Slack in right front passenger tire. and roughness going down the highway . Is this a wheel bearing out?

You have to jack the vehicle off the ground, then grab each tire at the 12:00 and 6:00 positions. Then as hard as you can try to wiggle the tire up and down. If there is any movement then that wheel bearing needs to be replaced.

The hum is probably a bad wheel bearing.

P304 is a cylinder misfire code.

Could be a bad wheel bearing. This is very dangerous, be sure and get it checked out asap. If the wheel comes off you're going to have a very bad day!

When you turn and hear a noise it is usually a CV Joint that is going bad. Humming can be a lot of things. Tires wheel bearings, rear end differential etc.

Sounds like front wheel bearings.
Does the sound go away when swaying one way or the other?
If you way left and ot gets louder it should be the right bearing and opposite for swaying right

Make sure your lugs are tightened down all the way. Also, be sure that even though they are tight, the wheel is put on straight. I would check your bearings as well, just to be sure it isn't something more serious.

Why drive side bearing could be a bad other.balance yes, tie rod could be bad.

To check how tight the front end is, place a jack under the lower arm of each front tire( make sur the car is secure and won't roll) and lift so tires are free of ground. Grasp the tires and try to turn them left and right. There should be minnimal movement. Check the steering components to see where the slack is, if any. If the seeering is tight have the tires checked for balance.

Almost any 60 series 15" tire will ride better than a 60 series 16" or lower. Rule of thumb: as the sidewall gets lower the ride gets worse, but handling is better. Living room couch or NASCAR....you decide
