What does a bad drive shaft sound like?
Another symptom of driveshaft issues is loud clunking noises. These noises are usually produced by worn-out u-joints. The ability of your driveshaft to rotate correctly is altered if your vehicle has a faulty u-joint. Lack of u-joint lubrication can cause squeaking noises when you drive at low speeds.
How do you inspect the drive shaft of your vehicle?
Inspect the center bearing bracket, bracket bolts and mounting hardware and ensure they are not loose or broken. Inspect the center bearing bracket for cracks. With hand pressure only, push up and pull down on the driveshaft to check for movement in the center bearing carrier.
What happens when a driveshaft is out of phase?
If the driveline is left out of phase even the small unfelt oscillations and unbalances will wear on the driveline components and eventually lead to failure. U-joints, transmission output seals, and differential seals will all be placed under the stress of the driveshaft moving up and down.
How do you tell if you have a bad U-joint?
Signs of a Bad U-Joint
- Clunking or Clanging. Your vehicle’s U-joint may eventually wear at connecting points to the drive-shaft.
- Vibrations. If your driveshaft is out of balance, it’s often because of a defective universal joint.
- Grinding or Chirping.
- Loud Banging.
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 do bad u-joints feel like?
A bad u-joint can cause a clunking sound or jerkiness while driving, particularly when letting off of and pressing the accelerator. A bad u-joint can also cause vibration at certain speeds, emanating from the center or rear of the vehicle. If a u-joint is excessively worn, there’s an easy test you can perform.
Can a driveshaft be balanced?
For a driveshaft to be properly balanced, the torque coming from the engine and transmission must be equal to the speed at which the shaft spins. Balancing your driveshaft will ensure smooth driveline operation and help prevent the dangerous and destructive effects of an out-of-balance driveshaft.
What causes driveshaft vibration?
Vibration in a driveshaft can be caused by many conditions. One of the most common cause of driveline vibration are worn U-joints or slip splines, out-of-balance components, yokes out of phase or misaligned angles, approaching critical speed range, and yoke ears that are not concentric with the splines.
How do you know when to replace u-joints?
When you notice any of the symptoms listed below, check your u-joints as soon as possible.
- Clunking/clanking noise when you shift gears.
- Vibration when accelerating or decelerating.
- Loud metal-on-metal banging (this is a sign that the u-joint will completely fail very soon)

What are the symptoms of a bad or failing Guibo?
Driveline vibration is the #1 symptom of failure. And typically if you let your Guibo (flex disk, whatever you call it) get that bad, you also will have a bad driveshaft carrier bearing too. The one off my automatic E46 went 193k miles and was still ok but not great.
