Universal Joints 5320-3422039 for KAMAZ

The universal joint with the part number 5320-3422039 is a component used in the driveline systems of certain vehicles, notably those manufactured by KAMAZ, a Russian truck producer. This universal joint facilitates the transmission of rotary motion between shafts that are not in a straight line, accommodating angular misalignments in the vehicle’s drivetrain.

Applications of U-joints 5320-3422039

Automotive Driveline Systems

Used in KAMAZ trucks, buses, and heavy-duty vehicles to transfer rotary motion between shafts at an angle.

Ensures smooth torque transmission despite misalignment in the drivetrain.

Agricultural Equipment

Used in tractors and other farm machinery, allowing flexible movement in power transmission systems.

Helps connect drive shafts in PTO (Power Take-Off) applications.

Industrial Machinery

Applied in conveyor systems and manufacturing equipment where shafts need to transfer motion at an angle.

Common in rotating machinery that requires flexibility in shaft connections.

Wear Symptoms

Vibrations

  • Low-speed vibrations: Could indicate U-joint wear in the propeller shaft (driveshaft).

  • High-speed vibrations (50+ km/h): Often means the U-joint is badly worn or unbalanced.

  • Steering wheel shaking? Could also point to driveshaft imbalance from a failing joint.

Clunking or Knocking Noises

  • When shifting gears (D/R): A “clunk” means excessive play in the U-joint.

  • When accelerating/decelerating: Indicates loose or damaged bearings inside the joint.

  • Constant rattling? The U-joint may be completely worn out and needs urgent replacement.

Grease Leakage

  • KAMAZ U-joints are greaseable (have a nipple for lubrication).

  • If grease is leaking, the seals are damaged, allowing dirt inside to accelerate wear.

  • No grease left? Metal-on-metal contact  heat buildup & failure risk.
