Hey The awd clutches, c solnoid and awd valve body control are in the tail shaft housing. After romoving the exhaust, heat shields, drive shafts and cross member to tranny remove the tail shaft housing. take all parts to the bench. Take out the tail shaft with clutchs in it apply air pressure to hole in between the two seals on the shaft you should see the clutchs lock. then take a screwdriver and see if you can move them. If a. you dont see the clutchs move then the hole is clogged or b. ther clutches move after you apply pressure but they dont lock then the clutches are shot. If both are good then apply air pressure to hole in tail shaft housing case next to aluminum tube. should see air coming out of hole where the shaft was in the housing. if not remove tube blow air in tube if air comes out of tube, romove awd valve body and solnoid c. Remove filter/screen and see if theres a clog. also blow air in the same hole in case and make sure air comes through the hole where the valve block was. if air comes out of hole blow air in valve block and make sure vlave is not stuck. if it is then take valve block apart and clean valve reassemble and blow air through it again some times valve gets bent. if no air replace valve and the c solnoid. if the c solnoid goes bad it defaulfts to to full on awd all the time.
