Hello, I have problem on my 2004 Kia Rio, with right rear wheel bearing, it stuck and has noise. what you can suggest to do?

Jack it up and try moving the wheel in and out at the top and bottom, and again left to right. If there's movement, you should be able to isolate it to a ball joint, A-arm bushing, or a wheel bearing (though the entire front suspension should have been checked while changing out the rack).

You have a check light on
What codes have you gotten you can share with us?
What problems has the vehicle been having & why
were they not addressed & properly repaired?

Collapsed rear wheel bearing or worn brake shoes or pads. You will need to pull the wheel and hug off to check both.

Not normally, they are replaced on an as as when basis.

Checked during service, if found to be loose/failing, then replaced.
Also replaced if known to be warn, usually signified by a rumbling noise from the area
of the offending wheel.

wheel bearing gone

front wheel bearing is bad check by swirving left and right if it is louder while turning right the left bearing is bad and if its louder going left the right is bad or both could be going

pull off rim. there is a cap in the center of the hub that you will have to tap/pry out with a screwdriver, then remove bolt and slide hub off.
thats how i fixed mine.

The rear drums are held on by a spindle nut. You first must remove the dust cap then unstake the nut and remove it. Behind that is a retaining washer and the outer bearing. The bearings can become a little stuck in which case a hammer can usually persuade them to loosen up.

Go to autozone.com enter your car info in. go the repaor section and it will be there.

lift the vehichle to check for wheel bearing play apply pressure to the top and bottom of the tire in a rocking motion. any movement indicates bad wheel bearings or ball joints. watch for where the movement is
