I have a 2015 XRS DPS and on a ride in Tenn this weekend coming out of a steep mud hole I had my left front tire off the ground and when my visco was trying to engage it was making a god awful ratcheting sound and was not locking correctly. Upon further inspection back at base I found fluid running out of the rear of the diff around the driveshaft yoke. We had been running in the rocks at Tackett most of the day and I had no problems and no such sounds, I am assuming the diff is smoked and I am wondering what the best option for replacement is. Any help will be greatly greatly appreciated!!
