Front end growls when in 4 wheel drive
Before using the 4wd, did you have the transfer case, front differential, and front axle locking hubs inspected, properly lubed, and tested? No one ever does, so don't feel bad if you don't know what shape the 4wd components are in. You probably haven't used 4wd in last five months. Most people don't ever put their 4wd vehicles in 4wd mode, even though the service manual says to operate the vehicle for a minimum of 10 low speed miles every 3000-4000 miles. This helps maintain the proper function of any limited slip parts, internal bearings, and gear components. Operating in 4wd periodically also helps insure any electric devices are working. What you may be hearing is the unused front differential parts, transfer case bits, or electrically controlled locking hubs wearing out from the lack of use, proper maintenance, or just plain age (after all you did say it's a 2001). Front pinion and differential bearings are not usually ever spun/rotated unless the transfer case and hubs are locked in 4wd. If they were starved of gear oil, or dry when you went 4wheeling, you torn them up. Refer to the owner's manual (if you still have it) for proper 4wd opration. You'd be surprised that there are proceedures to do in order to maintain a reliable vehicle. Don't ever just drop it in gear and expect it to work..... I mean come on.... after all, It is a Dodge! Your next step is to find a full service mechanic, with a complete selection of tools and shop supplies (especally a hydrolic press) and schedule an appointment to have the 4wd front components inspected and replaced if neccessary.
