1.10.1.2 Repair
Wind Noise/Air Sound
External Wind Noise
The wind noise leak repair is very similar to that of water
leaking. Refer to
. The actual repair procedures depend on the type
of seals.
Vibration
Tire and Wheel Balancing (On-Vehicle)
Carry out the balancing on the electronic wheel balancing
machine. Dynamic balancing machine is easy to use and can
be used both for static balance and dynamic balance. Unlike
the balancing on vehicle, the off vehicle balancing can not
correct the brake disc imbalance. However, the accuracy of the
off vehicle balancing can overcome this issue. Make a cone
through the center hole on the back, rather than through the
wheel nut holes.
Tire and Wheel Balancing (Off-Vehicle)
On-Vehicle tire and wheel balancing can correct the imbalance
caused by disc brake vibration.
Warning!
Support the control arm at the normal position to avoid
damage to drive axle. When the wheels travel to the
maximum low position, do not shift the gear lever.
1. Do not remove the balance weights during on vehicle tire
and wheel balancing.
2. If the balance weight is more than 25g (1lb), divide it into
two blocks and install one onto the inner wheel rim and the
other onto the outer wheel rim.
3. Engine driven gear and gear assembly.
Tires and Wheels Installation

thicker parts (also known as the high point) pointing to the
