11 Hemi Overland Differential whine/ roar

Hello, I am a proud owner of my 2011 Jeep Overland Hemi with the quadra trac suspension and I am having issues. I took the Jeep to a track day and towed two motorcycles with a enclosed trailer and had no issues yesterday. Today I took the Jeep for a little light off road trail I know at low speeds with 4 low on and hill descend on everything was fine with no unusual noises until I made it back to dry pavement. Now I hear a roaring noise whenever the speeds are above 40 mph. Anyone have the slightest idea where I should look? I power washed the undercarriage then hand washed the truck to make sure all dirt and mud was off. I also have no warning lights on.

It appears to be coming from the left wheel. I am taking it off now to inspect

Mud caked up and removed but I'm still hearing and feeling the noise on the left side. Going down the road and making left bend turns I hear and feel the noise but doing the same thing on right bends, I don't feel or hear it. Any suggestions?

Wheel bearing is the typical suggestion with your left/right description.

I replaced the left front wheel bearing (where I was hearing the noise) and I STILL have the same noise! Around 30mph, it roars with a whomp whomp whomp not super loud, but definitely noticeable. Any other places I can look before I take it to a professional for an opinion?

How about a alignment,could be tire noise caused by a bad alignment.

Breaks ok? They can make that but more frequently squeal.

Sure it's out of 4x4?

It's a 2011 full time awd. I can rotate the tires but I seriously doubt that is it. More suggestions please... I'm already in the ****e house with my old lady!

Did you damage the tire? Roars are typically bearings, could be any one. Diff, transfer case. Most common is the wheel bearing you replaced, usually the easies least expensive bearing to get at. My Vette roared when a snap ring let go and got caught up in the overdrive bearing.

Roars could also be u-joint related, especially with the womp womp, but they typically are rumbles.

Some here have had issues with rear drive shafts, perhaps investigate that next.

Rear driveshaft issues

Never really experienced any roar or whomp whomp when my rear driveshaft failed it will start to slip and make other noises.

The noise is definitely front left and NOT in the rear drive shaft. It will be going to the dealer next week hopefully to be covered by powertrain warrenty.

Rotate tires

Goodyears could be the problem. Take the right rear tire and put it the left front and see if you get the same noise. Check any CV joint boots etc for holes.

No holes in boots and no damage to the tires. Rotated and the noise is still there
