Wheel Bearing Replacement
How are wheel bearings replaced?
To replace a wheel bearing, a technician will need put the car on a lift, remove the wheel and tire, and remove the brake caliper and rotor.
On some vehicles, the wheel hub and bearing are simply unbolted from the steering knuckle and can replaced as a unit. On other vehicles, though, the hub and bearing are pressed together into the knuckle and need to be removed with special tools. In these cases, a hydraulic press must be used to insert the new hub.
Can I replace the wheel bearing myself?
Some vehicles with sealed front wheel bearings can be serviced at home. If the wheel hub and bearing are simply bolted to the knuckle and can be replaced as a unit, an intermediate DIYer with experience removing brake or suspension parts can do it.
But many cars require that a technician remove hubs and bearings that are pressed into the knuckle. These components are difficult to disassemble, and reassembly requires a hydraulic press. In such cases, wheel bearing replacement is best left to a professional technician.
