Road Test, Performing Before Balancing
If a vehicle comes to the workshop with the complaint vibration, a road test must be performed before balancing the wheels.
- That way, information about the type of vibration can be obtained.
- Observe at which speed range the disturbance takes place.
-- Raise the vehicle on the platform immediately after the road test.
-- Mark the installation position on the tire.
-- Remove wheels from vehicle.
CAUTION:
If brake pads are ceramics, wheel must not fall on brake disc, otherwise it will be irreparably damaged. To remove/install wheel, install long assembly pin instead of wheel bolts in top position (12:00 position) and short assembly pin in wheel bolt mounts for support. In this way, the wheel can glide on the assembly aids when removing/installing.
-- Balance the wheels.
