Cause
This condition may occur when the VT25E transaxle belt has malfunctioned.
Correction
1. Disassemble and clean debris from the transaxle.
2. Inspect the front differential transfer gear, drive pinion gear and the front differential carrier ring gear for excessive wear or damage.
3. Inspect the bearing assemblies on the front differential transfer gear for damage or wear. If a bearing assembly needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.
4. Inspect the drive pinion bearing cup on the transmission case assembly for damage or wear. If the bearing cup needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.
5. Inspect the drive pinion gear bearing cup on the torque converter and differential housing assembly for damage or wear. If the bearing cup needs replacement, refer to Front Differential Transfer Gear Bearing and Cup Replacement in SI.
6. Place the front differential carrier and the front differential transfer gear into the housing.
7. Rotate the differential housing several times in both directions to check for knocking, gear bind or movement caused by small areas of damage (nicks/chips) on the gears. If the gears do not rotate smoothly, replace the differential carrier and the transfer gear. Refer to Front Differential Carrier Removal and Front Differential Transfer Gear Removal in SI.
8. Re-assemble the transaxle with a new case cover assembly. Refer to Case Cover Assembly Installation in SI.
