G'day Gianni,
Torque settings taken from my S3 manual; figures in pound/foot (lb') for Rover type axles:
Crown wheel bolts 40-45 lb'
Diff bearing cap bolts 50-65
Pinion nut 85
Upper and lower swivel pin bolts 50-65
Hub driving-flange bolts 30-38
Hub driving-flange nut 15-20
Steering ball joint nut 30
Road wheel nut 75-85 (the ones so many people don't bother using a torque-wrench on and causes them grief in the long run!)
N.B. Salisbury axles have different settings to the above.
If a fastener isn't in this list measure its diameter and use a figure from an identical fastener in the list.
Nyloc nuts only need themselves for company. It is a good idea not to re-use them as the nylon locking ring becomes deformed and will not hold as well after being used once. However; on non-safety-critical systems, I re-use them with Loctite on the thread, or I machine off the nylon and use them as standard nuts,
Cheers Charlie
