(17) Add 150 pounds ballast weight to each seat
cushion of vehicle (300 pounds total) to lower vehicle
to specified design height (Fig. 33).
(18) Jounce vehicle several times, each time pay-
ing special attention to release vehicle at very bot-
tom of jounce cycle. This is very important in
allowing suspension to settle to correct height.
(19) Measure and record vehicle’s front design
height. Measure distance between top of Suspension
Height Gage and each frame rail at forward edge of
Gage (Fig. 34). This is the nearest point to the Prin-
ciple Locating Point (PLP) hole.
(20) Compare recorded measurements to specifica-
tions. (Refer to 2 - SUSPENSION/WHEEL ALIGN-
MENT - SPECIFICATIONS)
(21) If recorded height is higher than specifica-
tions, jounce vehicle and remeasure. Before remea-
suring design height, be sure to jounce the
vehicle as described in Step 18. If still above
specifications, one or more rubber bushing mounted
suspension components may not be properly posi-
tioned and tightened. Loosen components as neces-
sary to allow suspension to enter specified design
height, then retighten to specified torque (Refer to 2 -
SUSPENSION/FRONT - SPECIFICATIONS). For
further information, (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - STANDARD PROCEDURE -
DESIGN HEIGHT MEASUREMENT).
NOTE: If loosening the lower control arm mounting
bolts is necessary, be sure the alignment adjust-
ment cams do not turn. The cams must stay in their
original position so the alignment of the vehicle is
not affected.
(22) Tighten shock assembly upper mounting bolt
to 136 N·m (100 ft. lbs.) torque.
(23) Tighten shock assembly lower mounting bolt
to 136 N·m (100 ft. lbs.) torque.
(24) Return vehicle to curb height.
(25) Raise vehicle and remove special tools.
(26) Install tire and wheel assemblies. (Refer to 22
- TIRES/WHEELS - INSTALLATION). Progressively
tighten wheel mounting nuts in proper sequence to
122 N·m (90 ft. lbs.) torque.
(27) Lower vehicle.
STABILIZER BAR
REMOVAL
NOTE: Review all Warnings and Cautions. (Refer to
2 - SUSPENSION - WARNING)
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE).
(2) Remove both front wheel and tire assemblies.
(Refer to 22 - TIRES/WHEELS - REMOVAL)
(3) Remove nuts attaching stabilizer bar links to
each end of stabilizer bar.
CAUTION: Use only Remover, Special Tool
MB991113, to remove link from stabilizer bar. Use of
a pickle fork or other alternate tool will damage seal
and ball joint on link.
