FAQ
What is the CE-9112NRK-BDL-4P?It is a four-joint internal service bundle for narrow-width 2-inch Johnny Joint bodies, with one bushing, two retaining washers, and one snap ring for each joint.
Which Johnny Joint bodies accept these kits?Use them only in narrow-width 2-inch Johnny Joint outer bodies measuring 1.20 inches wide, whether the bodies are forged or weld-in.
Will these parts fit standard-width 2-inch joints?No. Standard-width joints use different internals, so verify the 1.20-inch narrow body width before ordering.
How many joints can this bundle service?The supplied quantity services four compatible Johnny Joints when each outer body and pivot ball remain suitable for reuse.
What is the bushing outside diameter?RockJock specifies a 2.188-inch outside diameter for each one-piece urethane bushing.
How thick are the retaining washers?Each of the eight side retaining washers is 0.112 inch thick.
Which grease should be used?Use non-synthetic high-moly grease that meets RockJock's service guidance.
Can a powered grease gun be used?No. RockJock requires a hand-pump grease gun because excess pressure from over-greasing can damage the joint.
Which service tool applies?RockJock identifies its CE-9112T Johnny Joint tool for assembly and disassembly of these components.
Installation Instructions
- Confirm that all four existing joints have 2-inch outer bodies and the 1.20-inch narrow width; do not install these internals in standard-width joints.
- Verify the package label and manufacturer part number CE-9112NRK-BDL-4P before disassembling any joint.
- Support the suspension safely, remove each joint according to the vehicle or fabrication service procedure, and keep components organized by joint.
- Use the applicable RockJock service tool to remove each snap ring and old internal assembly without damaging the outer body or retaining groove.
- Inspect every outer body, pivot ball, grease passage, and retaining groove; replace damaged components instead of assembling new internals into worn hardware.
- Lubricate and seat one new bushing around each serviceable pivot ball, aligning the grease passage with the joint's lubrication path.
- Install two retaining washers and one new snap ring in each joint, confirming that every snap ring is fully seated.
- Reinstall the joints, torque all vehicle or fabrication fasteners to the applicable specifications, and verify articulation and clearance through suspension travel.
- Lubricate only with non-synthetic high-moly grease and a hand-pump grease gun; stop before excess pressure can damage a joint.
