Section 3 — Front Suspension
See chassis data information for clearances and assistance in calculating trim heights.
Since there is a large variation in completed vehicle front weight due to differences in body weight and equipment, care must be taken not
to exceed the GAWR/GVWR. Also, the front suspension alignment must be checked and reset if necessary after the vehicle is completed.
Caster and camber should be set with reference to the "A" dimensions.
See The G Van Service Manual for complete alignment procedure, specifications and measurement of the "A" dimension under "Diagnosis
and Front Alignment" section.
Section 4 — Rear Suspension
Due to differences in body weight and equipment, care must be taken not to exceed the GAWR/GVWR.
Clearance to body should be provided for the suspension, axle, driveshaft and tires under the following conditions: (1) Axle in full jounce
against the metal-to-metal stop, (2) Axle at 4.5º roll with one side of axle in full jounce at the metal-to-metal stop and (3) Axle at design
position. Allowance for the tire chain clearance shown on a maximum grown tire must allow for (1.66 in.) clearance to the sides of the tire
and (2.5 in.) to the top of the tire. Be sure sufficient clearance is provided for suspension, axle, and tire and wheel through full vertical
travel (up and down).
Pipes, wiring, conduits and any other related components must not be placed where they cross the path of motion of the rear axle, driveshaft,
axle brake pipes, hoses, spring or tires. Such crossing could result in rupture, wear-through, or separation due to normal axle motion.
NOTE: Notification to the consumer may be required in certain states if tire chains cannot be used.
See chassis data information for additional clearances and for assistance in calculating trim heights.
