• Seals the connection between the transfer case and the transmissions input shaft
• Can wear out over time and cause fluid leaks
• Replace if you have difficulty shifting, there's a grinding noise under the vehicle, or there are issues with four-wheel drive

The Transfer Case Output Shaft Seal is found on the transfer case of four-wheel-drive INFINITI models. The transfer case is responsible for transferring power to the rear wheels on a four-wheel-drive INFINITI by utilizing chain drives and gear reductions.

The transfer case output shaft connects the transfer case to the axle with the transmission's input shaft and requires a Transfer Case Output Shaft Seal to ensure that the connection is secure. Without the Transfer Case Output Shaft Seal, the rear and front output shaft would leak transmission fluid.

If a broken or worn out Transfer Case Output Shaft Seal is causing a leak, the low fluid level can no longer properly lubricate the internal parts of the transfer case, potentially causing the chain drives and gears to wear out, overheat, or break. This can quickly cause the transfer case to become damaged and even inoperable, potentially causing the vehicle's four-wheel drive to malfunction or stop working.

If your Transfer Case Output Shaft Seal is old, damaged, or wearing out, a few symptoms may be present. Some of these symptoms may include a metal-on-metal grinding sound from underneath the vehicle, trouble shifting gears, and trouble with your INFINITI staying in four-wheel drive.

If you believe your Transfer Case Output Shaft Seal is old or wearing out, replace it with a new part as soon as possible to avoid damaging the transfer case or other nearby components.
