EMPI CV Joint; Rear | 87-9469-B

This EMPI high-performance constant velocity joint is built for demanding driveline applications where strength, smooth power transfer, and wide-angle articulation are important. Designed as a Porsche 930-style CV joint, it features a 108mm outer diameter, 28-spline inner race, .875" balls, a solid outer race, and a Chromoly cage for added durability under high horsepower and high torque loads.

EMPI CV joints are proven in severe off-road and performance use, where the drivetrain must handle repeated suspension movement, high load, and aggressive power delivery. The hardened alloy inner and outer races are precision-machined and ground, then inspected to help provide consistent fit, smooth operation, and long service life when properly installed and lubricated.

What a CV Joint Does

A CV, or constant velocity, joint allows an axle or driveshaft to transfer power smoothly while operating at changing angles. Unlike a basic universal joint, a CV joint helps maintain consistent rotational speed through suspension travel and steering movement, reducing binding and helping deliver smoother power to the wheels.

CV joints are commonly used with independent suspension systems, performance axles, and driveline setups that require a wide operating angle. They help the axle shaft follow road or terrain movement while maintaining traction and driveline smoothness.

Installation and Maintenance Notes

CV joints require proper grease lubrication to prevent overheating, excessive friction, and premature wear. Always use the correct CV joint grease and inspect the surrounding boot, flange, bolts, and axle hardware during installation. If the boot is cracked, torn, or leaking grease, it should be replaced and the joint should be repacked before use.

Depending on the vehicle or axle assembly, replacement may involve unbolting the CV joint from the flange, servicing the boot and grease, or rebuilding part of the axle assembly. Always verify fitment, spline count, bolt pattern, and hardware requirements before installation.

Common Signs of CV Joint Wear

• Clicking, clacking, or popping noises during acceleration or turning
• Grease leaking from the CV boot area
• Vibration from the axle or driveline
• Binding or rough movement when the axle angle changes
• Visible boot damage, cracks, or missing grease

Recommended Inspection

Before installing this CV joint, compare the old joint to the replacement and confirm the 108mm outer diameter, 28-spline inner race, six-hole mounting pattern, and 10.4mm mounting hole diameter. Inspect the mating flanges, axle shaft splines, boots, clips, bolts, and washers. Replacing worn hardware during service can help prevent looseness, vibration, or premature joint failure.
