I just changed the driver side hub bearing and the lights on the dashboard went off but before i didnt hear the humming noise at first but after i changed it..now im hearing the humming but the lights on the dashboard not on wht should i do..??

It'* possible the new hub is just a bit louder. But check over everything to make sure nothing is rubbing.

Im thinking of just changing the other side even tho its only 6 months old. I don't know what to do about it tho cause no lights are on. I could get the wheels in the air and spin them tho right..??

Also have the brake rotors checked. Bad hubs can take the rotors with them.

bearings have to be just about ready to fall off before you hear them with no weight. try moving the tires to the back see if the noise follows

did you torque the shaft nut to the correct ft/p?
