About a month ago i was playing in the mud and got some water in the vent i ran it about a week before i could get a chance to change the oil. Filled it back up and put the additive in it. Yesterday while i was backing up my drive in a straight line there was a poping sound like something is binding u joints are tight and yoke looks ok .could the clutches in the limited slip have been damaged and if so would it be better to just replace them with a sparten locker?
