Checking Input Shaft Bearing Turning Torque
8. Verify that a preload condition does not exist. Use Special Tool L-4508 and an inch-pound torque wrench to check input shaft turning torque. The
turning torque should be less than 5 in. lbs.
CAUTION: Step (1) MUST be repeated every time a thinner shim is installed. This will assure that the input shaft bearing cup is pressed the
proper distance into the case. It the turning torque is too high, install a 0.O4mm (0.0016 inch) thinner shim.
9. Recheck input shaft turning torque. Repeat step (8) until the proper bearing turning torque is obtained. Observe CAUTION in step (8).
DIFFERENTIAL BEARING PRELOAD ADJUSTMENT
1. Remove bearing cup and existing shim from differential bearing retainer. (See Differential Bearing Retainer in Subassembly Recondition section).
2. Select a gauging shim which will give 0.025 to 0.254mm (0.001 to 0.010 inch) end play.
SUGGESTION: Measure original shim from differential bearing retainer and select a shim 0.381mm (0.015 inch)thinner than original for the
gauging shim. Install gauging shim in differential bearing retainer and press in bearing cup. Installation of oil baffle is not necessary when
checking differential assembly end play.
3. Oil differential bearings with SAE 5W-30 engine oil and install differential assembly in transaxle case. Check extension housing O-ring for
damage (replace if necessary). Add a 1/16 inch bead of MOPAR Gasket Maker, Loctite 518, or equivalent to extension flange. Install extension
housing and differential bearing retainer. Torque bolts (see Tightening Reference).
4. Position transaxle with bell housing facing down on workbench with C-clamps. Position dial indicator.
5. Apply a medium load to differential with Tool C-4995 and a T-Handle, in the downward direction. Roll differential assembly back and forth a
number of times. This will settle the bearings. Zero dial indicator. To obtain end play readings, apply a medium load in the upward direction while
rolling differential assembly back and forth. Record end play.
Checking Differential Bearing End Play To Determine Shim Thickness
6. The shim required for proper bearing preload is total of gauging shim thickness, plus end play, plus (constant) preload of 0.254mm (0.010 in.).
