Just bought this vehicle and there is a whine from the front end. Didn't hear it on the test drive. The whine goes away when I let off the gas. It sounds like ring and pinion. Is this normal awd sounds? I have never owned an awd vehicle and do not know what to expect. Thanks

these vehicles must not be used in ANY 4WD operation on dry solid pavement...the noise is common when the front axle is locked together in any 4WD position...IF the noise is in 2WD then it appears that the front wheel bearings are bad,,,normally this will cause the abs to activate and stopping will be a problem, as the abs with start pulsing, causing a longer stoping distance.
the front wheel bearings are a common failure item...
whenever you have a 4WD/ALL wheel drive vehicle you must keep the tires rotated and the tire wear needs to be equal on all tires,,if not the drivetrain gets damaged...
