Wheel And Tire Assembly Balancing (G2436053): Check

CAUTION: Only Jaguar Land Rover approved wheel and tire balancing equipment must be used during this procedure.
NOTE:
  • If a retailer sub-contracts tire replacement and/or balancing the contractor must be suitably equipped with the JLR approved wheel and tire balancing equipment. 
  • Until flat-spots are removed, significant vibration/shimmy may be present. A road test is required to make sure temporary tire flat-spots are removed. For longer term flat-spots, a longer road test may be required. The road test should be completed on normal open roads (highway is optimal) to allow the highest speed that speed limits and road/traffic conditions safely allow.
  • All road tests must be performed with tire pressures at 29psi/2.0bar/200kPa.
  1. Remove the wheel and tire(s).

    Refer to: WHEEL AND TIRE

    • Adjust the tire pressure(s) to recommended (cold) settings.
    • Using the JLR approved tire balance equipment, balance the wheel and tire assembly until the residual imbalance dynamic is minimized.
    • Target is 0g (zero grams) on each plane; maximum is inner 5g, outer 5g.
    • Use the 'bulls-eye' balancing mode to minimize residual imbalance.
    • NOTE: For all markets except NAS.

      The maximum Radial Force Variation (RFV) values should be as follows:

    • 60N (6.1kg, 13.5lbf) First Harmonic.
    • 100N (10.2kg, 22.5lbf) Peak to Peak.
    • NOTE: For NAS market only.

      The maximum Radial Force Variation (RFV) values should be as follows:

    • 70N (7.1kg, 15.7lbf) First Harmonic.
    • 110N (11.2kg, 24.7lbf) Peak to Peak.
    • If these levels cannot be achieved, perform the following:
    • Remove the tire.
    • Follow the match mounting procedure as detailed by the wheel balance equipment.
    • Mark the high point of the 1st harmonic RFV on the outer (and inner for future reference) sidewall of the tire.
    • On vehicles installed with electric power steering: Install the lowest 1st harmonic RFV wheel/tire assemblies to the rear axle. On vehicles installed with hydraulic power steering: Install the lowest 1st harmonic RFV wheel/tire assemblies to the front axle.
    • Print out the results of the balance and force variation (before and after), and attach to the repair order.

    Prior to tightening the wheel nuts, the high-point of RFV should be marked and the road wheel and tire assembly installed to the vehicle with the RFV high point at the top.

  6. NOTE: Nothing should be used to brace the wheel while tightening the nuts as this can disturb the match mounting.

    Install the wheel and tire(s).

    Refer to: WHEEL AND TIRE

  7. Lower the vehicle.
    • Tighten the wheel nuts to the specified torque.

      Refer to: SPECIFICATIONS

    • Adjust tire pressures to recommended (cold) settings.
  9. Road test the vehicle for approximately 8 Km (5 miles), if possible road test the vehicle at speeds up to approximately 80 Km/h (50 mph).
  10. Return the vehicle to the customer with a full explanation of the situation/flat-spot scenario, and how it can/does affect driving the vehicle until the wheel and tire reaches normal operating temperature.
