Driveshafts

  • Unbrako 12.9 screws - check
  • Schnorr washers (correct way up) - check
  • Dog bone plates - check
  • Proper grease - check!

Grease in a bag means squeezing it into the joints is slightly less messy than it could be. Bit like icing a cake, apparently.

Having already filled one side with grease and fitted it to the car, I remembered the gaskets... 2nd time lucky, all good now.

Naturally, given my recent form, this was going much too well and my luck couldn't hold. Sure enough:

The stretch bolt into the diff turned out to be rather less stretchy than I'd hoped (sheared when torquing it up - not mega torque, 44Nm IIRC).

Opinion differs as to how reusable these are. Mine turned out to have reached the end of its service life, I think... Replacements ordered from OPC

(Note - I do realise that the "nipple" on the end, needed for the "simplified" diff which unhelpfully self-destructs when you remove these bolts, is unacceptably worn. On my car the diff has been replaced by a Quaife LSD, so the nipples are redundant).
