Spicer U Joints are critical components in the driveline, and the 1350WJ Series is no exception. Designed specifically for the front wheel of 2007+ Jeep JK models, this U Joint replaces part number 5004891. With a cap diameter of 1.188″ and a width of 2.455″, it ensures a precise fit and reliable torque transfer between angled shafts.
This U Joint is non-greasable, which means it comes pre-lubricated for life. This design choice reduces maintenance needs while enhancing durability. However, keep in mind that this also means it cannot be rebuilt once it wears out. The inside snap ring style (ISR) helps secure the joint in place, preventing any unwanted movement that could lead to failure.
When installing this U Joint, pay attention to the following:
- Ensure full snap ring seating to avoid binding.
- Check for any signs of rust or dust around the caps, which can indicate wear.
- Do not hammer the caps during installation; this can damage the joint.
In Jeep JK applications, the Spicer 1350WJ U Joint handles the demands of off-road driving and aggressive shifts, making it a reliable choice for both daily drivers and performance builds. Trust Spicer for your driveline needs and experience the difference in quality and performance.
