How do I know if my drive shaft is bad?

Signs of a bad driveshaft/drivetrain

1. Vibrations from under the vehicle. A common symptom of a failing driveshaft is an intense shaking coming from underneath the vehicle.
2. Difficulty turning.
3. Loud clunking noise.
4. Car shudders upon acceleration.
5. Squeaking noise.
6. Clicking or knocking noise.

Is chain or shaft drive better?

Besides giving you the smoothest driving experience, a shaft-driven motorcycle also has a longer lifespan than that of a chain-driven motorcycle. They offer much less noise and go longer periods without maintenance as compared to chains.

How do I check my driveshaft balance?

To field balance a driveshaft, raise vehicle parallel to the ground so that the vehicle can be started and the tires and wheels can rotate freely. Measure about six inches from the yoke end, and place four marks 90 degrees apart around the driveshaft. Number them so that they can be identified.

What does an unbalanced drive shaft feel like?

A common symptom of a failing driveshaft is an intense shaking coming from underneath the vehicle. Worn out u-joints or bushings can cause the driveshaft to vibrate. Vibrations caused by tire balance issues are speed sensitive while driveshaft vibrations aren’t.

Can you rebalance a driveshaft?

Driving over rocks or heavy debris often causes drive shaft problems. Dented drive shafts cannot be rebalanced, they need to be replaced. Fortunately, you can fix minor imbalances by balancing the drive shaft, a procedure that requires minimal parts — only hose clamps.

What happens if driveshaft is out of balance?

A First order driveshaft vibration will cause one shake or disturbance for each revolution of the driveshaft. IMPORTANT: Anything that is out of balance will only cause a first order vibration, never any higher order vibrations. A component rotating the same speed as the driveshaft that is out-of-round.

Can you fix a dented driveshaft?

To fix a damaged drive shaft that has been twisted or bent. The drive shaft tubing must be replaced and the other components must be checked for damage also. If your drive shaft has a dent in the tubing, most of the time you can straighten and balance the shaft to compensate for the dent in the tubing.

Can a dented aluminum driveshaft be fixed?

If that dent were in an alloy shaft, it would have shredded. Steel is more durable, and can be repaired by any driveshaft shop.

Can a dented driveshaft cause vibration?

A bent or damaged driveshaft can result in vehicle vibration. Driveshaft’s on rear-wheel vehilces the driveshaft will rotate two and a half to four times the speed of the wheels. Due to the relatively large size of the rear-wheel drive shafts and high speed, vibration is significantly increased.

What causes a bent drive shaft?

Inertial excitation vibrations Inertial vibrations are also caused by the operating angle at the drive end of your drive shaft. Inertial vibrations also create bending on drive shaft attaching components.

How much does a driveshaft play cost?

With the car’s weight on the tires, you should be able to take the rear u-joint loose and push the driveshaft forward about 3/4 of an inch until the yoke bottoms out. Any less than that and you risk bottoming the yoke on bumps.

How do you measure to shorten a driveshaft?

Make sure the rear suspension is loaded (like it would be sitting on the ground). Slide the trans yoke all the way in until it stops, then pull it out ½ – ¾ inch. Then measure from the u-joint center on the yoke to the u-joint center on the rear end.

How do I know what size U joint?

The width of the joint is measured across the ends of the caps as shown for outside locks. Inner lock type joints should be measured from the outer side of the lock groove.
