Land Rover Defender: Wheel and Tire Assembly Balancing
GENERAL PROCEDURES
CHECK
CAUTION:
Only Jaguar Land Rover approved wheel and tire balancing equipment must be used
during this
procedure.
NOTES:
1. Remove the wheel and tire(s).
2.
- Adjust the tire pressure(s) to 36psi / 2.5bar / 250kPa.
- 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.
3.
- 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.
4.
- 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).
7. Lower the vehicle.
8.
- Tighten the wheel nuts to the specified torque.
- 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.
