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 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. Driveshaft balance issues can generally be felt at vehicle speeds over 30mi./h.

How much does it cost to have a driveshaft balanced? From what we researched via multiple quotes online, the average driveshaft balancing, including professional labor, tends to be in the $120 to $185. However, if you needed new U-joints, as well as the driveshaft balancing, which is often the case in most repairs, the price can be closer to $200 to $250+.

Can you rebalance a driveshaft? 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.

How do I check my driveshaft balance? – Related Questions

What does a bad driveshaft sound like?

Generally speaking, a bad drive shaft is going to create a kind of rattling or clunking sound. You may also hear sounds that are like a high-pitched squeaking or a scraping noise of metal on metal. All of this will originate from underneath your car, rather than in the engine compartment.

What causes drive shaft failure?

Improper stiffness matching between the left and right smooth shafts, which results in a larger torque transmitted to the right spline, is the root cause of the drive shaft failure.

How does a driveshaft become unbalanced?

Driveshaft: An unbalanced driveshaft causes a vibration that increases with vehicle speed. The driveshaft can become damaged or dented. Undercoating, mud, or a missing balance weight cause the driveshaft to spin out of balance. It results in a vibration that increases with vehicle speed.

Can a dented driveshaft be fixed?

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.

What does a driveshaft vibration 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.

What does a bad drive shaft look like?

Common signs include intense car vibrations and abnormal noises, like clunking, rattling, and scraping, coming from under the vehicle.

How long can you drive on a bad drive shaft?

If you allow the driveshaft to die completely, then it will reach the point where the wheels no longer receive any power. While there is no set lifespan of a driveshaft, it typically can last about 75,000 miles. Keep in mind depending on the vehicle, and wear and tear you may get much less or much more.

Is a broken drive shaft expensive to fix?

You can usually expect to pay between $320 and $750 for the average cost of the parts, while the cost of the labor is between $150 and $190. If you have a rear wheel or four wheel drive car, then the price of the broken drive shaft repair cost will be much higher.

Can you drive with a broken driveshaft?

Driving an automobile with a defective or damaged driveshaft is potentially dangerous. If there is any sign of trouble, the car should be taken in to a certified mechanic for immediate inspection for repair or replacement. Replacing or repairing a drive shaft can be very expensive.

Can a bad drive shaft affect transmission?

For vehicles equipped with driveshafts, they are an important part of the drivetrain and any issues with them can greatly affect the drivability of the vehicle. As they are underneath the vehicle and connected to the transmission, they may be difficult to access and service on one’s own.

Will 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 type of joint allows the driveshaft to lengthen or shorten?

The slip yoke and the u-joints allow movement between the suspension as it reacts to the road surface. When the rear suspension moves to compensate for the road, the driveshaft must become longer or shorter.

At what speed does a driveshaft vibrate?

First order driveshaft vibration is usually caused by a component rotating at the same speed as the driveshaft that’s out-of-round or out-of-balance. Driveshaft balance issues can generally be felt at vehicle speeds over 30 mph.

Why does my car shudder when I accelerate?

One reason your car could be shaking with acceleration is that the engine’s mounts are broken. If even one of the motor mounts is broken, this could occur, and puts more stress on the remaining mounts. Replacing broken motor mounts is one way to stop vibration during acceleration.

How long does it take to fix drive shaft?

That’s very difficult to answer due to the multiple variables involved in removing and replacing hard to access components such as the center driveshaft on a front wheel drive vehicle like your Edge. However, in general, this type of job can often be completed in one business day; or less than 8 service hours.

Is it hard to change a driveshaft?

That’s why your driveshafts are very important indeed. Changing your driveshafts is actually a simple task that a home mechanic can undertake without too much trepidation. It’s just a case of being thorough, being safe, and of course, having your trusty Haynes Manual to hand.

What angle should a driveshaft be?

Universal joint operating angles on each end of a driveshaft should always be equal within one degree of each other (one half degree for motor homes and shafts in front of transfer cases or auxiliary devices) For vibration-free performance, universal joint operating angles should not be larger than three degrees.

Can a driveshaft be offset?

There have been cars from the factories with offset engines and thus offset left-right driveshafts. As long as it doesn’t exceed the u-joints specs for angularity, it’s just fine.

What causes a universal joint to fail?

This usually happens because of corrosion, excessive jolting or vibration, or because the bolts were not properly torqued into place. A worn or cracking transmission or differential housing can also cause this. Of course, u-joint failure isn’t limited to these three causes.

Why are slip joints used in drivelines?

To cope with the difference in line with the level of the gear box output shaft and the differential input pinion shaft. So to adjust angular motion universal joints are provided and to adjust for the change in length of the propeller shaft , a slip joint is provided.
