Here at Quigley Motor Company we offer two different types of 4x4 systems. The first is the solid axle 4x4 system that is standard on all Ford vans and all vans previous to 2003. Since 2003 we have introduced our Independent Front Suspension (IFS) 4x4 system which is standard on all GM and Chevrolet vans since 2003. We did offer both types of 4x4 systems on our GM and Chevrolet products up to 2006, however in 2007 all GM and Chevrolet vans are manufactured with our IFS 4x4 system. Our Ford products have always been a solid axle 4x4 system.
What to know and understand about the alignment of each type of system. The IFS is aligned to GM / Chevrolet 2-wheel drive OEM specification. For any solid axle application it is best to have the alignment center contact Quigley’s and supply us with the last 8-digits of your VIN.
A solid axle does not usually require an alignment unless you have a hard impact which would cause a component to be bent. A solid axle does tend to have more tire scrub or wear then independent suspensions, this is an inheritable trait. This is the most important reason for rotating your tires, see Tire Tips for more information on rotating your tires.
Both systems should rarely require an alignment. A pull or drift when braking or driving doesn’t necessarily indicate an alignment issue. Also excess tire scrub or wear isn’t indicative of an alignment issue. If you notice any of these concerns please see Simple Inspections under Tiger’s Tips. Or have your local service center perform a simple inspection of your vehicle.
If you have any other questions or concerns please contact us. If Tiger is out we’ll have Pooh contact him; he’s probably out bouncing, that is what Tigers do best.
