I have a 04 Jeep liberty with 102,000 miles on it and owned it since October 11th. I've never had any problems with my Jeep until tonight when I engaged my 4 high when getting stuck in snow. When I put my Jeep into 2 high, it started making a loud whining noise from under the Hood, began smoking and vibrating and began driving rough. The Jeep was picking up speed like normal but the noises and vibrating would become worse when you push on the gas. Can someone help me out!?

SOURCE: Makes a low roaring noise when you are at crusing speed.

One of the front wheel bearings are bad. Jack it up and see if one is loose, the noise will usually change if you swerve back and forth while driving. Could also be a rear pinion bearing in the rear axle.

SOURCE: whining noise under the hood only when I let up on

Pull the dipstick while it is making the noise, if it goes away it is pcv box, or nipple fitting under the intake
