Will be replacing my front anti roll bar bushes soon (sport suspension 33mm roll bar) - thinking of Powerflex poly bushes despite the fact they're twice the price as oem.
Worth the money ?
Do they squeak at all ?

Cheers

I think you're supposed to put silicone grease inside the bushes where they meet the bar, which will stop them squeeking.

 

+1 what Mark SF said!
The workshop manual tells you to do yo as well. A couple of weeks ago I replaced them too, but with the original OEM bushes. With grease, no squeaking so far.

When doing a full front suspension rebuild, I'd make the choice Polybush or OE throughout. However, for a partial replacement I'd stick with OE.

Thank you all - I've just replaced lower wishbone ball joints, and bushes in oem stock fittings, so maybe I'll stick to oem on the roll bar...

 

What procedure did you use for the lower balljoints?

 

I bought a cheap scrap set of wishbones off Ebay so I could work on them at leisure without having the car off the road (its my daily driver), as well as a set of XJR springs/pans which I refurbed.
Aside from the usual cutting of the ball joint lip I used one of those big c-clamp ball joint kits to press the old out and the new in - still required an extended breaker bar. I had a garage press in the bushes as I couldn't get them in straight and buggered one up, only charged me a tenner.
I was going to change out the lot myself and even made the compressor tool, but I'm getting on a bit and didn't have the confidence to do it so got my local indie to do the work as well as the track rod ends - £350 including tool hire/alignment all in. The original ball joints were shot and beginning to eat the inner tyre walls so had to be done.
The car feels a little more stable/tighter and the steering lighter and more responsive.
I'm married to this car now.......

Regarding the springs I did post a while ago about the ride height on changing to the lower XJR springs, someone commented about the extra stiffness negating the lowering "effect", and I can confirm that the ride height at the front is virtually no different to the original set up. I did have new rubber seats fitted of course....
