Jacking the Vehicle
!
DANGER
For your safety and safety of others, a jacked vehicle must be
supported properly with jack stands before working under and
around it. Also the wheels on the ground must be chocked on
both sides to prevent vehicle from rolling forward or backward.
1.
Secure vehicle for maintenance. See "Securing
Vehicle for Maintenance" on page 25.
2.
Loosen the lug nuts on a wheel being removed
approximately 1/2 turn counterclockwise while it is still
on the ground.
3.
See important note above. Place proper jack under
vehicle as follows:
a.
Front tires: Refer to Figure 6-1. Place jack under
body frame where the A-Frame struts attach to
the body.
b.
Rear tires: Refer to Figure 6-2. Center the jack
under the receiver hitch.
4.
Jack vehicle only high enough to do the work
intended.
5.
Support vehicle securely with jack stands before
working under or around the vehicle.
6.
Work may now be performed on the vehicle. Be sure
to properly torque all bolts that were loosened. Wheel
bolts should be torqued after vehicle is lowered to the
ground.
7.
Lower vehicle by first jacking vehicle up high enough
to remove jack stands. Then carefully lower jack until
vehicle is on the ground.
8.
Remove wheel chocks.

Shock Absorber Adjustment
Traveling fast or carrying heavy loads may cause shock
absorbers to bottom-out making the ride rough. The
mounting position of the rear shocks is adjustable to
increase or decrease firmness of ride. Typically, they are
set soft for slow speeds and light loads. Fast speeds and
heavy loads require a firmer setting.
Adjust rear shock absorber position as follows:
1.
Refer to "Jacking the Vehicle" instructions to jack
vehicle up before repositioning the rear shocks.
2.
Refer to Figure 6-3. Locate shock absorber’s top three
mounting holes.
