Thanks for the pointers guys
Decided to use associated damper oils seeing as they seem to get fairly consistenly good reviews (and I've got a couple of half bottles from a mate to try - got to keep the costs down where I can

).
Will probably also go with the associated diff/moly greases as per the other thread on here.
Re threadlock - yes, the Durango stuff certainly seems to work well! Is it plastic safe though
I've also got a good selection of the 'usual' loctite threadlocks in red/blue and purple so should be well covered on any metal to metal duties.
