DISASSEMBLY

NOTE: The Quaife ATB Differential is serviced only as a complete assembly. The only serviceable components are the ring gear and tapered roller bearings. No other component replacement will be possible.

1. Remove differential side bearings:





a. Install Tool 8491-1 to differential case (Fig. 90).





b. Set up Tool 5048 (5048-1, -4, -6) as shown in (Fig. 91)





c. Remove differential side bearing (Fig. 92)





2. Remove ring gear-to-case bolts (Fig. 93).





3. Press ring gear off of differential case (Fig. 94).





4. Remove eleven (11) differential gear body halve bolts (Fig. 95). Separate halves, noting position and orientation of locating dowel.
5. Remove differential components and inspect (Fig. 96). Note assembly orientation of belleville spring washers.

INSPECTION
Wash all components in a suitable solvent and blow-dry with compressed air (except bearings). Inspect all components for excessive wear. Minor irregular wear and small gear chips are acceptable and do not inhibit differential operation. However, large gear chips or components discolored due to lack of lubrication should result in differential replacement.

ASSEMBLY

NOTE: The Quaife ATB Differential is serviced only as a complete assembly. The only serviceable components are the ring gear and tapered roller bearings. No other component replacement will be possible.








1. Assemble and install differential components as shown in (Fig. 96). Make sure center pack (spring housing and belleville spring washers) is assembled as shown in (Fig. 97).
2. Noting position of locating dowel, install flanged gear body halve.
3. Apply Mopar (R) Lock & Seal Adhesive to the eleven (11) gear body halve bolts. Install and torque to 39 Nm (28 ft. lbs.).





4. Install ring gear. Install and torque twelve (12) bolts to 95 Nm (70 ft. lbs.) (Fig. 98).





5. Using Tool 8473 and Tool 8491, install differential side bearings with arbor press (Fig. 99).

ADJUSTMENT - DIFFERENTIAL TURNING TORQUE

NOTE: Differential turning torque should only be measured with the geartrain out of the transaxle. If measurement is taken with transaxle assembled, an inaccurate measurement will result.

NOTE: All differential cover-to-case bolts and bearing plate-to-case bolts must be installed and torqued to obtain accurate measurement.

1. If transaxle is assembled, remove geartrain and leave differential in place.
2. Install differential cover and torque differential cover-to-case bolts to 54 Nm (40 ft. lbs.).
3. Install extension housing and torque extension housing-to-case bolts to 28 Nm (250 inch lbs.).
4. Place transaxle on work bench so axle centerline is parallel to the ground.
5. Install turning torque tool C-4995 to differential at side opposite extension housing.





6. Using inch lb./Nm dial indicator, rotate differential case multiple times and record measurement (Fig. 100). Differential turning torque should be within 2.3 - 3.4 Nm (20 - 30 inch lbs.). Refer to shim chart for proper shim selection. If turning torque measured is less than 2.3 Nm (20 inch lbs.), install a thicker shim. If turning torque measured is greater than 3.4 Nm (30 inch lbs.), install a thinner shim.
