I had new tires put on my 2004 Chevrolet Colorodo. Had the front end Alai said need a New hub and bearing so I them to put it on .. When they got through the ABS light was on they have worked to get it to go off and have not been successful. Had new brake shoe put on thought that might help , but the ABS light is still. It was not that way when they worked on my truck and I don't intend for it to happen that way.

The front wheel bearing for your Impala is an integrated wheel hub/bearing/ABS.
The whole thing gets replaced. It should look like the one off my Bonneville; Bearing.

Remove wheel/tire. Remove brakes. Remove rotor. Remove axle nut. Press-out axle shaft*. Unplug ABS connector. Remove 3 bearing bolts.
*To press out axle, you may need a special tool from an auto parts store.
Don't forget to put the heat sheild back on during reassembly, and the axle nut need to be very tight.



After Bearing/hub removed:

it is your wheel bearing. the bearing is a sealed unit so you replace the hub assembly. remove wheel,caliper,brake rotor.if it is 4x4 loosen axle nut. there are three 15mm bolts on back side of spindle remove these and slide hub out replace with new one. most hubs come with new wheel speed sensor so remove harness from connectors or if no new one remove the screw holding it in place to hub and slide out.

Front hub bearing, remove tire, remove caliper and caliper holding bracket, you do not have to remove brake caliper from brake hose, just set it aside, if 4X4 remove front axle nut that goes through center of rotor, also remove brake rotor, disconnect elec, A.B.S connector, remove three bolts on back side of hub bearing, remove hub bearing, some times you will need to knock hub bearing out with a hammer.Reverse to install new hub bearing.

Have front tire's check out, but more then likely you have a bad front hub bearing. Have it taken to a repair shop where they can put it up on a lift and checked.

remove tire remove axel nut (large nut in center of hub)remove brake rotor and caliper turn hub until you can see 3 bolts through round hole in hub turn hob until you remove all 3 bolts. Bolts are in triangel pattern. remove hub and bearing. good luck

I think your right that its a bad bearing or hub. If your feeling it in the gas pedal and the floor, its most likely the front. If you can find an empty parking lot, try to get up to the speed it starts making the noise, and turn left and right. With the extra load being put on each bearing from turning, that will tell you which side it is.

yes front wheen drives have hub bearings. Most of them need the hubs to be pressed apart to replace them. the hub bearing supports the end of the CV drive shaft closest to the wheel. hope that helps.

your hub bearing needs to be replaced.i bet it sounds like a airplane.

1. Remove the tire and wheel center cap.
2. Remove the drive axle nut.
3. Raise and support the vehicle. Remove the tire and wheel. .
4. Remove the brake rotor.
5. Disengage the wheel drive shaft from the wheel hub and bearing. Place a brass drift against the outer end of the wheel drive shaft in order to protect the wheel drive shaft threads. Sharply strike the brass drift with the hammer. Do not attempt to remove the wheel drive shaft from the wheel hub and bearing at this time.
6. Remove the wheel hub and bearing from the steering knuckle by removing the three bolts coming in from the back side of the knuckle.

Of course you may have to use a hammer to loosen the bearing from the knuckle.

Good Luck
