The All Wheel Drive (AWD) models of the Tempo/Topaz utilize a rear driveshaft to deliver power from the transaxle to the transfer case which is mounted at the rear of the vehicle and used to drive the rear halfshafts. Serviceable U-joints are located at either end of the rear driveshaft.
REMOVAL & INSTALLATION
- Raise and support the rear of the vehicle safely using jackstands.
- Matchmark the driveshaft U-joints to the companion flanges at either end.
- Loosen the nuts and bolts holding the retaining straps to the companion flanges.
- Remove the retaining straps from one of the companion flanges, then support the driveshaft to prevent damage to the joint on the opposite end.
- Remove the retaining straps from the other end of the driveshaft, then remove the shaft from the vehicle.
- Align the matchmarks made earlier, then install the driveshaft to one of the companion flanges. Loosely install the retaining straps using the fasteners.
- Align the matchmarks on the other end of the shaft and loosely install the retaining straps.
- Verify proper positioning, then tighten the fasteners securing the retaining straps to the companion flanges.
- Remove the jackstands and carefully lower the vehicle.
Before starting this procedure, purchase a new set of U-joint bearings.
- Remove the driveshaft from the vehicle.
- Place the driveshaft in a vise with the U-joint needing work closet to the vise.
- Using a pair of snapring pliers, remove the 2 snaprings from the U-joint
Wear protective eyewear to shield your eyes in the event a snapring comes loose during the removal or installation.
- Use U-joint removal and installation tool T74P-4635-C or equivalent to press out the bearings connecting the U-joint to the driveshaft. Once the bearings are pressed out, the assembly can be separated from the driveshaft, then the bearings can be removed and discarded.
- Remove the remaining bearing from the U-joint assembly and discard.
- With the bearing removed, clean the remaining assembly and allow to dry.
- Install the U-joint assembly to the driveshaft with 2 new bearings at either end.
- Use the U-joint removal and installation tool T74P-4635-C or equivalent to press the bearing into place.
- Install a snapring at either end of the U-joint assembly to secure the bearing in place.
- Position the remaining bearings on the U-joint assembly, and hold in position.
- While holding the bearings in place to prevent them from falling off, remove the driveshaft from the vise and install on the vehicle.
With the components of the driveshaft removed, inspect each for signs of damage or excessive wear. If the driveshaft is heavily dented, bent or shows signs of extremely damage, purchase another unit. Although this is a rare occurrence, because the driveshaft is open to the elements on the road, damage is possible.
