The 1996 Nissan Quest Alignment Specs
Making sure that the wheels are aligned correctly on your Nissan Quest is important for many reasons. Correct wheel alignment helps to prevent uneven tire wear. It is also necessary so that the vehicle tracks straight and true down the road, without pulling or wandering from one side to the other. The three angles of wheel alignment -- caster, camber and toe -- have specifications for the correct settings.
Caster
Caster is the forward and backward tilt of the upper control arm or strut in relationship to the lower control arm. If the upper suspension component tilts forward, it has negative camber. If the upper suspension component tilts backwards, then it has positive camber. Camber, like other alignment angles, is measured in degrees. The 1996 Quest caster specifications call for a positive camber range of 1/20 to 1 11/20 degrees, with the ideal being 4/5 of a degree of positive caster.
Camber
Camber is the tilt inward or outward of the wheel in relationship to the center of the vehicle. If the wheel tilts outward at the top, it has positive camber. If the top of the wheel tilts inward towards the center of the vehicle, it has negative camber. The range of camber can be from 9/20 to 1 1/20 degrees positive. The ideal measurement is 3/4 of a degree positive.
Toe
Toe is the relationship between each of the wheels in relationship to the center line of the vehicle. If the front of the wheel tilts inward, the toe is negative. If the front of the wheel tilts outward, the toe is positive. Each wheel has its own toe measurement, in addition to the measurement of total toe, which is the sum of the toe from both sides. Toe is also measured by how many inches closer the wheels are in the front of the tires than the rear. The correct setting for the Nissan Quest is 0.08 to 0.16 inches toe-in.
Adjustments
Caster and camber settings on the Quest are not adjustable. If caster or camber are out of specifications, you will need to replace the components that are causing the problem with the suspension. Toe is adjustable by turning the sleeves on the tie rods in the correct direction.
Rear Alignment
The angles on the rear are the same as on the front, except there is no caster measurement. Caster is primarily a measurement concerning turning and since the rear wheels do not steer, caster is not applicable. The rear wheels should have a camber measurement between minus 1/4 degree to 1/4 degree. Rear toe should be from minus 0.16 degree to 0.16 degree. Rear camber is not adjustable, but the toe is. If the camber is off, replace the components that are responsible for the incorrect angles.
