Which direction removes the passenger side trunnion, please. Clockwise or anti-clockwise.

And is it meant to be screwed tight onto the upright. Mine is very very stiff, I can move it about 1/8 revolution either way then it’s stops solid

Trunnions are handed (they can’t be symmetrical as they set the caster angle) and the threads are also handed (ie one side is LH thread).

What Jim said.
On the grounds that the only silly question is the one not asked, I'll ask it anyway. Have you removed the lock-stop from the top inside of the trunnion?
A photo of the trunnion that you can't undo would be good.

Hi all,

Terry, I had removed the lock stop but that was as good as seized; as it turns out, a sign of the bigger problem.

So I managed to get it undone. Fortunately I had some spare trunnions and uprights, So with trial and error , I worked out the passenger side is left, and from above, is anti-clockwise to undo. Although it was so seized I bent a 3/8 bar with extension trying to undo it.

Eventually undone and discovered the grease had turned almost into solder, gripping the trunnion and upright as one. These were replaced a few years back but when I greased them, it blew the seal from the bottom of the new trunnion so I forgot about it.

I had noticed the steering getting very heavy at slow speed but assumed it was the new wide tyres...

Anyway it was a job I really wasn’t looking forward to. I’ve had the SuperPro bushes for at least 12 months but now I’ve discovered the cracked bushes and seized trunnion, I’m relieved and feel vindicated for doing it before proper failure. :D

Cheers Mike. Good thing you takled the job! Did you do both sides?
Always a good idea to solder the plates into the bottom of the trunnions before fitting.
I use same grease as I use for wheel bearings; TR people say to use thick oil; others say to use gease that doesn't set. Kevin Osborne uses a white marine grease, but don't know the name.
Edit: The grease is RAMANOL WHITE and it is a high quality general purpose lithium grease.

Just done the passenger side so far. I have an agreed curfew with the neighbours of 9.30 pm. At least that’s when the music and impact tools stop :lol:

Off down in a minute to do the other side, quite looking forward to it. :roll:

I did mine years ago I obviously never paid enough attention to the fact they were handed .some jobs you get on with

Well, just finished, new trunnions, polybushes etc.
Coupled with the new springs, adjusted dampers, ride height etc the transformation is amazing. Really light steering , self centres, nothing crashes over potholes.

Chuffed to bits.

Seen better. Can you deflect the inner tube with a bar? If not, then it’s probably ok.

Thanks phil, this is the other arm. Where can we get decent quality rubber bushes, rather than polyurethane?

Phil, they dont flex sideways but do your turn on the centre Bush vertically.
