	Transfer Case Mounted behind and driven by the vehicle transmission, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep vehicles and offers high and low range.

Front wheel bearings are in a sealed hub assembly, when they go bad you'll be able to rock the tire when holding it at 12 and 6. They are held onto the axleshaft with a 36mm axle nut, and to the knuckle by three 13mm bolts from behind the knuckle.

The transfer case works in 2wd, but just the mainshaft to the rear ouput. The front output us disengaged.[addsig]
