4x4 Jaring Noise

From : Annonymous

Q: i have a 2000 dodge dakota that makes a jolting clunking sound in 4wd. this happens in both low and high ranges. it only happens under a load and has occured driving on the snow covered highway and on a dirt fire road. the last time on the fire road it took about 1/2 a mile to start and then repeated the jolt every 20 seconds or so. you can feel the jolt and the sound sometimes comes from the rear of the truck sometimes the front and sometimes in the transfer case area. the local dealer has checked the front and rear differentials and the transfer case. all fluids have been changed. there were no metal shavings anywhere. .
