FAQ
What is the CE-9111RK?It is the internal service kit for a standard-width 3-inch Johnny Joint body, with two interlocking bushings, two retaining washers, and one snap ring.
Which Johnny Joint body accepts this kit?Use it only in a standard-width 3-inch Johnny Joint outer body measuring 2.47 inches wide, whether the body is forged or weld-in.
Will it fit a narrow-body Johnny Joint?No. Narrow-body joints use different internal components, so confirm the 2.47-inch standard body width before ordering.
What is the outside diameter of each bushing half?RockJock specifies a 2.535-inch outside diameter for each urethane bushing half.
How do the two bushing halves work together?The identical halves interlock, forming a grease channel with distribution holes around the joint internals.
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 over-greasing can damage the joint.
Is the complete Johnny Joint included?No. This package contains the internal rebuild pieces only; the outer body, pivot ball, grease, and service tool are not included.
Which service tool applies?RockJock identifies its CE-9111T Johnny Joint tool for servicing these components.
Installation Instructions
- Confirm that the existing joint has a 3-inch outer body and the 2.47-inch standard width; do not install these internals in a narrow-body joint.
- Verify the package label and manufacturer part number CE-9111RK before disassembling the joint.
- Support the suspension safely, remove the joint according to the vehicle or fabrication service procedure, and clean the work area.
- Use the applicable RockJock service tool to remove the snap ring and old internals without damaging the outer body or snap-ring groove.
- Inspect the outer body, pivot ball, grease passage, and retaining groove; replace damaged components rather than assembling worn or distorted parts.
- Lubricate and interlock the two new bushing halves around the serviceable pivot ball, then seat the assembly squarely in the compatible outer body.
- Install both retaining washers and the new snap ring, confirming that the snap ring is fully seated in its groove.
- Reinstall the joint, torque all vehicle or fabrication fasteners to the applicable specification, and verify unrestricted articulation and clearance.
- Lubricate only with non-synthetic high-moly grease and a hand-pump grease gun; stop before excess pressure can damage the joint.
