• 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 (Rear) 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 vehicle using chain drives and gear reductions.

The transfer case output shaft on your vehicle joins the transfer case to the axle by the input shaft of the transmission and requires a Transfer Case Output Shaft Seal (Rear) to make sure that the parts maintain a tight connection. Without a functioning Transfer Case Output Shaft Seal (Rear), transmission fluid would leak from the rear and front output shaft.

If a worn out or damaged Transfer Case Output Shaft Seal (Rear) is causing the shaft to leak, the internal components of the transfer case may no longer be properly lubricated, which can damage the gears and chain drives by causing them to overheat or wear out. This internal damage can cause the whole transfer case to wear out rather quickly and become inoperable, potentially causing the vehicle's four-wheel drive to malfunction or stop working.

If your Transfer Case Output Shaft Seal (Rear) is old, damaged, or wearing out, you might notice a few symptoms. These indicators can include trouble with your INFINITI remaining in four-wheel drive, a metal-on-metal grinding noise underneath the vehicle, and issues shifting gears.

If you believe your Transfer Case Output Shaft Seal (Rear) is old or wearing out, replace it with a new part as soon as possible to keep the transfer case and other nearby parts from becoming damaged as well.

Replace your INFINITI's Transfer Case Output Shaft Seal (Rear) with a new replacement seal from INFINITI Parts. This Transfer Case Output Shaft Seal (Rear) 331407S110 fits your INFINITI QX56 2004-2010. Check the What This Fits tab for additional information.
