The front left wheel makes a howling sound at + 50 mph. When I turn the wheel right sharply, noise stops. Tires are new. This is a half ton Dodge Ram truck.Any suggestions?

with the wheel bearings failure , it is very possible that the "U" joint or cv joints for the front drive were damaged
I would be looking in that area especially as you mention on turning right

Try getting on an open road, get up to about 45 MPH or where ever the noise is loudest. Put the car in neutral and turn the engine off. You can roll in a straight line for a long time. Make sure nodody is around you. If the sound stops when the engine is off, then the noise is coming from the motor. If the sound is still there, its got to be coming from the tires. Id guess a wheel bearing.

This might be a wheel bearing problem. All of your symptoms point to this except for the noise going away when the tires were changed. If you jack your car up and spin the tires by hand sometimes you can find one that is louder and sounds rougher than the rest. This indicates a faulty wheel bearing.

The first thing I would check is for a bad wheel bearing. If the noise lessens when turning left than I would look at the left front first. Chalk the rear wheels or set the emergency brake. Put the transmission in neutral. Jack up the left side of the car. Grab the coil spring and rotate the tire by hand. If you can feel/hear the noise than your on the right track with the bad wheel bearing. I can give you instructions on how to replace if you need them.

Check wheel bearings, most likely front 1 or both. get up to speed and take some corners, if it quits down when turning right, the front right wheel bearing is bad. If you turn left and it quiets down, then its the left front thats bad(important to maintain 30-50 mph). They are sold as the whole hub. Also check your front tires, run your hand across the inside and outside edge and see if they are worn uneven, this can make a lot of noise if the tires are bad. if thats the case, have someone check the ball joints and tie rods, if they are bad, it will do that to the tires, thus the unevenly worn tires making a paddling noise effect.

check that, and you may have a bad wheel bearing on that side.

sounds like it could be wheel bearings but I'm surprised that when they rotate the tires they didn't catch this.

The next time you have your tires rotated ask to have the jacked up front end tested for loose front end parts. They can shake it down physically looking for play in the ball joints, tie rod ends, and bearings.

Struts generally wear out and cause a bouncy front end conditioin. Brakes, if properly assembled, won't make any additional noise when turning left or right.

Good luck on this.

You probably have a bad hub bearing.If you can change the noise by slightly turning the vehicle one way or the other it is a hub bearing.If you turn left and the noise is still there then it is the right front bearing.If you turn right and the noise is still there it is the left side.If it makes the noise both ways it could be both front hubs.Hope this helps.Good luck.

well did the noise start after the tires were rotated?could be choppy tires,,,if not ,i strongly think it sounds like a bad wheel bearing,,,,if you drive and while its making the noise turn left and right quick and see if the noise gets louder and which way turning makes it louder,,if you turn leftand it gets louder its usually the right wheels bearing as you are putting load on it, if it makes the noise louder while turning right its the left wheel bearing,,,got it

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
