NOTE:

The ring gear and pinion are serviced in a matched set. Do not replace one gear without replacing the other matching gear. If ring and pinion gears or bearings are replaced, for Pinion Gear Depth Setting. Refer to ADJUSTMENTS . Do not reuse bearings.

Install pinion depth shim behind rear pinion bearing cup.
Install a NEW rear pinion bearing cup with (special tool #C-4310, Installer, Bearing) (1) and (special tool #C-4171, Driver Handle, Universal) (2) and verify cup is seated.

Install a NEW front pinion bearing cup with (special tool #D-129, Installer, Bearing Cup) (1) and (special tool #C-4171, Driver Handle, Universal) (2) and verify cup is seated.
Install a NEW front pinion bearing into the housing.

Install a NEW rear bearing (4) on the pinion (3) with (special tool #C-3095-A, Installer, Bearing) (2) and a press (1).

Fig 5: Collapsible Spacer

Install a new collapsible spacer (1) on the pinion shaft.
Apply Mopar® Thread Sealant to splines of the pinion shaft.
Align marks on the pinion and companion flange and install with (special tool #C-3718, Installer, Flange) and (special tool #6719A, Holder, Yoke).

Install bolts into two of the threaded holes in the companion flange 180° apart.
Position (special tool #6719A, Holder, Yoke) (2) against the companion flange and install a bolt and washer into one of the remaining threaded holes. Tighten the bolts so the (special tool #6719A, Holder, Yoke) is held to the flange.
Install a NEW pinion nut.
Hold companion flange with (special tool #6719A, Holder, Yoke) (2) and tighten pinion nut with a torque wrench (3) to 285 N.m (210 ft. lbs.).
NOTE:
Do not exceed minimum torque 285 N.m (210 ft. lbs.) at this point.

Fig 7: Checking Pinion Rotating Torque

Rotate pinion several times to seat pinion bearings.
Measure pinion torque to rotate (1) with an inch pound torque wrench (2). Measure pinion rotating torque frequently to avoid over-crushing the collapsible spacer.
Pinion Torque To Rotate is:
- New Bearings: 1.9 - 2.5 N.m (17 - 22 in. lbs.)
  NOTE:
  If pinion torque to rotate is low, tighten pinion nut in 6.8 N.m (5 ft. lbs.) increments until pinion torque to rotate is achieved.
  
  NOTE:
  Once proper pinion torque to rotate is achieved, the pinion nut must be staked to the pinion to prevent pinion nut movement.
CAUTION:
Never loosen pinion nut to decrease pinion bearing rotating torque. If pinion torque to rotating is exceeded a new collapsible spacer must be installed. Failure to follow these instruction will damage the axle.

Fig 8: Installing New Ring Gear Bolts
Courtesy of CHRYSLER GROUP, LLC
Position ring gear (3) on the differential case (4) and start two ring gear bolts (2). This will provide case-to-ring gear bolt hole alignment.
Invert the differential case in the vise.
Install new ring gear bolts and alternately tighten to 225 N.m (166 ft. lbs.).
CAUTION:
Never reuse the ring gear bolts. Failure to follow these instruction will result in damage.
Install differential in housing and verify gear mesh, backlash and contact pattern. Refer to ADJUSTMENTS .
