INSPECT FRONT WHEEL
BEARINGS
1: Raise the front of the vehicle and support with
jack stands.
2: Grab the top and bottom of the tire/wheel
assembly. Feel for any movement or play while
pulling and pushing on the top and bottom of the
tire. Any movement or play is indication of loose
wheel bearings.
3: Spin the front wheel(s) by hand. The wheel
should stop spinning in no more than
2-revolutions. A wheel that continues to spin
freely is an indication of a loose wheel bearing.
Note: Refer to the Adjust Front Wheel Bearings
section for detailed information regarding the
proper adjustment of the wheel bearings.
4: Spin the wheel(s) and listen for any grinding
noise. Any noise may be an indication of worn or
damaged wheel bearings.
Note: Refer to the Replace Front Wheel Bearings
section for information regarding the
replacement of the wheel bearings.
5: Lower the vehicle.
6: Reconnect the battery.
7: Remove the blocks from behind the wheels.
8: Test drive the vehicle.

• The bearings must be lubricated before performing
this procedure.

support with jack stands.
2: While rotating the wheel
, tighten the front axle
nut until the wheel is difficult to rotate.
3: Continue to rotate the wheel for 5 compete
revolutions.
4: Attach a rope to the tire and wrap around the tire
with 1 foot remaining hanging in the air.
5: Tie a weight (see table and illustration below) to
the end of the rope.
6: Slowly loosen the axle nut until the hanging
weight rotates the wheel.
7: Remove the rope and weight.
8: Spin the wheel and listen for any grinding noise.
Any grinding noise may be an indication of worn
