INSPECT AND REPLACE WHEEL BEARINGS
1. Remove front wheels.
2. The front wheels are equipped with sealed roller
bearings in both the front and rear of hub. Check the
bearings for damage by spinning the inner race by hand.
If the bearing binds or shows excessive wear, it must be
replaced.
3. Tap the bearings out from the back side with a long
drift and a hammer.
4. Install new bearings using a driver set.
