I really am struggling to understand why you guys are saying they're pressed in too far. They get pressed in from the INSIDE of the wishbone (the side we can't see), so if they weren't pressed in far enough, the sleeve would be sitting even further away from the chassis.
No it wouldnt? The further you press it in the more it moves away from the inside, going closer to the chassis, so when the bush is put in less will be seen!
the welding is also terrible!! very low contact with the wishbone and its just blob of weld!!
and you also havnt explained why the sleeves are bent?!
theyre terribly fitted so everythings just going to come back to that issue first!! lol
get some new wishbones and use the normal sleeves and have them out so only 1-2mm of bush is showing, have them welded in properly and then try!!
fitment is the issue there, they've been fitted with too much bush poking out of the sleeve IMO

I did explain in my previous post - it's because the bush itself is allowing the entire wishbone to flex so much the sleeve is hitting the chassis. This is why I'm saying a longer sleeve/having the sleeve closer to the chassis will fix NOTHING.
You've pushed them in from the wrong side
You pressed them in from the inside of the wishbone because it's tapered and looks logical - but you don't do that you press them in from the outside of the wishbone
It's a b**ch - we had to file the hole tapered slightly to get them started - but that's the way you do it
And you only press them in so far that they sit virtually flush with the bush
Whoever fitted them doesn't have a clue how to do it properly and hasn't welded them enough to prevent movement either
Mine have been in for over a year and done a LOT of track abuse and haven't worn at all
OF COURSE it will - what you've got is 10mm of bush with no casing - that will allow LOADS of movement as the bush itself is quite soft and unrestrained
If the metal sleeve had been fitted properly all the way out to the chassis - then the bush flex would be restrained by the metal sleeve
Thats why the standard mount is sleeved too - otherwise your wishbone will move all over the place
youre saying that the wishbone is being allowed to move so far that the very large and obvious bend in this sleeve was caused by the wishbone?!
that is about 10mm of lateral movement!! something is seriously wrong, if the polyeurethane is there and cased both sides witha metal sleeve inside and out it should not move that far!! i cant see how youre blaming polybush for this, as theyre producing a sleeve of metal and a chunk of rubber, and the same mass produced item has worked perfectly for countless others.
Youve basically come on here and posted pictures of some ruined bushes, fitted completely wrong with bent sleeves and asked us to identify why its gone wrong. and when the obvious is stated by some very knowledgeable people, youve just refused the good advise!!
tbh i suggest you just buy some new wishbones, but some new polybushes, fit them correctly and start again!! because something is seriously wrong there!! you do have the sleve inside the bush present also dont you?! lol
also it would really help if you could take some pictures of the wishbones NOT on the car. if the inner sleve is in place, even if the outer sleeves were a bit too short (which is stand by the fact that they are) there still shouldnt be that much movement to the point of the outer sleeve hitting the subframe, thats a huge amount of movement for a suspension joint!!
isnt the taped sleeve the one you said powerflex took off their line because it caused problems? why are you using it then???
and if using the correct sleeve then it obviously can go out further, because thats how everyone else has mounted theirs!! (and theyre not having these problems)
tbh, i dont know who did that welded, but it is bad!! it doesnt have full contact, its about 80% on the sleeve and 20% on the wishbone, where it should be 50/50, and finally it should be a small line, and not just a quick tac!!
everyone else is mounting the supplied sleeves further out, and theyre having no problems. look at it logially the problem has arose from too much movement of the bush, and youve got a good 5mm of rubber either side of your wishbone allowing extra movement and flex in the bushes!
This is how they should look, with about 1mm of exposed rubber simply to stop the sleeve cutting into the subframe, this means that the bush has no room for deformation and therefore cannot allow the wishbone any latteral movement!!
You do have the right wish bones fitted to your car I take it and\or correct size (diameter) mounting bolt as your nut (pictured) looks completely different to mine. When the bolt passes through the poly bushes inner metal sleeve there is no play?
So you jumped from the supplied sleeve not welded in to the apparantly discontinued flared sleeves that are imo too short.
have you not tired to supplied sleeves welded in?? which is the the recomended way to fit them by powerflex??!
you cen see from this pic, how short your sleeves are compared to how they should be!! perhaps you should tried unflared sleeves welded in in this manner!!
if powerflex are correct and the welds/sleeves are fine, and assuming the batch of polyeurethane wasnt faulty or they would know about it,
then that would mean it would have to be the bolt or subframe flexing to contact the wishbone, which tbh is incredibly unlikely.
