Thanks for that..the front ones I found bottomed out when the nyloc hits the unthreaded part of the shank. The rear ones seemed to bottom out to with a fairly tight fit..so all good

If your nut is bottomed out on the thread then the component is not held in tightly and will still play around. A nut should never bottom out on the thread.

Do you have the correct washers on the front, which from memory are around an inch and a half diameter and around 1/8" thick?

It was pretty tight before it bottomed out...I do have those washers and using poly bushes too, which are thicker than the rubber ones. It's solid in there. I just turned until I couldn't anymore, which I guess means it's hit the non threaded part of those studs? It's seriously tight, no movement whatsoever.

It should be that the washer has hit the shoulder of the (unthreaded part of the) stud. This is different to the nut running out of thread, which Jon read your earlier reply as stating.

Ah..yes, that's what I meant.
