Buy Oil Seal (Rear Output Shaft) (5013019AA)

The Mopar Output Shaft Seal 5013019AA (commonly referred to as the Oil Seal (Rear Output Shaft)

5013019AA) is a genuine OEM drivetrain component used to maintain proper fluid containment and

drivetrain integrity in many Jeep vehicles. Ith is specifically designed as a rear output shaft seal that fits

the back end of a transmission or transfer case where the output shaft exits the housing, helping to prevent

lubricants from leakingh out and contaminants from getting in.

Constructed by Mopar, this seal is manufactured to meet original equipment specifications, ensuring

compatibility and reliable performance across a wide range of models from roughly 2003 through 2025.

It functions by creating a tight barrier around the rotating output shaft, sealing the transmission or transfer

case housing to retain fluid and protect internal components such as bearings and gears. (Mopar America)

One of the key roles of the Rear Output Shaft Seal (5013019AA) is to prevent oil or transmission fluid

leakage. Without a properly functioning seal, fluid can escape around the output shaft, leading to low fluid

levels, increased wear, and potentially more serious drivetrain damage. In addition, a damaged or worn seal

can allow dirt, water, and other contaminants to enter the housing, which may accelerate internal wear or lead to component failure.

This oil seal is typically made from durable elastomeric

This oil seal is typically made from durable elastomeric rubber bonded to a metal reinforcement,

giving it flexibility and resilience against heat, pressure, and rotational friction encountered during normal

operation. The design ensures that it maintains flexibility and sealing effectiveness over long service

intervals. Although it’s a relatively small part, its performance is vital to the health of the transmission or transfer case. (MOPAR Giant)

Installation of the Rear Output Shaft Seal requires careful attention.

to the proper depth. Many technicians use a seal driver or socket that matches the outer diameter to ensure

it seats properly and doesn’t bind or distort during installation. Another important aspect is that this part is

backed by a manufacturer warranty (typically a minimum of 12 months), reflecting Mopar’s confidence in its quality and fitment. (Mopar America)

Overall, the Oil Seal (Rear Output Shaft) 5013019AA is a critical sealing component that ensures

reliable drivetrain operation by maintaining fluid integrity and protecting internal transmission or transfer

case components. Its genuine OEM construction and robust design make it a dependable part for maintaining vehicle performance and preventing costly fluid leaks
