Driveline Repair for Heavy Trucks

The driveline carries every bit of engine torque to the drive axles. Worn parts cause vibration, noise and eventually failure. Emergency Roadside Truck & Trailer Repair inspects and repairs drivelines on semis and work trucks in Phoenix.

Driveline Services

  • U-joint replacement.
  • Carrier (center support) bearing replacement.
  • Slip yokes and splines.
  • Driveshaft inspection and replacement.
  • Inter-axle driveshaft and power divider issues.
  • Driveline vibration diagnosis.

Signs of Driveline Problems

  • Vibration at certain speeds.
  • Clunk when taking off or shifting.
  • Squeaking or grinding under the truck.
  • Grease slung around U-joints.

Lubricating U-joints and slip yokes at each PM service is the easiest way to prevent driveline failures.

Driveline Angles and Vibration

Driveline angles change when ride height, suspension or axle position changes. If vibration started after suspension work, the angles may be off. We check ride height and angles as part of vibration diagnosis, not just the U-joints.

Frequently Asked Questions

What causes driveline vibration?+

Worn U-joints, a failing carrier bearing, incorrect driveline angles, a bent or unbalanced driveshaft, or loose yokes.

How often should U-joints be greased?+

At every PM or according to the manufacturer’s interval; dry U-joints fail early.

Can a bad U-joint be dangerous?+

Yes. A failed U-joint can drop the driveshaft and damage the truck or cause a loss of control.

Can a carrier bearing be replaced on-site?+

Often yes, depending on the truck and location.

Why does my truck vibrate only at highway speed?+

Balance, driveline angles or a worn carrier bearing are common causes.
