I lifted my jeep and had it aligned. they told me that the caster was way off and they dont adjust it at there shop. Not sure what I need to to to correct it.
I installed the Rock Krawler 3.5. Any help would be appreciated. Thanks. Shawn

 

you will need adjustable control arms but i cant see only 3.5 inches of lift throwing it off that much...

 

Where did you take it and get it looked at?

 

Mr Tire, I have adjustable arms.

Just read that alignment page, Going to buy an angle finder tomorrow to check my caster.

 

A RK 3.5 lift WILL throw the castor off that much. It's not that uncommon. Every JK is different. Some roll off the assembly line at the top of spec and some at the low end of spec. I have a RK 2.5 lift and my castor was 2.65L and 2.75R. A 3.5 lift would throw it further out of spec. When you lift a JK, the axle pivots down and back. Not straight down. This changes the castor. Longer LCA's position the axle back to factory spec. Spec is 3.70 to 4.70 on castor. I got a set of RK adjustable LCA's and dialed it in 2 more degrees. Drives like stock. No more flightyness and road wondering. Great investment.
