Toyota Wheel Bearing Pack

The wheel bearings collectively support the entire weight of the vehicle while simultaneously enabling the wheels to rotate freely and with minimum friction.

Packing the wheel bearings refers to replenishing the grease in the wheel bearings.

The grease tends to be displaced from the wheel bearings during normal use, so that often-especially with the smaller bearings used in cars-by the time we are repacking them with grease, they’re so empty of grease that we can see daylight through the wheel bearings.

Most vehicles come with sealed, non-serviceable wheel bearings now, but for the vehicles that came with serviceable bearings, the normal service interval is 30,000 miles.
