On-the-Car Wheel Balancing
ON-THE-CAR WHEEL BALANCINGCAUTION:
1. When doing on-the-car wheel balancing on a full-time 4WD vehicle, to prevent the wheels from rotating at different speeds on indifferent directions from each other (which could lead to damage to the center differential or transaxle gears), always be sure to observe the following precautions:
a) All four wheels should be jacked up, clearing the ground completely.
b) The wheels be driven with both the engine and the wheel balancer.
c) The mode select lever on the transaxle of the viscous coupling type center differential should be in the viscous (normal) mode position.
d) The parking brake lever should be fully released.
e) None of the brakes should be allowed to drag.
2. Avoid sudden acceleration, deceleration and braking.
3. Carry out the wheel balancing with the transmission in 3rd or 4th gear.
1. JACK UP VEHICLE SO THAT ALL FOUR WHEELS CLEAR GROUND AND CAN BE ROTATED
The wheels will be rotating fast, so make sure the vehicle is firmly supported on stands.
2. RELEASE PARKING BRAKE FULLY
3. MAKE SURE THAT BRAKES ARE NOT DRAGGING ON ANY OF FOUR WHEELS
4. PLACE WHEEL TO BE BALANCED ON WHEEL BALANCER
Follow the procedure specified by the wheel balancer manufacturer.
5. START ENGINE
6. PUT TRANSMISSION IN 3RD OR 4TH GEAR
7. ENGAGE CLUTCH SLOWLY, THEN GRADUALLY INCREASE SPEED TO TEST SPEED
8. ROTATE WHEELS USING BOTH ENGINE'S DRIVING FORCE AND DRIVING FORCE OF WHEEL BALANCER AND CHECK WHEEL BALANCE
NOTE:
- When doing this be careful of the other wheels, which will rotate at the same time.
