Front suspension bushes DO NOT FIT THIS TYPE!!! - Page 7

Really don't think the "torsional" stiffness of these bushes is very relevant

The poly bushes have none , being free to rotate , and the vertical rotation of the arm is controlled by the coil spring and damper far more than that bush . The bush provides location fixing and sound damping . Those of us who have driven with a completely destroyed bush will know you don't feel "unbalanced" !

I’ve read this fascinating thread and a couple of older ones too.
It seems to be a minefield of cheap and nasty parts that are not worth fitting. Some parts are just too cheap and it must be assumed they are of inferior quality.
I too need to fit front lower arm rear bushes but Unipart and First Line seem to have either disappeared or don’t supply. Where to get quality then?
Looks like Powerflex is the way forward. Suggestions welcome.

Do we know the Shore hardness of the rubber? I'm wondering if it might be better to re-cast the bushes DIY, with something like the Belzona 2xxx compounds.

I've had good results on a small scale repairing obsolete vacuum pump mountings by hacking the perished rubber off their end plates, and casting new ones in a carboard mould.

The compounds are expensive, but with chinky-clone bushes lasting only a few K, it might be worth it?

I have mine re-manufactured. Cast in polyurethane.
Use a 25mm bolt with three nuts for the internal hole.
Don't worry about the cut out.
Works perfectly.

And it no harder ride (or ok) Casting polyurethane down the side gaps? I'm going to have to do this with mine as I can't find a Left unipart bush. (polly was Plan A)

I'm glad this thread has been bumped.

I would just like to add the YR2000 OEM bushes have a large gap down the sides.

I also purchased 2 bushes off ebay branded unipart, from the same seller, and they are different. One large gap, one small gap. Annoying both right side!

I agree on the Superflex, I fitted them 2 years ago and have so far had no problem. They sharpen the steering up nicely and I think the ride comfort is slightly better.

To replace the bush, is the best tool a 22mm flexible head ratchet spanner, such as the Silverline 571523 on eBay, item number 182365976633?
Is there a better tool ?

I thought it was an 18mm spanner that was required

Hi Andy.
Your thought is correct 18mm ratchet is good to use once you have cracked the nut, to crack the nut and good knuckle socket is best, or an Aviation spanner modified

MarkS · 2nd December 2018, 22:27

I stand corrected. (M14 bolt head is normally a 22mm).

FYI I want to get suitable tools ready before I jack the car up.

How about a Silverline 656621 18mm flexible head spanner, such as item 182364821115 on eBay.

Is a modified aviation spanner essentially a long ring spanner with a bend to improve access ?

Is there enough access space for a 18mm 1/2" socket, and a universal joint ?

I understand the bolts need to be tightened to 150Nm torque.

Do you have pictures Arctic please ?
