Each time we drive our jeep we are getting a loud whining sound


This could be caused from a number of things.

Brakes shes or rotors
Worn tires uneven read wear
Bad wheel bearings.

You can rule out the brakes by 50% chance of it being this if when your driving it and you stil hear this noise without applying pressure to the break pedal. Although a pad that came off may be stuck on the rotor causing this.

Tires or more like a huming and vibrating.

Bearings are common and sound like a whirling and more pronounced as the speed picks up in the vehicle.

At 40 to 50 mph I hear a whine coming from the rear of the truck, I have put two quarts in the rear end thinking it was low but it getting worse.


Noises are tricky. It could be a lot of things. If your are sure that the noise is in the rear end, consider U-joint harmonization as a possibility. They could be worn. You could be hearing bearing wear and there is no "band-aid for that, you just have to get in there, determine which bearing it is and fix it. You might be hearing noise from the gears themselves. Again, once a gear wear pattern is set, it's there until you replace the gears. Listen to hear if you are only hearing the whine under acceleration or under deceleration (no brake) that will help determine if you are hearing a gear wear pattern that is on the drive or the coast side of the gears. Sorry there's no quick fix additive that I know of but hopefully this helps guide you to the root cause.

HAVE 2004 JEEP GRAND CHEROKEE,HAS LOW WHINING NOISE FROM LEFT FRONT. CHECKED BRAKES AND ROTORS AND ALL IS OKAY. DRIVES NORMAL AND DOES NOT SEEM TO BE BEARINGS. sTARTS AT ABOUT 20 MPH AND STOPS AT 50 MPH.OR...


the whinning noise is definalty a signiture of the bearing, and they do on occasion start making the noise long before other systoms of a bad bearing appear. There is really nothing else in the suspension that moves in a manner to cause the whinning pitched sound, other than the axel, but there signature has allways been a clicking around turns, so id definatly look cloesr at the bearings......good luck