As I say, we’re scratching our heads a little as well. From the pictures if just looks like you’ve been getting too much movement in the wishbone wish is causing the metal sleeve to foul on the chassis section. This in turn chews the bush up. It looks like it may be under braking that the problems are happening because of it being the rear bush that seemed a lot worse.
By using a harder material it will allow for less movement, meaning the gap between the outer sleeve and chassis should reduce less because of there ultimately being less movement in the wishbone.
See how you get on with the Black 95 one’s and if that cure it.....looks like it’s back to the drawing board and we’ll have to have a serious re-think.
any chance you can put a pic up of some youve fitted....can see how much bush should be sticking out of the sleeve.....before i fit mine lolfitment is the issue there, they've been fitted with too much bush poking out of the sleeve IMO
The way he has fitted them the wish bones are moving from side to side shredding the rubber bushes as there is nothing stopping them moving from side to side excessively.
The way they are on mine are spot on, is why they are still perfect 3 years on.
Longer sleeves won't stop my issue. Say you look at the wishbone from a birds eye view (so looking at the ground) the wishbone won't be just moving up and down. The force is being applied at the end of the wishbone and thus will be causing it to bend backwards (hence the bent sleeves on the rear bush). Longer sleeves would just make mean more sleeve being bent but perhaps with slightly less severity.
The point no one seems to f**king understand is THAT THE SLEEVE CANNOT GO CLOSER TO THE CHASSIS AND IT WILL NOT HELP IF IT GOES CLOSER. Going closer will just make my problem worse. They're pushed in from the inside because of the taper. I don't blame the workshop that fitted them what soever. They're one of *the* best suspension specialists in Melbourne and prepare countless race cars, I'd like to think they know what they're doing (esp given one of them owned a 182)
Seriously mate - you're a f**king moron
Everyone here is telling you you're wrong - and trying to HELP YOU
There's 4 shots on here alone showing how they SHOULD be fitted with the metal sleeve all the way to the edge of the bush - and you're still arguing saying it's impossible
What do you think we all did - go and make our own sleeves? LOL
I'm telling you how we fitted them - and how the instructions said to - press them in from the inside
I'm not arguing with you - I'm telling you EXACTLY what you did wrong - and so is everyone else - and you're acting like a jerk
lol. Mine where never tak welded eaither and there still spot on after 3 years. Mate you fubard them.
Delivered to me this morning
You've done it wrong
Given that the outer sleeve is made of 22gauge mild steel it cannot provide any form of stability in the suspension in itself. It's only purpose is to contain the poly bush and stop it from expanding under pressure. Even if the bush was expanding I doubt it would cause the damage seen and could not possibly have bent the sleeve the way it has been.
Now lets think about this. In this image of your left hand side wishbone it looks like it has been forced inwards under a great deal of force.

It isn't moving around freely in every direction but being pushed back against the central sleeve that the bolt goes through which has chewed up the bush and bent the outer sleeve.
As already suggested i'd make sure you have the correct diameter bolt, fit it facing the front of the car and also fit the thick shim. Also, didn't another Aussie have an issue with the rear most hole on the subframe becoming enlarged and elongated?
Also, as Fred asked, make sure its VF tight. You have a thick steel sleeve being compressed between a thick steel plate either side by a large, hi tensile bolt. The chances of stretching that bolt are pretty remote unless you use a very long lever or a very powerful impact driver. So get the bugger nice and tight.
If you are still able to move the wishbone in any direction other than up and down after that then I'd say your problem lies with either the wishbone itself or the subframe where the wishbone is attached to it. I'd be tempted to swap the wishbone to rule it out as the cause or at the very least give it a damn good inspection to make sure there are no cracks or splits anywhere but you may need to stress it in several directions to be sure.
If everything now feels solid but the bush still gets eaten then something else is causing the whole arm to give in the direction where the damage is occurring. Given how the bush and outer sleeve are damaged in your pic then like Powerflex said, it does look like your wheel is getting kicked out under hard braking causing a huge and unexpected pushing force on the rear bush and a matching pulling force on the front bush. If that was happening I would expect that you would notice such a harsh impact either from a loud knocking noise or through the steering wheel kicking to left.
This is what powerflex have sent me the other day. You can see they have flared the sleeves and have sent me stronger/stiffer bushes, they said that is a 95 Polyurethane compared to the 80 which is used in the normal kit
