If you're the kind of person who looks forward to getting greasy after discovering a leak, then a transfer case shift shaft seal is a fun part to replace yourself. You don't even have to be part of the gear squad. When looking at drivetrain parts in a Jeep differential, the transfer case is the part that keeps fluids from leaking into the transmission from the input shaft. A leaking drive train is a huge risk to Jeep differentials because drive train parts can fail from overheating if the seal is damaged. A damaged transfer case often has problems with shifting between two- and four-wheel drive, which puts a serious crimp in any off-roading plans.
When to Check on the Transfer Case Shift Shaft Seal
Unlike motor oil, the transfer case does not have a fluid indicator inside the cab. However any leaks, particularly those that are reddish in color, should be investigated right away to ensure that the seal is still intact. If you find yourself having difficulty shifting gears even when not on a white-knuckle hill or you hear a lot of noise coming from the rig's gears, then it's time to get under the hood and replace the transfer case shift shaft seal before the engine fails. Any engine with four-wheel drive needs the transfer case to function or the engine won't work at all.
