thanks for replys guys,
I used the triangular plate, reversed/upside down, and tightening the bush bolt to get them in, a method which was correctly explained to me by a member on here. But only after i tried to cheat using a jack and lube to push them in, which did not work, not enough force, more than 2 tonnes needed which is more than the weight of the car.
From memory, the large retaining bolt is not quite long enough to reach the thread initially. So the jack was used to get the bush in a small way. Then tighten the bolt and plate to push the bush in far as poss. But the bolt will tighten before the bush is fully home, so then loosen the bolt and space the trailing arm away from the underbody, i used a combination of 6 and 10 mill Allen keys just placed between, to bring the bush closer to the plate and allow more pressing in before the bolt tightens again, repeat until fully home.
The problem, and i am repeating myself now, is, having tried to cheat in the first place, the original dusted finish on the bush as from the factory has been removed by the silicon grease and so on. This is allowing the bush to squirm out, i beleive. Getting the bush fully home is not a problem. Getting it to stay put once home is the problem now.
So i think i will have to try talken powder as a dry lube as others have said.
I should also add Sp.32 pm'd me as to the effectiveness of the senator bushes, so this thread is as much for him as for me.
Apart from this squidging out issue, which is partly my own doing, they are fantastic, and have/did transform the car from a wayward handfull, to a much sharper animal.
Imho, these components should be mentioned in the same breath as the front bushes, when it comes to wayward handeling issues/tramlining/pulling/constant correction at the steering wheel type problems.
I cant think of any reason why these bushes should not degrade at the same rate as the wishbone bushes at the front.... Anyone?
