Yep, that's it! the bushes stay fixed with the wishbones, and the trunion+bolt+sleeves all behaves as a single assembly, so when you move the upright, the whole assembly rotates in the bushes. That's why it's good to lubricate the bushes generously when you put it together, and even better if you do the lower wishbone grease nipple mod so that you can grease them at intervals.

cheers

I fitted the trunnion last week, I had read the sticky before i did it and its been baffling me all week how the hell the mechanism would work if the bold cannot move which mine did but only when the trunnion moved. So i have it on correctly then. happy days. Will get the other one done on saturday.

The trunnion that I have just assembled seems to work in the correct way but it is quite hard to turn it and it will definatly not fall under its own weight. Is this a big issue? I am pretty sure that as long as it works in the correct way then the stiffness will not matter too much as the weight of the car will make this neglectable.

something is almost certainly assembled incorrectly or needs slight fettling. it may wear in with a little use but it's much better to be free to begin with IMHO

What do you think the problem could be? As far as I can see it is correct and through the greese nipple holes I can see that the bushes arn't moving. There is no resistance when I move the bolt without the nut on. and the torque is pretty close to that stated. Thanks for the help

are the bush kits from qrg known to be good or could they possibly be the wrong length? The bushes and tubes are the same lengths as the ones on the passenger side and that is correct and easy to move, is there I should look out for on assembly a certain order or something?

I had a tight fitting trunnion, well it was so tight that it couldn't move at all after assembly, so used my old top hats as they were in good condition but the flat part was a bit skinnier. I also cleaned down the sides of the wishbone eyes to remove any paint that I had put there from painting.
Loosen the lower wishbone bolts from the lower bracket too so that the trunnion bolt lines up square with the wishbone eyes.
If you are still getting a tight fit then use a bit of sand paper to make the flat part of the top hats a bit skinnier, or a lathe would be easier if you have access to one.
This is what I did and may not be the correct procedure ;)

Is your trunnion new ?? if not then it may have been loose before and worn the brass down although this might not cause a tight fitting

it is a new trunnion as the old bolt had siezed inside, its just wierd that the same kit works fine on the other side. I did the same as you and made sure that the eye faces were clean bare metal. I will give sanding them a go. thanks

the sanding worked. how do you get the greese seal in on the rear of the front 2 bearings?

That needs a bit more explanation I think??? Are you talking about trunnions or wheel bearings?

sorry, the greese seal on the wheel bearings, it is a very tight fit is there any special method?

still no luck, there must be a way to do it

Silly question - they ARE SE6 wheel bearings, aren't they?

I must admit I'm having trouble understanding exactly what the problem is. Could you please describe the grease seal in a bit more detail, and exactly where it's causing a problem?

thanks,
