Track Arm Bushes

[Chris Scott]

Hi all, 

My RH 3a has the Sierra track arms on the front (at least I think that’s what they’re called!). Does anyone know if anyone does polyurethane bushes for them? I’ve had a quick google and got thoroughly confused!

Yes they do but they're not cheap

Assuming you mean the outer ones (where the ARB fits, originally) then if you can still get them, P100 bushes from Ford are a higher grade (ie. bit of an upgrade) without going all-out on solid poly bushes. More cost-effective upgrade, we did this on our old Exmo.

Poly bush is far cheaper than power flex and offer a range of hardness

Brilliant, thanks all...I'll have a look now

So...on closer inspection the ball joints in the track control arms are worn out...I have a few questions.

1) I assume these can’t be replaced and that it has to be a whole arm?

2) On Burtons the pattern arms say “not suitable for poly bushes” and idea why as I have some poly bushes coming.

Thanks in advance, Chris

The rubber bushes will probably take up more misalignment than the poly ones, but seems odd Burtons make that statement.

I’ve solved the mystery - the pattern ones have the big bush moulded in rather than pressed in. They also seem to have been machined and then sleeved to a different size so the poly ones don’t fit even if you remove the moulded bush (don’t ask me how I’ve found this out...but hasten to say I have a knackered brand new arm )
