Question: I bought my 2003 Jeep Grand Cherokee used with a warranty. It's pulling to the right at various speeds. I've had it in the shop and they say they can't find anything wrong. The tires look good, but could they be the problem?

Answer:  Did they tell you it's not pulling, or it is pulling and they can't figure out why? There's a big difference. Believe it or not, drivers have been known to complain about alignment problems that don't exist. This is often because they're driving on a highway with a significant road crown (higher in the middle for drainage purposes); vehicles tend to drift to whichever side of the crown you're driving on. That's why a technician will either find a flat roadway or ride the center of the crown when road testing a car or truck for alignment problems. Even if the tires look fine, there could be an internal defect causing the vehicle to drift to one side, which is easy to diagnose by simply rotating the tires. If the pull is gone, either replace the tire or leave it where you rotated it to. If there's a legitimate alignment problem, verified by setting up the vehicle and taking measurements on an alignment machine, there may be extra work involved on your particular Jeep. Camber, caster, and toe are the three basic alignment angles which are adjustable on a lot of front suspensions. However, the camber and caster angles that have a direct effect on a vehicle tracking straight are fixed (non-adjustable) on 2001-2004 Grand Cherokees. And there have been cases where the cause of an alignment pull is the camber and/or caster angles being out of specification. But Jeep was kind enough to come out with special-offset upper ball joints that allow up to 1.5 degrees of camber and caster adjustment. If your Jeep is really pulling and the alignment angles are confirmed to be out of specification, install the modified ball joints and complete the wheel alignment. It may get expensive, but it's the only way to go.
