| Driveline clunk - loud clunk when shifting from REVERSE to DRIVE |
Damaged or worn Constant Velocity (CV) joints |
INSPECT the Constant Velocity (CV) joints for wear or damage. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Damaged driveshaft center bearing support |
INSPECT the insulator for wear or damage. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Driveline clunk -- occurs as the vehicle starts to move forward following a stop |
Worn driveshaft CV joint with excessive play |
INSPECT the CV joint for a worn condition. INSTALL a new driveshaft if necessary. REFER to: Rear Driveshaft . |
| Damaged driveshaft center bearing support |
INSPECT the insulator for wear or damage. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Buzz - buzzing noise is the same at cruise or coast/deceleration |
Incorrect driveline angles |
CHECK for correct driveline angles. REPAIR as necessary. |
| Rumble or Boom - noise occurs at coast/ deceleration, usually driveshaft speed-related and noticeable over a wide range of speeds |
Driveshaft out of balance |
CHECK the driveshaft for damage, missing weights or undercoating. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Grunting -- normally associated with a shudder experienced during acceleration from a complete stop |
Driveshaft CV joint binding |
INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Driveline shudder - occurs during acceleration from a slow speed or stop |
Driveline angles out of specification |
CHECK for correct driveline angles. |
| Binding or damaged driveshaft CV joint |
INSPECT the driveshaft CV joints and coupling shaft for wear or damage. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Driveline vibration - occurs at cruising speeds |
Worn or damaged driveshaft center bearing support |
CHECK the insulator for damage or wear. ROTATE the driveshaft and CHECK for rough operation. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Loose axle pinion flange bolts |
INSPECT the axle pinion flange. TIGHTEN the pinion flange bolts to specification. REFER to: Rear Driveshaft . |
| Excessive axle pinion flange runout |
CARRY OUT a runout check. REPAIR as necessary. |
| Driveshaft is out of balance |
CHECK the driveshaft for damage, missing balance weights or undercoating. CHECK the driveshaft balance. CARRY OUT a driveline vibration test. |
| Binding or damaged driveshaft CV joint |
INSPECT the driveshaft CV joint for wear or damage. INSTALL a new driveshaft as necessary. REFER to: Rear Driveshaft . |
| Excessive driveshaft runout |
CARRY OUT a runout check. |
| Driveline angles out of specification |
CHECK for correct driveline angles. REPAIR as necessary. |
