One trunnion has a right-hand thread and the other trunnion has a left hand
thread. Unless you are a real butcher you will not fit them on to the wrong
vertical link! I have never heard that they have different dimensions,
although I believe that they have been re-manufactured by different
suppliers to service the spare parts market.
When the steering wheel is turned this 'handedness' means that one vertical
link is screwed into a trunnion, and the other one unscrews. I have seen
various reasons for the left / right hand threads over the years, one of the
more interesting theories (though not necessarily the correct one) is that
this is deliberate to compensate for the lean of the car as it goes around
the corner (a self-levelling device). I don't think the amount though -
maybe 0.5inch at the most - would be enough for any real effect bearing in
mind the compression of the springs etc. Anyone have any other thoughts?
When you have them fitted don't forget to give them a good lube using EP90
gear oil through the nipples and at regular times in the future.
Cheers
Pat
