trunnion thread

[phillpot]

Could anyone confirm which thread which side?

think its right hand thread drivers side (in uk)

i've thought about this many times and come to the conclusion that a l/h threaded trunnion is best on the drivers side(r/h drive vehicle) and visa versa for the l/hand side.this is purely for a road holding performance point of view in that as you turn left for instance the vertical link trunnion thread will turn down into the trunnion,but this is resisted by the tyres contact with the road surface and results in raising the wishbone and damper/spring fulcrum which in theory compresses the road spring more so keeping the chassis more level.a bit like a clockwork form of stability control.some say it should be t'other way round but this is just my theory.

No idea which thread should be on which side, but as original RH had RH thread, LH LH thread.

Thanks for confirming that

Do the vertical links have the same thread on both sides but the trunions have differing threads? My car has both vertical links with the same direction thread............

All Spitfire and Herald disc braked cars from 62 have "three legged" vertical links - which can't be fitted to the wrong side.

Vitesse/GT6 and Herald drum (OK, plus very early Spitfire and Herald disc) the links can be used on either side. However you must use the right trunnion thread. To be correct the thread of the link and trunnion go with the side of the car.
