How long does a bearing take to replace?
Rear wheel drive, tapered roller bearing: about 15-45 minutes; wear gloves or spend another 10 minutes washing grease off your hands. Front wheel drive with pressed on bearing: 30–120 minutes depending on whether it can be pulled off and pressed in with a specialty tool.
Do you have to replace the front wheel bearings?
Don’t just replace, for example, bad left front wheel bearings without also replacing the right front ones, regardless of their condition. You also should replace the spring-loaded seals that keep the wheel bearing grease from escaping out the backs of the hubs and dirt and water from intruding into the grease cavity.
How long does it take to service tapered wheel bearings?
How we test gear. Conventional tapered wheel bearings need regular service, which is simple and takes just an hour or so.

The first step when checking for worn wheel bearings is to get the tire off the ground. Chock the wheel on the opposite corner fore and aft. Set a safety stand under the corner you’re working on after you jack it up. Grasp the whole wheel assembly at the top and bottom (12 o’clock and 6 o’clock positions)…
How are wheel bearings used in a car?
Wheel bearings, a part of a vehicle’s wheels, do the job of spinning the wheel freely and with minimal friction. The wheel center has a hub that houses a metal axle shaft. This shaft accommodates the bearings, which are actually a metal ring holding steel balls.

If you notice a humming or whirring noise while you are driving or your ABS light turns on, it may be time to change your bearings. You can save money by changing your own wheel bearings rather than going to a mechanic, but if you do so, use caution — the bearings may be small, but they’re very important.
Can a car’s wheel bearings be serviced if they are in great condition?
They also support the weight of an automobile that could weigh close to 2 tons or more. When the wheel bearings are in great condition there are no problems. Most wheel bearings are factory sealed and cannot be serviced, but replaced instead.
Where to put wheel chocks when changing wheel bearings?
For example, you would place wheel chocks behind the rear tires if you are fixing a front wheel bearing and behind the front tires if you are working on a rear wheel. Loosen the lug nuts and lift the wheel using a jack. For proper access to the internal components of the wheel whose bearings you’re replacing, you’ll need to elevate the wheel.
When to clean and repack tapered wheel bearings?
Good maintenance dictates that the bearings should be cleaned and repacked any time the brake disc is removed from the spindle. Conventional wheel bearings come in two pieces: the tapered cage assembly of rollers with the inner race, and the tapered outer race that presses into the brake disc (or drum) hub.
