From what I gather, the front bushes are the ones that are prone to fail. The rear mini-donut bushes are not an issue.
They also do the front anti-roll bar bushes. Well worth doing them too. They eliminated the vague, floating sensation.

The rear bush on the wishbone does fail. Most defo.
Usually shows when the car is jacked, the wishbone drops fully to show the bush twisting. If failed it rips...or shows as a rip or split.

May well look into the front roll bar poly bushes. I was looking the rear ones the other day, bolted to the top of the diff. Looks a pain to changed, if they do them for the rear? Dont suppose fronts are the same for the rear?

I suppose failure of the rear bushes is rare in comparisim to the almost guaranteed premature failure of front.  

Front anti-roll bar are "D" bushes. Don't think they are the same on rear.
I was surprised at the difference they made. Didn't bother fitting them at first as I didn't think they would do much.

Have a look at these:

http://www.vauxhall-car-parts.co.uk/acatalog/VAUXHALL_OMEGA_DRIVERS_SIDE_FRONT_SUSPENSION_ARM_-_90576789T.html

Description says "this is a new Vauxhall part". They can't say that if it isn't. Ask them if in doubt.

£23.95 inc VAT.

There is also the option of fitting BMW E34 bushes as a direct replacement for the Boge front pivot bush. This will transform the handling and straight line stability.

The part you need is the E34's upper control arm bush. I have found heavy duty items from Febi Bilstein to be very durable. Meyle also make a heavy duty item, but I haven't tried these..

The Febi Bilsteins on my '99 2.5 estate have now passed two MoTs and still show no sign of deterioration or inside edge wear on the tyres. They were about £10 a side cheaper than Powerflex polys.

These bushes have the same external dimensions as the original GM/Boge item and don't increase road noise by any noticeable amount.

Easiest way to remove old bushes is to knock the rubber part out with a largeish hammer and socket  then cut through the remaining outer sleeve with a hacksaw. When it splits it will just tap out. This is safer than burning them out.

You will need a press to fit the new bushes - a big vice isn't strong enough. I managed with a 6 tonne press. Make sure the arrow on the BMW bush points horizontally towards the centre of the car when fitting it to the wishbone. This will ensure that braking forces are correctly controlled by the plastic insert.

Did the job on my own car a while back and still happy with it...

Got some pics somewhere if anyone's interested.

yes, all possible. There are a few of us on here that have the Meyle heavy duty bushes fitted thanks to Iggy21's research and Mark dtms press and drifts. I have a set in my wishbones.

 Beware the Bmw bushes, i forget the model numbers but some of these give a differant bolt and hence wishbone position as the centre spacer is not central to the bush by 1.5 mill. Not much but enough to upset geometry. I also have a pair of these in my tool box unused.

 But more than that consider the logistics of this operation. The danger is you damage or split a bush or wishbone  in the re fitting/pressing process.  Then your buggered. Car on jacks wheels and wishbones off and no way of fixing the car for work monday morning as the dealers and most factors shut at lunch time on saturday even if they have the parts in stock which they often do not. And if you've got as far as pressing bushes in the first time you do the job, its a good chance it will be well gone lunch time on sat by then.

 In my humble opinion, far better to...
1. Acquire another set of wishbones second hand with good steering knuckles on them and pre press bushes into those first, once pressed successfully,  fit those as a straight swap as the guide on here.

Or 2. Fit new wishbones, Lemforder or what ever as the guide. Then keep your old wishbones, get them pressed with the bushes of your choice ready for next time they fail.

Or there is a third option.
3. buy any  cheap wishbones new, 30 to 50 quid a pair, and press new better bushes into those. Then fit as the guide. This is probably the only use for wishbones from the likes of buypartsbuy or firstline as the bushes in those are shite and will not last 3 months in my, and others, experience.

Its most definately possible to press new bushes. But you need a press of 10ton range (i'm told) suitable drifts that fit the bush to prevent damage to the new items and finding bushes as well all adds to the job. Not straight forward for most people, and not really suitable for a beginner(if you'll pardon the term) who is fitting wishbones for the first time on his drive without a lift or room to swing a torque wrench under the car when its on the ground with wheels loaded.

Says its a new Vauxhall part not a GENUINE vauxhall part as with most parts on this site if they have a letter N or T after the part number its isn't a Geniune VX part.

Thats not to say its no good but you have to be wary with certain pattern parts IMO
