How to Tell if Your Transfer Case Has Gone Bad
A bad transfer case is a wild card, and the symptoms of a failing case can vary significantly. Some jeepers claim that it becomes difficult to shift gears, while others report a high-pitched squeal or other unusual noises. However, one common symptom is the random shifting of gears mid drive. If you're on the road and go from 2 high to 4 low without shifting gears yourself, chances are your transfer case is turning bad and that it's time for a replacement.
