What it does

Clunks when shifting into gear, vibration at speed or clicking in turns point to worn driveline parts. Drivetrain parts carry power from the engine to the wheels; noise, vibration, slipping or leaks are the usual signs a part is due.

Installation & tips

  • Mark driveshaft orientation before removal and torque fasteners to spec.
  • Gear oil: Refill differentials with the right gear oil.
  • Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
