I installed a set of 8 Teraflex control arms, set the caster to 5.5 degrees but now the Jeep darts around on the freeway. Has anyone else experienced similar problems? Any suggestions on how to fix it?

 

you need to adjust your caster a little more

 

Which way? I'm curious too.

 

are you sure you added positive caster and not negative?? 5.5 of negative caster will really screw you up. positive caster will have your pinion dropping to the ground.

 

this should help you out

awh, I didnt catch that....

 

Positive 5.5 degrees, pinion is pointing down (not up)

 

Generally, more caster tracks straighter, but has slower turn-in.

Darty handling is merely excellent tun-in.



So, generally, you add positive caster to reduce dartiness.



Plan B - if the dartiness is in response to the suspension compressing/extending, as in reacting to bumps, then its more likely bumpsteer than caster at play.

 

Lengthen 2 turns, report back.

 

I will give this a try this weekend, thanks.
