Is there anything to keep the wishbone at the right hight? Ie stop the wishbone working it's way down the bush outer wall. Or the bush sliding down the spacer...?  :-/

[SteveAvfc.]

With regards to the poly bushes where would you recommend that they get purchased from who is the best/better thanks.

Any front to rear movement would be limited by the rear vertical bush especially if it`s a polyurethane bush.

We are talking about the rear vertical bush itself. There's nothing to stop the wishbone working down the bush, or the bush down the spacer. Or indeed up, depending on the forces at play...?

The front horizontal front poly bushes have a lip on the outside edge of the two halves to stop any end float, but as you say, the rear bush will locate that

Should something similar be in place on the rear vertical bush...? Given the leverage involved I also imagine some road grime getting down the edges if it's levered up and down enough...? :-/

I would have though that there must be something to stop the wishbone moving on the bush. I can`t find a decent picture of one but on the Carlton vertical bushes there is a lip on the metal outer casing to stop the wishbone moving so I would assume there is something on the powerflex ones, although the polyurethane would have to be bonded to the metal casing.

Seems like a very good question to me Chris.

There is no metal casing on pollys, and there is no rear Polly made anyway. Hence the one pictured is made by the owner....

Although I would like to be proved wrong, if there is one made that would be good news.

This has been discussed before, and the rear vertical bush has a more complex job than the front, although arguable less stressed, and some sort of ball joint would cover the planes it moves on, however fragile or unsuitable a ball joint may be.

Having cut an oe one in half, apart from the fact it's bonded, there is also a bulb in the centre spacer of the rearward bush, almost ball like.

Sorry Chris, I`ve got my fronts and rears mixed up and I now understand what you`re saying and as you say there`s nothing to stop the bush sliding on the wishbone.

No worries, just curious is all. It might be fine. Certainly would help if the rear diy bush works. I'm sure Razzo would have noticed an issue....

if you noticed in the pic i posted the tube is made up the same length as the one in the standard bush & the poly bush is only a few mil shorter than the tube so it fits well in the mount & there is no vertical movement in the arm or bush. To be honest i have not really seen any great advantages in doing this over the standard set up, mine has both bushes poly'ed & SWMBO's has standard rear bush & poly in the front, there isn't much difference handling wise, so if you asked me would i do it again i doubt it, they have been in a year now & seem fine, but for what it cost you could have bought new wishbones so is it really worth it?

[Lazydocker]

Fair enough... And a nice honest answer considering we were all willing to part with a few quid for you to make them

[twiglet]

Has anyone approached Powerflex themselves about the possiblility of them producing the rear bushes? I see they are adding new applications all the time...  :-/
