Polybushing Anti-roll bar bushes WITHOUT dropping the subframe!

[graemewelch]

Is it not accepted as normal that most poly bushes squeek to some extent? I've certainly heard my fair share of reports across many types of car over the years of loitering on various forums.

I always thought (but could be completely wrong) that it was becuase rubber bushes flex more and so rotational movement is taken up by that flex without the bush actually moving, whereas with poly bushes the parts rotate against the bush rather than the bush flexing, thus creating the squeek.



What I've written above probably makes sod all sense anywhere except in my own head!

this also my thoughts but i couldnt be bothered to write it down.

That seems like a bit of a piss poor design oversight by Volvo The only other car I've ever changed ARB bushes on had a bulge in the bar to locate the bush against so it would stay in place, and obviously once clamped down it couldn't move side to side.

Might be a bit pikey, but what about putting jubilee clips around the bar either side of one bush so it can't move?

Not adviseable, as the jubilee clips will rub against the ARB bushes and over time this will damage them.

A washer and then a jubilee clip?

Too pikey for my liking. TBH there is nothing wrong with the OE set up. My understanding is that they should be 'lightly' greased (not with copper slip) with lithium spray grease.

however, I would check with Volvo first as some bushes have 'self lubricating' properties and do not need lubricating. If you do, then the grease you use may react with the bush and cause adverse conditions for the bush to do its job and degrade its performance. Just slapping a load of copper slip on it doesn't cut it for me I'm afraid.
