Hey guys - new to this forum and am at a loss for things to check at this point. I recently lifted my 2000 cherokee and rebuilt the transfer case (np231) with SYE and a new double cardon drive shaft and when accelerating, mostly when everything is cold, i get a whooshing/clickong noise coming from the rear half of the vehicle and am having a hard time determining where the noise is coming from and dont want to pull the tcase again if my problem is diff related. Im posting s video soon. Up on jack stands i can spin the rear shaft and wheels and hear no noises. Any advice would be great. Stay tuned for a link to the video on youtube.
