WARNING: Never run the engine with one wheel off the ground, such as when changing a
tire. The wheel still on the ground could cause the vehicle to move.

emergency for changing a deflated tire. To avoid damage to the vehicle, never use the jack to
lift the vehicle for any other purpose. Refer to the Owner Guide when using the jack supplied
with the vehicle.
CAUTION: Under no circumstances should the vehicle ever be lifted by the suspension
arm brackets, rear stabilizer or differential housing or convertible cross brace. Severe damage
to the vehicle could result.
CAUTION: Do not attempt to use jack pressure on either the front bumper (17757) or the
rear bumper (17906) of any vehicle. Damage to the bumper covers will occur.
Lift the vehicle using the Jacking Points procedure in this section.

If no improvement is noted, rotate the clamps in opposite directions, equal distances from the best
position determined in Step 8. Separate the clamp heads about 13 mm (1/2 inch) and recheck for
vibration at the road speed.
Repeat the process with increasing separation until the best combination is found or the vibration is
reduced to an acceptable level.
10. Install the wheels and road test (vibration noticeable on the hoist may not be evident during the road test). If the vibration is still not acceptable, install a new axle driveline vibration damper
first, if so equipped. If the vibration is still not acceptable, refer to Section 205 - 02A or
Section 205 - 02B for differential case and ring gear runout checks.
Driveshaft Vibrates 1. Road test the vehicle to determine the critical vibration points. Note the road speed, the engine RPM, and the shift lever positions at which the vibration occurs.
2. Stop the vehicle, place the transmission lever in neutral and run the engine through the critical speed ranges determined in Step 1.
3. If no vibration is felt, balance the driveshaft. Refer to Driveline Vibration in this section.
Traction- Lok® Differential Operation Check
A Traction-Lok® differential can be checked for correct operation without removing it from the rear axle
housing.
WARNING: A vehicle equipped with a Traction- Lok® differential will always have both
wheels driving. If only one wheel is raised off the floor and the rear axle is driven by the engine, the wheel on the floor could drive the vehicle off the stand or jack. Be sure both rear wheels are Klj . 14 ba
