Nissan Repair: 1988 nissan pathfinder, caster camber, alignment rack

Question
I have a question about the pathfinder suspension. In the factory service manual it says to set the ride height using a "clearance G" figure used to measure the distance between the bottom of the steering stop bumper and a bolt on the frame/lower link. The clearance G is supposed to be 1.6-1.8 inches. There is also another measurement by measuring the length of the protruding torsion bar adjuster bolts. So with it adjusted by clearance G it sits pretty level. But i notice other pathfinders sit noticeably lower in the front. Someone told me that the dealerships set the suspension lower to align it better. Could you tell me if I should pay attention to the clearance G specification or by measuring the torsion bar adjuster bolt? By the way I have the genuine nissan service manual. Thanks for answering this question. I have alot of respect for service techs and appreciate you volunteering your time.  

Answer
Hi Joseph. I usually go by the protruding threads of the torsion bar adjusting threads for a base. Then while on a level surface I take a tape measure and measure from the the Alignment rack or level ground to the center of the wheel opening on each front to "fine tune it" to get it level. With the front end lower the ride is a bit softer. But most people like it level with the rear and generally this adjustment is only made when one side is sitting lower or torsion bars are removed for transmision or clutch service. Just do your right height adjustment before your caster camber as it will affect you camber adjustment. I have seen trucks with a helper leaf in rear and torsion bars cranked tight to fit larger tires and increase tire clearance when turning. But you loose a bit of A arm travel and the ride suffers a bit.  Mike
