They are pressed fit. Make sure you've got them lined up perfectly.

As Ryano said, don't even bother without a press.

Not all of them are a press fit. Some polyurethane castor bushes are a three piece setup like a normal poly bush.

If that's the case lining them up is just a matter of positioning the front bush bolt hole north in the vertical plane of the standard bush hole, and opposite for the rear. Test fit it first. being poly and easy to install/remove makes it a simple trial/error fit

when doing the second arm, place it on top of the first, with bolts though the bushes to make both arms are aligned.

I haven't ever come across 3 piece setups in relation to castor correction bushes. Not saying they don't exist but I can't see how they would work?
THe single piece ones are moulded to the outer and the crush tube. It allows bush flex while still centralising the arm in the diff mount (Only point of contact between arm and mount being the central crush/bolt tube). The arm itself is 'floating' on the bush and secured via it's bond to the outer ring (pressed) and the inner crush tube)
Personally I wouldn't want to run them. Even the slightest chance of movement is too much for me. Death wobbles from moving bushes in Radius Arms definately aren't cool.

Totally agree. I think Oldmate is referring to some stock castor bushes, not offset/correction bushes.

Nope, they definately exist - I've installed two sets myself (Ironman from memory). They are a three peice nolathane type bush, with four seperate clockings for castor adjustment. No Press required, just a bit of nolathane lube.

Wow, never seen them. I have the same reservations as Ryano with using them.

They do too!
ADJUSTABLE OFFSET CASTER BUSHES
•Three way adjustable.
•High density injection moulded Polyurethane.
•Easier to fit.

Ironman Adjustable Offset caster Bushes are made from a high density injection moulded Polyurethane and laser cut notched Steel Tube. Easy to fit and adjustable to 3 different settings, Standard, 2.5 Degree & 3.5 Degree.
Adjustment is achieved by the rotation position of the inner steel tube.
caster angle is the backward or forward tilt of the differential steering axis. Positive caster is needed in most applications within front suspension in 4x4 vehicles. When a vehicle is lifted via raised springs, this positive angle is reduced. The reduced caster angle will detract feeling and response through the steering wheel. This will also cause reduced self-centring and possible wheel shimmy in extreme cases.
The offset in the bushes will tilt the differential (positive) back toward manufacturers specification thus greatly improved handling and feel. Highly recommended for raised height 4x4`s up to 75mm lift to permanently cure vehicle wonder.

The usual variety:



OFFSET CASTER BUSHES
2° Caster Correction Bushes are available for selected vehicles. Produced from high density injection moulded polyurethane.
Highly recommended for raised height 4x4`s up to 75mm lift to permanently cure vehicle wonder.
2 Degree Caster Correction Bushes are available for selected vehicles.

I'd still go with the usual variety

As said I wouldn't bother without a decent press, rememeber you still have to get the original ones out even if you have 3 piece ones to fit. Get the rubber caster bushes from Pedders, they will give you more flex.

For the 10 minutes of work it would be easier to go to a 4wd workshop that does lifts as they will have a jig and big press to easily do the bushes.

Otherwise it's possible to get them in with a hammer by freezing the bushes, and heating the radius arms in the oven. But you'd have to be desperate to attempt it.

Thank to eveyone with there in put its . The press is not the problem as i work in earth moving the problem i had was to get the holes to line up just not sure were the bush sit in the contol arm cheers !!! mic

when i got my rubber catsor bushes they came with a template so you could position them correctly. i would be asking the person who sold them to you where is the template so i can fit my bushes correctly
