G55 Pulls to the right - is it the new tires?
Hi,
I have a 06 G55, and added a 2" spring lift and 32" tires. After the installation, I noticed that it pulls to the right slightly. I have read that the solution is offset bushings? Is there a way I can verify this before purchasing them? I have not gotten an alignment yet, as it was not pulling to the left before the lift / tires.
Thanks!

The easiest solution is not to lift your G at all, but if you must . . a few things to check.
Get an alignment. It may have been perfect before the lift, but the change in height will change the distance between the steering box Pitman arm and the drag link arm on the right wheel, thus changing your alignment. Be sure your alignment shop knows you lifted the truck so they adjust accordingly.
Did you replace the two Panhard rods front and rear? Their length is chosen so that at nominal factory suspension height, the axles are centered left to right. Since the Panhard rods travel in an arc with suspension movement, raising the truck height will shift the axles off center to one side. Off-center axles will change the drag link distance per the above and it can also change the thrust angle for your suspension. There are aftermarket parts available that are designed to compensate for this.
Are you experiencing drive line vibrations? Because of the trailing arm suspension, lifting the truck causes the axle to rotate slightly so the pinion flanges are no longer parallel to the transfer case flanges. You may not notice it now, but you will when you have to buy new driveshafts because the U-joints failed. Again, there are aftermarket trailing arms made to compensate for this effect so the flanges remain parallel. Someone also makes replacement bushing mounts for the chassis end of the trailing arms that effectively lower the mounting point to compensate for the change in suspension height, but this is a cut and weld proposition.
Good luck.
