Castor Angle advice ?

Just had the alignment on the WJ done, and all good apart from the Castor angle. I am suffering a slight drift to left on jeep for sometime.
Factory says between 6.00 and 7.5 degrees, and is non adjustable.

Mine is approx 5.3 degrees on one wheel and 5.5 degrees on the other.

1) Is this something I should be concerned about ?
2) What would cause this if its not adjustable, worn control arm bushes ? (just guessing here...)
3) Any chance this would cause "slight" to the left drifting ?



Thanks

Re: Castor Angle advice ?


The caster is a preset value which normally can not be changed. Play on the upper and lower ball joints could change the angle a bit. The caster angle is there to for directional stability. There are ball joints available with a slight ofcenter which allow some adjustment of caster and camber. Donīt know if this will do anything to the slight drift you see.

Re: Castor Angle advice ?

They make a standard factory equivalent ball joint and then there are some designed to adjust the caster angle, usually needed for big lifts or other mods. Perhaps someone installed the wrong ball joints? Otherwise I'd have to say yours are bad and need to be replaced with the factory spec ball joints. Sounds like you need a through inspection of your front suspension to determine what components are causing the improper caster angle.
