The transfer case on your four-wheel-drive (4WD) vehicle is located behind the transmission. Depending on how your system’s configured, it uses either a chain or set of gears to change your vehicle from two-wheel to four-wheel drive. This occurs through the driveshafts for the front and rear axles. The objective is to slow the rotational speed so that the wheels turn at the same time, creating greater force.

When you notice a situation, such as the 4WD lever popping out of gear, it could be the result of the transfer case losing oil. The seals can wear out with time and cause a leak. Gears grinding or not staying in place are symptoms of not having enough lubricant in the case.
