Got a set of these bushes as part of a rear set, and have swapped them onto a pair of wishbones ready to install.

I notice, however, that with the poly bushes installed the thingies that bolt into the car body now move reasonably freely (you can rotate them round the bolt by hand easily). With the stock metal/rubber bushes on, they only seem to move as far as the rubber lets them i.e. just a little bit, before springing back to the installed position.

Does this make any difference, being as the thingies (bush holders?) are secured to the body, or will there be too much movement at the car end of the wishbone?

I think you just need to tighten up the bolts that goes through the middle of the bush

^^^^^ This

That is the way that poly bushes are supposed to perform, freely pivoting around the central shaft; though there should be a bit of resistance. As long as it's all torqued to spec, and you've replaced the nuts with locking ones it'll be ok.

nail on the head.

Aye, there's a bit of resistance. Easy to move, but not loose - they stay where you move them to if you see what I mean.

Nuts are new and torqued up, so I guess I'll whack them on the car and see what happens.

Thanks folks.

This is also why you have to grease polybushes, I assume? (the sleeve rotates instead of the rubber 'giving' to take up the rotation, so you get 'wear' between the 2 parts unlike in an oem rubber mount)?

That's exactly right.

i must admit i still dont really see how the es bushes work compared to the oem bushes
the sleeve that the bolt goes through doesnt offer any rotational resistance unless you tighten it right up so that there is some friction either side of the rubber
unless i missing something
