Pros:

1. OEM Equivalence: This seal is designed to be an OEM (Original Equipment Manufacturer) equivalent, which means it is engineered to match the specifications of the original seal that came with the vehicle.

2. Leak Prevention: A new pinion seal can help prevent leaks from the differential, which can lead to costly repairs if left unattended.

3. Improved Performance: A properly sealed differential can lead to improved performance by allowing the fluid to stay contained and lubricate the gears effectively.

4. Peace of Mind: Installing a new seal can give you peace of mind, knowing that your vehicle's differential is sealed correctly and will not leak.

Cons:

1. Cost: Replacing a differential pinion seal can be a costly repair, especially when considering labor and the cost of the seal itself.

2. Time-Consuming: This repair can be time-consuming, as it requires removing the differential cover, the old seal, and installing the new one.

3. Potential for Damage: During the seal replacement process, there is a risk of damaging other components, such as the differential gears or bearings, which can add to the cost of the repair.

Conclusion:

Ultimately, the decision to buy a national SX-FGW9 rear outer differential pinion seal for your 1983-1991 GMC S15 Jimmy JX depends on several factors, including your budget, the severity of the leak, and your personal priorities. If you value peace of mind and preventing costly repairs down the line, then replacing the seal may be a worthwhile investment. However, if you are on a tight budget or are not experiencing significant leakage, you may choose to prioritize other repairs.

Recommendation:

If you have a consistent leak from the differential and want to prevent further damage, it is recommended to replace the pinion seal. Ensure you purchase the correct seal from a reputable supplier, such as National, to ensure a proper fit and function. Additionally, consider completing the repair yourself to save on labor costs or hiring a trusted mechanic to ensure the job is done correctly.
