RockJock Johnny Joint Rebuild Kit 4-Pack (2-1/2in. Standard)

Keep Your RockJock Johnny Joints Operating Like New with the CE-9110RK-BDL-4P 2.5-Inch Standard Rebuild Kit 4-Pack

The RockJock CE-9110RK-BDL-4P is a four-pack bundle of the CE-9110RK rebuild kit for 2.5-inch standard body RockJock Johnny Joints. Johnny Joints are high-articulation ball and socket joints used in aftermarket suspension links, control arms, and track bars for Jeep, 4x4, and off-road applications. With regular off-road use, the internal bushings, side washers, and snap rings in Johnny Joints wear over time and require replacement to maintain proper joint function, articulation, and precise suspension link positioning. Rather than replacing an entire control arm or link assembly, the CE-9110RK-BDL-4P allows the joints to be rebuilt in place at a fraction of the cost of full replacement. The 4-pack covers a full set of four joints simultaneously, which is the typical quantity for a complete rear suspension link rebuild on most Jeep platforms. Compatible with 2.5-inch standard body RockJock Johnny Joints, specifically the CE-9114 and related standard body joint family.

Frequently Asked Questions

The RockJock CE-9110RK-BDL-4P is a four-pack bundle of CE-9110RK rebuild kits for 2.5-inch standard body RockJock Johnny Joints. Each kit contains the replacement bushing halves, side washers, and snap ring needed to rebuild one 2.5-inch standard body Johnny Joint back to factory specification. The 4-pack covers a complete set of four joints in one purchase.

The CE-9110RK rebuild kit is designed for the 2.5-inch standard body RockJock Johnny Joint, specifically the CE-9114 and related standard body joints in the 2.5-inch family. It does not fit the 2.5-inch narrow body joint (CE-9117N or CE-9113N-14), the 2-inch standard body joint, or the 2-inch narrow body joint. Confirm your specific joint part number before ordering to ensure the correct rebuild kit.

A complete aftermarket control arm or track bar can cost several hundred dollars. The CE-9110RK rebuild kit restores the joint to factory function at a fraction of that cost, provided the joint housing itself is undamaged. Rebuilding is the correct approach when the bushing material shows wear or the joint has developed excessive play, but the housing threads and body are still in serviceable condition.

Signs that a 2.5-inch Johnny Joint needs rebuilding include visible wear, cracking, or compression of the bushing material, lateral play in the joint when loaded, clunking or knocking sounds from the suspension under articulation, and visible deterioration of the side washers or snap ring. Inspect joints at every oil change interval or after any significant off-road event involving hard impacts or rock contact.

Four joints is the typical quantity for a complete rear suspension link rebuild on most Jeep platforms when using upper and lower control arms on each side. If you are also rebuilding the front control arms or a front track bar, additional kits may be needed. Plan your rebuild quantity based on the total number of 2.5-inch standard body Johnny Joints in your specific suspension setup.

Typically the joint must be removed from the link to properly rebuild it. The snap ring retaining the bushing must be accessed from inside the joint housing, which generally requires removing the joint from the vehicle and disassembling it on a bench. Refer to the RockJock Johnny Joint rebuild procedure for step-by-step instructions.

No. The CE-9110RK is for the standard body 2.5-inch joint only. The narrow body 2.5-inch joint uses the CE-9110NRK rebuild kit, which has different bushing dimensions. Ordering the wrong rebuild kit will result in parts that do not fit the joint correctly.

Yes. RockJock offers rebuild kits for the full Johnny Joint family including the 2-inch standard body (CE-9112RK), 2-inch narrow body (CE-9112NRK), 2.5-inch narrow body (CE-9110NRK), and 2.5-inch standard body (CE-9110RK) joints. Select the rebuild kit that matches the exact joint part number installed in your suspension components.

Installation Instructions

1. Safely lift and support the vehicle. Remove the worn Johnny Joint from the suspension arm or track bar by unthreading or pressing it out of the link body per the specific joint configuration.
2. Clamp the joint housing in a padded vise. Remove the snap ring from the housing using snap ring pliers.
3. Press or drive out the worn bushing halves and side washers from the joint housing.
4. Clean the joint housing bore thoroughly, removing any debris, old bushing material, or corrosion.
5. Install the new side washer into the housing, followed by the first bushing half from the CE-9110RK kit. Press the bushing in evenly using a press or appropriate socket.
6. Install the second bushing half from the opposite end of the housing.
7. Install the second side washer and then seat the new snap ring into the housing groove using snap ring pliers until fully seated.
8. Verify the joint ball moves freely through its full range of articulation without binding.
9. Reinstall the rebuilt joint into the suspension arm or track bar and thread or press into position.
10. Reinstall the link on the vehicle, torque all fasteners to spec, and test for free movement through full suspension travel before driving.
