Differential: Service and Repair
DISASSEMBLYNOTE: The differential is serviced as an assembly. The only parts that are serviceable within the differential are the differential bearing cups and cones. If any other part fails within the differential, you must replace the differential assembly along with the transfer shaft.
The transfer shaft should be removed for differential repair and bearing turning torque checking.
1. Remove the differential cover and bolts (Fig. 174) (Fig. 175).
2. Remove the differential bearing retainer and bolts (Fig. 176) (Fig. 177).
3. Using a plastic hammer, remove extension housing/adapter plate on the right side of the transaxle.
WARNING: HOLD ONTO DIFFERENTIAL ASSEMBLY TO PREVENT IT FROM ROLLING OUT OF HOUSING.
4. Remove differential assembly.
5. Set up dial indicator set C-3339 and tool C-4996 as shown in (Fig. 178) (Fig. 179) to measure side gear end play. Side gear end play must be within 0.001 - 0.013 inch.
6. Use Miller Special Tool 5048, 5048-3 Collets, and L-4539-2 Button to remove the differential bearing cone on the extension housing side.
7. Use Miller Special Tool 5048, 5048-4 Collets, and L-4539-2 Button to remove the differential bearing cone on the bearing retainer side (Fig. 180) (Fig. 181) (Fig. 182).
8. Using Miller Special Tool L-4518, remove the differential bearing race from the extension housing/ adapter plate.
9. Using Miller Special Tool 6062A, remove the differential bearing race from the bearing retainer (Fig. 183) (Fig. 184).
DIFFERENTIAL SERVICE TOOLS:
ASSEMBLY
NOTE: The differential is serviced as an assembly. The only parts that are serviceable within the differential are the differential bearing cups and cones. If any other part fails within the differential, you must replace the differential assembly along with the transfer shaft.
NOTE: Use Mopar ATF RTV (MS-GF41), or equivalent, on retainer and extension housing/adapter plate to seal to case.
1. Using Miller Special Tool L-4410, and C-4171, install differential bearing to differential (extension housing side) (Fig. 185).
2. Using Miller Special Tool 5052 and C-4171, install differential bearing to differential (bearing retainer side).
3. Using Miller Special Tool 6061 and C-4171, install differential bearing race to bearing retainer (Fig. 186).
4. Using Miller Special Tool L-4520 and C-4171, install differential bearing cup to extension housing.
5. Measure and adjust differential bearing preload.
6. Install differential assembly to case. Install extension housing/adapter plate and bearing retainer.
7. Install bearing retainer with a bead of Mopar ATF RTV (MS-GF41) and torque bolts (Fig. 187) to 28 Nm (250 in. lbs.).
8. Install extension housing/adapter plate with a bead of Mopar ATF RTV (MS-GF41) and torque bolts to 28 Nm (250 in. lbs.).
9. Install differential cover with a bead of Mopar ATF RTV (MS-GF41) (Fig. 188) and torque bolts (Fig. 189) to 28 Nm (250 in. lbs.).
