the originals failed the mot and the car was very loose at the back, so i changed them for senator items to firm up the ride and accuracy of the car on motorways, which worked a treat.
But the wayward feeling has returned and on inspection noticed the bushes where no longer fully home. There is a 5 to 7 mill gap around the lip of the bush to the trailing arm. This may be due to me using silicon grease to get the buggers to go in, as the fit was very tight, and i have since thought talcon powder may be a better bet, as they are covered in white dust from new. Any thoughts on how to stop them squidgeing out again?
Cheers
Chris.

take them out clean with a solvent and reassenble dry chris :y
-
remove that grease and put them in dry. Usually that why some ppl use a press or lower the car onto the bush using a trolley jack and a concrete block with a bit of wood on top. real technical i know ;D
-
i had a jack to push them in with, it lited the car off the ground and still did not go in. So used the triangular plate upside down and screwed the bolt in with an air ratchet to force them in. But i think i am going to have do it all over again by the sound of it... Arse!

You could try coating them in washing-up liquid, after cleaning the grease off.

ill give you a lend of the mother in law, the car will never lift then ;D ;D

That sounds like what has gone on my estate. So DONT use a grease to get it in then? :-/

No, no grease, i used silicone grease to protect the rubber, as some rubbers deteriorate with petrochemical based lubricants. Oil seals etc are ok obviously but no reason i could think of why bushes should be "oil proof" so to speak.
As far as lubeing the bushes goes with reguard to easier fitting then no, DONT. The cup in the trailing arm is painted(on mine at least) in a nice glossy shiny black paint and the bushes are wedged in and if lubed will "squidge" out once what ever tool to press them in is released. I had to remove and clean off the grease, then refit.
It seems i did not clean them off well enough and they have come away a little again. The bolt and triangular plate which holds them hold the centre spacer in position, this cant move with the centre bolt and plate fitted, but the give in the bush rubber, i imagine, has allowed the outside cup to move south out of the cup to a point the rubbers stretch will allow. If that makes sense?
Ill have a look when it stops lashing down. Hth

Yeah thats great. Many thanks :y

Is she up to pressing in front wishbone bushes? Only 6 ton required IIRC. :P
;)

But pushing the old ones out is more like 60 tonnes - several mothers in law.. ;) :D
-
I was thinking Chris, couldn't you rig up something with a pair of spring compressors and pull them in slowly a turn at a time :-/.
Just a thought :).

CHris I've used brake fluid its a rubber lubricant that doesn't destroy rubber just be careful of paintwork :y :y

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?
-
Well the rear bushes are not fluid filled like the front ones!
Anyway, I also had issues fitting them and the plate method would not work for me so I borrowed (cough, and still have), the proper tool for fitting them :y

A correct tool? Do vx have a mother in law on the omega tool shadow board? :-)
Tell us more....

I will post a pic this evening...

thanks Mark, much appreciated. Any thoughts on the lube/talcon powder thing?

Soap is an option (not washing up liquid)

ar yeah, :y i remember hunting round the garage for something with a hole and a diameter to reach the outside edge of the cup. Didnt have anything of that thickness/strength to even make something up.
So pull the arm down, u shape to the back of the arm, and tighten the bugger in, is it a fiddle to get a spanner on the back/top nut to stop it spinning round?

No, easy enough as the arm can be dropped 1-2inches.
You have to pack the bolt out with spacers and washers as the bush is pushed in or the bolt fouls on the chassis

i see....cant find one readily available on the net from kent-moore/lazer or the like, but fell upon this for front wishbone bush alternatives some of the links are clearly those you pressed for me from merle, do you recognise any others as being of any use...maybe? :)
maybe i should start a new thread with this link http://www.cadillacforums.com/forums/cadillac-catera-cimarron-forum/137056-aftermarket-suspension-bushings.html
