Front Wheel Alignment question 2011 Overland
 
I have a right pull when driving. I took my 2011 GC Overland in for an alignment and they adjusted the rear but said the front caster can't be adjusted. The camber can, but it was Ok. My numbers were 5.2 front left caster and 4.9 front right, which if I remember correctly will give a slight right pull. Does anyone know if the caster can be adjust on my vehicle? It has the quadralift suspension. What should the numbers for caster be?

Caster spec is 5.00. +or- .06,or if you have quadra lift its 5.50 +or-0.6. caster is adjustable, the adjustment is done by loosening the lower control arms and prying.

Thanks for the info. i'll go back to the shop and let them know about the loosening and prying.

And don't let them sell you any parts. There is PLENTY of camber and caster adjustment in our WK2's. I've had to adjust quite a few of these here lately.

For curiosity, what was your camber spec on the front?

Do the quadra lifts have to be in sport mode also when checking alignment?
I have front tire feathering since new and dealer told me alignment out of specs in the "auto" but comes within specs in sport, lowered mode where Chrys says to set them. I dont really understand why to set them in the optional sport mode when vehicle defaults to auto mode whenever started? Do you know if this is correct?

Yes, vehicles with the QL have to be in sport mode before any measurement or adjustmets are performed. The main reason I can see for selecting sport mode for alignments is that the vehicle won't attempt to make any automatic ride height adjustments while in said mode.

Won't this mean that in "auto" (default) mode, the alignment will be out?

Re: Front Wheel Alignment question 2011 Overland
 
I can't give an honest answer on that. I haven't had much time to study exactly how much the QL system adjusts wether it be equal amounts simultaneously with front and rear axles or, how much variation there is between front/rear on different modes.

Doing the alignment in Sport mode is probably due to the fact that even when in "Auto", it automagically lowers to "Aerodynamic Ride Height" over a certain speed. That "Aerodynamic Ride Height" is what it goes to immediately and stays when in Sport mode. So I guess they assume that most of our miles are highway miles.

It looks to me like changing the height of the suspension has to change the suspension geometry at least a little.

My camber was either .3 or -.3 on both sides. I don't quite remember, but I think it was .3.
You say lots of room for caster adjustment? Is it correct that you just loosen the A arm bolts and pry the arm over or back? Other vehicles I've owned always had some kind of cam bolt.

Re: Front Wheel Alignment question 2011 Overland
 
HammFist, I agree. A change in ride height generally affects alignment. As I said earlier, I'm not sure exactly how much each mode will affect our Jeeps though.

Andy, yes, you can change both front camber and caster angles by adjusting the lower arm. Our WK2's don't use ecentric cam bolts like some vehicles. The lower control has 3 bolts that must be loosened. 2 of the bolts are in slots which allow for the adjustment if needed.

Thanks Ratchet, that will be helpful. I have an appt. Friday am.
