Measuring castor

[gudge]

Installing drop boxes at the moment in my gq swb. With them in the castor doesn't look quite right. Just wondering surface is castor based on?

what size lift you running and what brand did you get?? what lift are they recommended for? a wheel alignment will tell you what castor you have. i'm no expert but the diff should look upright and not tilted forward.

with drop boxes of any size and any lift your radius arms should be pretty much level with flat ground..

To my knowledge there is only really two sizes of drop boxes 4in "low profile" which will cover you for a 3-5 in lift and the 6in one which will cover you for 5-7in lift..... roughly.


as above, more info needed.

To check your caster is right you will need to compare the angle of the flange plate on the transfer case, either to the rear or the front, to the flange on the diff itself they should be the same to eleminiate driveline issues.
