    Castor Correction - swivels or radius arms

    Hi,

    Having now lifted my 90 about 3 inches I need to correct my castor, thats now sitting at about -1 deg. I have already fitted both front and rear d/c shafts to get rid of most of the vibrations. I don't wont to really move the pinion angle from where it is now as it suits the d/c shaft fine - making corrected swivels the best bet. However the front springs and shocks are sitting on a fair angle as the diff has rotated foward so I wouldn't mind correcting this also - making radius arms the go!

    Suggestions??

    Various places in the UK ( Buy a UK LR mag to find out) sell castor correction bushes for lifts up to 2.5 inches.
    Next stage is a new set of cranked and lighted radius arms. Finally, Disco White has successfully machined a set of swivel balls.

    How much you got to spend?

    I guess the answer lies in how you want to deal with your propshaft angles and remaining vibration free. I would have thought swivels and then run a DC front shaft.

    bend the radius arms as well. its free. you can even do them cold.
    cranked radius arms (2 bends in each arm) allow the bush at the chassis end to sit neutral and can help with caster. however i would still get caster checked and adjusted as necessary.
    its funny seeing people drive radius arm equiped vehicles around lifted to the max, you can see the chassis end bush has no down travel left

    Wouldn't this end up shortening the radius arms considerably, thereby drawing the axle rearward and shortening the wheelbase, pulling the spring seats out of alignment, etc. even more than lifting has already done? The companies I have seen that offer castor corrected radius arms in the US also lengthen them, correcting the axle position for lift as well, thereby maintaining the axle position.
