WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the bearing cup from the differential bearing retainer using Remover 6062A.
- Remove existing shim from under bearing cup.
- Reinstall the bearing cup into the retainer using Installer 6061 and Handle C-4171.NOTE: Oil baffle is not required when making the shim calculation.
- Install the bearing retainer into the case. Tighten bolts to 28 N.m (250 in. lbs.).
- Position the transaxle assembly vertically on the support stand and install Differential Tool L-4436-A into the bearing retainer.
- Rotate the differential at least one full revolution to ensure the tapered roller bearings are fully seated.
- Attach a dial indicator to the case and zero the dial. Place the tip on the end of Differential Tool L-4436-A.
- Place a large screwdriver to each side of the ring gear and lift. Check the dial indicator for the amount of end play.CAUTION: Do not damage the transaxle case and/or differential retainer sealing surface.
- Using the end play measurement that was determined, add 0.18 mm (0.007 inch). This should give you between 5 and 18 inch pounds of bearing preload. Refer to the DIFFERENTIAL BEARING SHIM CHART to determine which shim to use.
- Remove the differential bearing retainer. Remove the bearing cup.
- Install the oil baffle. Install the proper shim combination under the bearing cup.
- Install the differential bearing retainer. Seal the retainer to the housing with Mopar® Silicone Rubber Adhesive Sealant. Tighten bolts to 28 N.m (250 in. lbs.).
- Using Differential Tool L-4436-A and an inch-pound torque wrench, check the turning torque of the differential. The turning torque should be between 5-18 inch-pounds.
NOTE:
If turning torque is too high, install a 0.05 mm (0.002 inch) thicker shim. If the turning torque is too low, install a 0.0 5mm (0.002 inch) thinner shim. Repeat until 5-18 inch-pounds of turning torque is obtained.
