Don't Overlook Transfer Case Service
Any four-wheel-drive (4WD) truck or SUV and some cars with all-wheel-drive systems have a transfer case to provide power from the transmission to a pair of axles up front. The transfer case is a type of gearbox that enables 4WD operation. It often includes optional 4WD operation and standard rear-wheel drive when simply running errands around town or traveling down the freeway. That transfer case goes unseen and often gets overlooked for maintenance. That can lead to eventual failures if ignored.
