Wheels: Testing and Inspection

Wheel Balancing

ADJUSTMENT

NOTE: Because an adhesive type weight is adopted for the outside balance weight of 17-inch and 18-inch wheels, change the setting of the wheel balancer to adhesive type weight.

1) Remove the balance weights.

CAUTION:
^ Be careful not to damage the wheel.
^ Completely remove the double-sided tape of the adhesive weight from the wheel.

2) Using the wheel balancer, measure wheel balance.
3) Select a weight close to the value measured by wheel balancer.

CAUTION: Use SUBARU genuine balance weights.











4) Install the selected weight to the point designated by the wheel balancer.

CAUTION:
^ Degrease the wheel surface where the adhesive type weight will be applied.
^ Press the adhesive type weight by 25 N (2.5 kgf, 5.6 lb) or more per 5 g (0.18 oz) for 2 seconds or more and attain full adhesion.
^ Total application of the adhesive type weight should be 100 g (3.53 oz) or less.
^ The total weight of all adhesive weight on models with transmitters (tire pressure sensor) is to be 120 g (4.23 oz) or less.

5) Using the wheel balancer, measure the wheel balance again. Check that wheel balance is correctly adjusted.

NOTE: Knock-on type balance weights for aluminum wheels can be used on any 15 to 18 inch aluminum wheels.
