  Note

Do "not" use an impact wrench to install the wheel bolts.

  • Before mounting a wheel, carefully clean all rim contact surfaces for the wheel hub, the wheel hub and the surfaces for the wheel bolts on the rim.
  • Before installing the wheel bolts, carefully clean the thread and the cap contact surfaces.
  • Apply the Optimol Paste -G-052-109-A2-to the threads on the wheel bolts. Refer to Parts Catalog.
  • Do "not" use an impact wrench to install the wheel bolts.
  • Install all wheel bolts, until the wheel is securely fitted to the wheel hub. Only then can the vehicle be placed on the ground.
  • Tighten all wheel bolts to the tightening specification for when the vehicle is stationary on the ground. Refer to → Chapter "Wheel Bolt Tightening Specifications"
  • Retorque each individual wheel bolt to the required tightening specification at least one time. Refer to → Chapter "Wheel Bolt Tightening Specifications"

If all of the assembly steps were performed carefully and correctly, the wheel bolts do not need to be re-tightened after the vehicle has been driven a specific distance.
