Which Radius Arm Bushes

[JME_GU]

I've got a 1998 TB45 GU with a 2 inch flex lift. The front radius arm bushes (where it bolts to the front diff housing) are torn and need replacement. Should I use the standard bushes or the caster correction bushes? If so, are there any that you could recommend?

Use only oem standard bushes mate. They will outlast any other bush.

How does that work with the caster correction? Don't I need caster correction bushes to put the front diff in the correct position?

If you need castor correction then yes your only option is aftermarket..
If you get to a 3" lift you can fit drop boxes..

Or for the extream upgrade you can get new radius arms which are made with the castor correction built in and you can use OME bushes

You wont need castor correction for two inch bud. All stock except for springs and shocks. And bias bracket, and sway bar extensions. lol.

Hmm, how much out is it? Id dare say with tow inch it would be two fifths of stuff all of a degree. Nothing standard bushes couldn't handle.
I just dont like castor correction bushes.... the offset bush to me, means premature wear at the thinner section of the bush.

Yea absolutely. I swear the OME bushes are the cause of diff holes flogging out..
But the stock bushes that are in there now mate it on edge.... it was a much nicer drive before..
Allignment blokes say I'm outside the recommended limits.. what it is I've actually never asked..

Another thing too is if the 2inch lift user has replaced the oem spring hats with some cheaper aftermarket spacers which are thicker. This will throw things out a bit more too.
