Oscilating humming coming from left front wheel

I have a humming noise when driving my Jeep it is worse when decelerating and doesn't change when put in four-wheel drive. It sounds like it is coming from the front left wheel and makes an oscilating noise. What could this be?

Most likely its a wheel bearing , or hub bearing since the vehicle is 4wd.

My Dodge Grand Caravan is making a humming noise as you accelerate, while turning left it stops but gets worse while turning right. I replaced the left front wheel hub and no improvement, I need help


if hub bearing replacement did not fix the noise

when noises are on left and right turns
that has CV joints /drive shafts
would say they are the issue
replace both sides

and replace the left hand hub bearing at the same time

If it gets worse as you're turning right, but not left - Most definitely a wheel bearing on the right side. The right turn puts more stress on the right wheel - louder noise - turn left and release the stress - no noise. You can also lift the vehicle up on a jack and listen to the wheel and hear the bearing in the hub making noise.

Recently noticed when driving over 40mph, I hear a loud humming like tire tread noise, coming from the front. When I'm turning right it gets worse. Turn left and it virtually vanishes. Is this the...


yes.this means the left wheel bearing is bad, because when you turn right the pressure is pushing down on the left wheel causing noise and when you turn left the pressure then pushes down on the right side removing pressure from the left side causing noise to stop.. this is why when you turn one way or the other the noise stops and starts.

Whining/grinding noise at deceleration


We have the same problem at our shop. We haven't rebuilt the front differential yet. We tried 3 different shafts on 2 different Jeeps and the noise is on both just the same. By greasing the front driveshaft cv joint, we got he noise to quiet some, but it is still way to loud. With the driveshaft out, the noise is gone. We are about to buy a new shaft from the dealer for $600. There are some service bulletins about some noisy driveshafts.

Steering creeks when turning left or right. front wheel noise.


My advise is when u get a humming noise when banking left or right. Its beter to change both left and right wheel bearing and ball joints. Cause if u think about it those parts are put on at the same time . So if u think about it they have the same where in Terre . left or right hope this helps you.
