I just changed the front wheel bearing on my 1996

Hit in the rear axle may have damaged bearings or brake parts. Jack up the side you hear noise from, put on stand, then have helper rotate wheel while you look underneath and listen to see where noise is coming from. Use length of old fuel or heater hose, one end in ear, to locate exactly where noise comes from.

it's your front wheel bearing

While driving and with radio off, listen to the noise. Find a road that is clear on which you can drive without any traffic. Drive at a constant speed and make light shifts to the left and right, by doing this, the weight of the vehicle will shift to the apposite side of the steering wheel to which you turn.
When you turn to the left, the weight goes to the right (passenger side) wheel, if the noise stops, you may have a bad wheel bearing.
When you turn to the right, the weight goes to the left (driver side), if the noise stops, you may have a bad wheel bearing.
If the noise does NOT go away, then you may have bad CV's.
Another way to check is by lifting and securing in jack stands. Vehicle in neutral and with your hands, rotate wheel with one hand. Other hand place on suspension component. Spring of strut. If you feel slight vibration, you may have a bad wheel bearing.
With vehicle on jack stands, one hand on top of wheel and other on bottom, try to see if you can move the wheel in and out which may be a had CV.

Is the sound constant with the speed of the vehicle or speed of the engine? Does applying the brakes or turning change the noise? Does the grinding sound like metal to metal contact?

First remove the wheel that has the grinding noise and rotate the wheel to hear the noise. If it is a muffled grinding noise it will be the bearing. If external it will be a fully worn brake pad

You should definitely pull the front wheel and check the bearings (they are roller bearings, not ball bearings). With the wheel off, you should be able to isolate where the noise is coming from, but I vote for the bearings. Check, replace and/or repack, and adjust properly. If you have noise, you should be able to feel the "play" in the bearings, or see the wear problem on the spindle and bearings. I hope this helps you.

It's not a easy job you will need a press to take the old one out and replace the new one, my advice to you is take the steering knockle out and have your local shop press the bearing out for you and put the new one in. This way you just have to bolt everything back up and your good to go.

are your front right brake pads worn more than your front left? if so probable cause is the rotor. if not, most likely wheel bearing

Did you replace one front bearing or both? It could be the other front wheel bearing.

IF THE NOISE IS IN THE FRONT AND ONLY WHEN WHEELS ARE TURNING AND THE GRINDING NOISE CHANGES WHEN TURNING LFT. OR RGHT. COULD BE FRONT WHEEL BEARING..OR CV JOINT..
