# Wheel Bearing Replacement in Upland > Wheel bearing replacement in Upland: bolt-on hub units or press-in bearings, installed and torqued to spec, then road-tested so the hum is gone.

Route 66 Auto Repair in Upland replaces worn wheel bearings on cars, SUVs, trucks and vans once testing confirms which corner is failing. This page explains the replacement job itself: the kind of bearing your vehicle uses, what we replace alongside it, and how we confirm the hum is gone. ASE-certified technicians give you a written estimate first, and they torque the axle nut to the manufacturer's specification, because a bearing is only as good as how it was installed. ## What kind of wheel bearing does your vehicle use? Most newer cars and SUVs use a hub unit: the bearing, hub and often the wheel speed sensor come as one sealed assembly that bolts to the knuckle. It is usually the quicker job, and the sensor is new at the same time. Other vehicles use a bearing pressed into the steering knuckle. The knuckle comes off, the old bearing is pressed out, and a new one is pressed in with a new retaining clip. It takes more labor, but the part often costs less. Older trucks and trailers may use tapered bearings that are packed with grease and adjusted by hand. Your written estimate shows every step for your vehicle. ## What do we confirm before replacing a bearing? A bearing hum can move around the car, and one noisy corner can sound like another. We confirm the corner with a road test and a check on the lift before ordering parts, and we rule out tire noise first. If you want the full testing story, our [wheel bearing noise repair](https://route66autorepairshop.com/drivetrain-and-additional-mechanical-services/wheel-bearing-repair) page covers diagnosis. We also check the brake pads and rotor on that corner, since the brakes come off anyway. ## Our wheel bearing replacement process 1. **Confirm the corner:** Road test and lift check, with a photo or a short explanation of the play we found. 2. **Disassemble:** We remove the wheel, brake caliper, rotor and axle nut, and disconnect the ABS sensor where needed. 3. **Replace the bearing:** We bolt in the new hub unit or press in the new bearing, depending on the design. 4. **Reassemble to spec:** Axle nut, caliper bolts and lug nuts are torqued to the manufacturer's values. 5. **Road test:** We drive the car again to confirm the noise is gone and that no ABS light appears. ## What's included in wheel bearing replacement - Road test before and after - New hub unit or pressed bearing with a new clip - New axle nut where the manufacturer requires one - Axle nut and lug nuts torqued to specification - Brake pad and rotor check on the same corner ## Is wheel bearing replacement need-now or need-later? **Need now:** - Play you can feel when rocking the wheel - A grinding or roaring sound that is getting louder - An ABS or traction light that came on along with the noise **Need later:** - A faint hum on one corner with no play ## How wheel bearing replacement is priced The main price driver is the design: a bolt-on hub unit versus a press-in bearing, and front versus rear. Rusted axle nuts and seized hubs on older vehicles add labor. We quote after confirming the corner, the estimate is in writing, and we stop and ask if the job grows. AAA members get 10% off parts and labor, up to $75. Most bearing jobs fit in a day when parts are on hand and the board allows. ## After a wheel bearing replacement The hum should be gone right away. If you still hear something, it may be the other side or [tires with uneven wear](https://route66autorepairshop.com/tire-services/tire-wear-analysis), so call us and we will road-test it again. If an ABS light stays on after a few drives, bring it in. Hard hits on potholes or curbs shorten bearing life, so worn [suspension parts](https://route66autorepairshop.com/suspension-and-steering-services) are worth checking too. ## Frequently asked questions ### Should I replace wheel bearings in pairs? Not always. Bearings do not wear as evenly as brake pads. We replace the one that has play or noise and tell you how the other side looks. If it is close to failing, it goes on the estimate as a need-later line. ### Why does my ABS light come on with a bad wheel bearing? On many cars the wheel speed sensor reads a magnetic ring built into the bearing. When the bearing wears and wobbles, the signal gets erratic and the ABS system sets a fault. Replacing the hub unit usually clears it. ### Do I need an alignment after a wheel bearing replacement? Usually not for a bolt-on hub. Some press-in jobs disturb parts that affect alignment. If yours needs one, we tell you up front. Alignment is not done in-house, so we arrange it and road-test the car afterward. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
