Signs of a troubled drivetrain

  • "Clicking" Noises When Turning
  • A Knocking or Clunking sound
  • Grease on the edge of the Tires
  • Vibration While Driving

The Drivetrain consists of the driveshaft, CV (Constant Velocity) joints, the differential, the axle shafts, and the U-joints.

Driveshaft balancing

The driveshaft transfers torque to the other drivetrain components, it is normally designed to withstand shear and torsion stresses. To prevent failure it must be properly balanced, as an out of balanced shaft can be detrimental to the vehicle's performance.

Vibration is the most common indication of the driveshaft or other components being out of balance.

As soon as you vibration coming from your vehicle’s driveshaft do not hesitate to contact us, our technicians will diagnose the type of vibrations occurring and make all necessary repairs.


The Differential transmits engine torque to the wheels, it often splits this torque in order for the wheels to spin different speeds in order for added handling and maneuverability. As time goes by, the oil used in differential loses its ability to lubricate the gears and can overheat the gears.

Differential service is normally recommended after 15,000 to 30,000 miles ( Remember to always check your owners manual)

All Pro Automotive Technicians are specially trained to deal with various types of differentials, You can trust our techs to fully service your differential in order to get you on the road in a timely manner.

NOTE: Putting too much stress on a new car before allowing it to "break-in" or excessive towing can cause your differential to overheat and start to break down


The U joint or universal joint is a flexible pivot point that transmits power allowing for varying angles of the driveshaft. As time goes by, the oil will need to be serviced.


A Constant Velocity (CV) Axle, is a half shaft with a constant-velocity (CV) joint that helps transfer power from a vehicle’s transaxle or differential to the wheels. When the CV joint begins to fail, your car will start to pull as one wheel loses power. When the joint breaks completely its opposite wheel will no longer turn, and although the engine may still run, the car won't move.

CV joint failure is usually due to the wear and tear of the CV Boots which causes the system to develop a leak. Its common practice not to rebuild CV joints as it is more cost-effective to have them replaced.
To schedule, a CV joint or full axle replacement contact All Pro Automotive.
