Hub Assembly Replacement Cost: How to Save Money

A hub assembly bolts to the knuckle on one side, holds the wheel bearings, and has the wheel bolted onto its other side. In the past, there would have been multiple replaceable and serviceable parts involved: bearings and races, the hub flange or integrated rotor, grease seals, and the spindle. It was also necessary to remove and re-grease the bearings from time to time and to carefully set the bearing preload on reassembly.

The advantage of a hub assembly is that it’s all one piece and sealed, so no servicing is necessary. Of course, the disadvantage is that if anything goes wrong, the whole thing needs to be replaced. But they are generally very reliable and long-lived parts, and they are also pretty straightforward to replace. Usually, the brakes need to be removed out of the way, and then the hub assembly can be unbolted from the knuckle.

On vehicles with ABS, the tone ring and speed sensor are included as a part of the hub assembly. Usually a new hub comes with a new speed sensor installed and tested, so you also need to undo the old sensor wire from it’s clips and disconnect it, then route and connect the new one in. It is possible to reuse an old speed sensor, but the exact gap between the sensor and the tone ring is critical, and if it is even a tiny bit off, it can cause problems with the signal and disable the ABS.

Costs of Hub Assembly Replacement

On average, the cost of replacing a hub assembly is about $400 for a passenger car and about $500 for a light truck. That includes labor, which is about an hour in most cases.

For some more specific examples of the costs of replacing a hub assembly on some common vehicles, using $150 an hour as a labor rate, see:

On a 2009 Ford Fusion with a 3.0-liter engine, the labor time to replace the rear hub assembly is .9 of an hour. A rear hub assembly costs about $110 for a Timken part or about $180 for an OE part. This would make the job of replacing the rear wheel bearing about $245 with aftermarket parts or about $315 with OE parts. The front of the vehicle uses a press-in cartridge bearing rather than a hub assembly.

For a 2012 Chevrolet 1500 with four-wheel drive, the labor time for the front hub assembly replacement is 1 hour. The factory replacement part costs about $443, or a Raybestoes hub assembly costs about $315. This makes the job about $593 using OE parts or about $465 using aftermarket parts. On the rear of the vehicle, axle bearings pressed into the differential housing are used.

On a 2004 Camry with a 3.0 liter engine, the labor time to replace a rear hub assembly is 1.6 hours. A factory part lists for $660, or an SKF part costs about $180. That makes the job about $900 using OE parts or about $420 using aftermarket parts. On the front of the vehicle, a press-in cartridge bearing is used.

How to Tell if a Hub Assembly Needs Replacement

Almost always, it is the bearings that wear out, so the normal symptoms of a failing bearing are what’s looked for, which would be a grinding noise when the vehicle is moving. Each hub assembly has an inner and an outer bearing, usually, one or the other will go first, and after steering a little one way, the other loads or unloads each bearing in turn. Most of the time, a suspected bearing noise can be checked that way on a test drive; steering one way, then the other, the noise should get worse, then better, as the bearing is loaded and unloaded.

Even then, it can be tricky to tell which side the noise is coming from, as sounds transmit pretty freely through a vehicle. Usually, the car is put up on a hoist and run in gear while someone listens at each hub with a stethoscope to confirm the noise. Other signs are sometimes rust particles shedding from a bearing seal, showing a dry bearing breaking down. Or, if the bearing is pretty far gone, looseness and play at the wheel.

If a bearing is worn to the point that the hub is actually loose, then that will also cause the wheel to go out of alignment, which can be noticed as a change in steering wheel position, tire wear, and possibly a pull to one side or the other. It can also cause the ABS tone ring to fall out of alignment with the sensor, which can trigger an ABS warning light to turn on.

A hub assembly that has a bearing problem should be replaced as soon as possible and driven as little as possible until it is replaced. Too much play can prevent the brakes from functioning normally and, if left long enough, even allow the wheel assembly to break free. A wheel bearing that is just a little noisy can generate enough heat at highway speeds to experience what we call “sudden catastrophic failure”, which is best avoided.


  • Do I need an alignment after replacing a hub assembly?

No. For some years, when hub assemblies were becoming common, it was recommended to check the alignment after replacing one, but there was hardly ever any need. Current manufacturing tolerances are more than precise enough that it’s unnecessary.

  • How long should a hub assembly last?

There is no normal expected life span, and there is no maintenance that can be done. Usually, if a hub assembly lasts over 100,000 miles (and they usually do), that’s considered decent.

  • Can I re-use the old speed sensor?

Yes, but it’s not a good idea; the air gap in the tone ring is critical and can vary enough between any two manufacturers to cause a problem. That’s why new hubs come with new speed sensors installed, if applicable.

  • How hard is it to replace a hub assembly?

Generally, it’s pretty straightforward, not much more difficult or involved than servicing the brakes. Rust can seize things into place, but lacking that, it’s about a one-hour job in most cases, assuming the right tools are at hand.
