HOWLING NOIS ONLY ONE RIHGT TURN COMING FROM LEFT

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

Have you checked you tire closely.Change it with the one on the other side and see if the sound transfer to that side.

Possibly bad wheel bearing/hub assembly. There is one for each front wheel. Usually if it quiets down turning left, then the front left would be bad and vice versa.

Here are a couple of things to check for. When driving turn car left and the right to see if noise gets louder then quieter. If so you will need a bearing hub. Also check power steering fluid in pump, if low you will get a howling noise. Looking for a noise is difficult task from a computer. Hope this gives you a starting point.

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

WELL WHAT YERA IS THIS TRUCK AND IS THE SOUND COMING FROM FRONT OR IS COMING DOWN DRIVE LINE IT COULD BE AT TRANSFER CASE THAT WHY IT GOSE AWAY WHEN IN FOUR WHEEL YOU COULD PULL THE DRIVE LINE IN FRONT AND SEE IF NOIS GOSE AWAY THEN ITS IN FRONT IF ITS THERE WITH DRIVE LINE OUT PUT IN GEAR AND IF NOIS GOSE AWAY THEN ITS THE TRANSFER CASE

It is probably your right axle bearings. How fast are you going when you turn? When you turn left, the weight transfers to the right side and loads the axles. If you are on the smooth straight stretch of highway and gently turn left and right, but stay in your lane, does it do it? If so, it's bearings.

These Cherokees are prone to rear end problems. I have one!

I think its a problem with your timing belt. It is too tight. Thats why it is making such a sound. Tell your mechanic to loosen it a bit.
