2009 Liberty 4 Wheel Noise

[Woodman]

I have a 2009 Liberty, this just started yesterday. When we switch to 4 wheel the noise coming from below the shifter is bad. Almost sounds like metal on metal, when switch back to 2 wheel it goes away, not fully but close. Does the noise also in reverse. Any help would be appreciated. Has 104,000 miles and the 4 wheel system has never been or needed service.

At 104,000 is " has needed " service but someone just has not done it
Start by checking the CVs in front driveshaft

Had the same issue, few months back, turned out to be the rear CV joint of the front drive shaft . Made a very tin-y pinging noise when in 4x4 and nothing in 2 wheel drive.
