Jeep Grand Cherokee WK. Manual - part 65

WARNING: Use welding gloves when handling
heated components.

CAUTION: A bearing heater is used to assembly
some components. Use only an approved heater
and only heat components to 100 - 177 Celsius
(212 - 350 ° Fahrenheit). Never leave components
on heater for and extended amount of time. If
component is discolored after heating, component
has been overheated and must not be used. Fail-
ure to follow these instructions will result in dam-
age.

6. Heat rear pinion bearing (1) with bearing heater

(2).

7. Using welding gloves, install rear bearing on pinion

shaft.

8. Install spacer (1) from pinion shaft (2) with the bev-

eled side facing the gear.

12. Install pinion seal with Installer 9514.

13. Install pinion flange (1) on pinion with Installer

9616 (2). Tap flange on pinion, then thread
installer center bolt on pinion shaft and draw
flange onto the pinion.

14. Hold pinion flange (1) with Flange Wrench C-3281

(2) and tighten pinion nut until torque to rotate is
1.5 to 1.9 N·m (13 to 17 in. lbs.).

DIAGNOSIS AND TESTING

REAR AXLE - C213R

GEAR NOISE

Axle gear noise can be caused by insufficient lubricant, incorrect backlash, incorrect pinion depth, tooth contact,
worn/damaged gears, or the carrier housing not having the proper offset and squareness.

Gear noise usually happens at a specific speed range. The noise can also occur during a specific type of driving
condition. These conditions are acceleration, deceleration, coast, or constant load.

When road testing, first warm-up the axle fluid by driving the vehicle at least 5 miles and then accelerate the vehicle
to the speed range where the noise is the greatest. Shift out-of-gear and coast through the peak-noise range. If the
noise stops or changes greatly check for:

•

Insufficient lubricant.

•

Incorrect ring gear backlash.

•

Gear damage.

Differential side and pinions gears, usually do not cause noise during straight-ahead driving, when the gears are
unloaded. The side gears are loaded during turns. A worn pinion mate shaft can also cause a snapping or a knock-
ing noise.

BEARING NOISE

Bearing noise can be either a whining or a growling sound.

Pinion bearings have a constant high pitch noise, because it rotates at a faster rate. This noise changes with
vehicle speed. If noise is heard under a load, the rear pinion bearing is the source. If noise is heard during a coast,
the front pinion bearing is the source.
