NOISE OR VIBRATION IN TURNS
Vibration associated with the CV joints in the halfshafts occur in the 3rd and 8th order. Use a vibration analyzer to determine the frequency of the vibration.
| SYMPTOM | POSSIBLE CAUSE | REPAIR |
|---|
| Clicking noise while turning. | Lack of lube in CV joint boots. | Replace halfshaft |
| Chuckling or snap noise while turning. | Loose wheel or hub nut. | Tighten wheel or hub nut. Replace damaged components. |
| Loud knocking noise centering on inner CV tripod joints. | Damaged Differential side/pinion gears. | Remove halfshaft and rotate side gears by hand. Replaced damaged transaxle components. |
Noise may also be caused by another component of the vehicle coming in contact with the half shaft, brake or wheel assemblies.
CLUNKING NOISE DURING ACCELERATION
| SYMPTOM | POSSIBLE CAUSE | REPAIR |
|---|
| Clunk/snap noise during launch or shifting into drive or reverse. | Loose hub nut. Damaged hub splines. | Replace hub nut and properly tighten. Replace hub bearing and halfshaft. |
| Clunking noise at low speed. | Severely worn or damaged tripod or CV joint. | Replace halfshaft. |
| Rattle/clunk over bumps. Grease slung around undercarriage. | Loss of lube in CV joint boots. | Replace halfshaft. |
SHUDDER OR VIBRATION DURING ACCELERATION
| SYMPTOM | POSSIBLE CAUSE | REPAIR |
|---|
| Shudder or vibration on acceleration. | Engine rotating beyond limits. Worn or damaged half shaft inner tripod joint Severely worn or damaged suspension or steering component. Front end severely out of alignment. | Replaced damaged or worn engine/transaxle mounts. Replace halfshaft. Replace worn or damaged suspension or steering component. Align front end. Refer to WHEEL ALIGNMENT, STANDARD PROCEDURE . |
VIBRATION AT HIGHWAY SPEEDS
Vibration associated with the CV joints in the halfshafts occur in the 3rd and 8th order (3 or 8 events for each rotation). The inner tripod joint with three pivot axis has three events in each rotation of the halfshaft. This will produce a 3rd order vibration of the wheel rotation speed. The outer CV joint with 8 pivot axis balls has eight events in each rotation of the halfshaft. This will produce a 8th order vibration of the wheel rotation speed. An 8th order vibration will create a high pitch sound, like gear noise. Use a vibration analyzer to determine the frequency of the vibration before replacing components.
| SYMPTOM | POSSIBLE CAUSE | REPAIR |
|---|
| Low frequency vibration, matching wheel speed. Wheel balance and runout is OK. | Foreign material (plastic bags, organic sinew and road debris) fouling the halfshaft. | Clean debris from around halfshaft. |
| High frequency vibration matching 3rd order wheel speed. | Faulty inner tripod joint. Vehicle ride height is modified. | Replace halfshaft. Return vehicle to proper ride height. |
| High pitch whine sound with possible high frequency vibration in the floor matching 8th order wheel speed. | Faulty outer CV joint. Vehicle ride height is modified. | Replace halfshaft. Return vehicle to proper ride height. |
