1963-1996 C2-C4 Half Shaft Greaseable U-Joint 374246 - OEM Number(s) (374246)

Keep your Corvette's rear suspension smooth and reliable with this greaseable half shaft U-joint, designed for 1963–1996 C2, C3, and C4 models. This component ensures optimal performance by allowing for regular maintenance and reducing wear.

Why It's Essential:

The half shaft U-joint is crucial for transferring torque from the differential to the wheels while accommodating suspension movement. A worn U-joint can lead to vibrations, clunking noises, and potential drivetrain damage. This greaseable design allows for periodic lubrication, extending the life of the joint and maintaining smooth operation.

  • Material: High-strength steel with precision-ground bearing surfaces

  • Design: Greaseable with included grease zerks for easy maintenance

  • Includes: Grease zerks and circlips for installation

  • Installation: Designed for a precise fit; professional installation recommended

Installation Tip:

When installing the new U-joint, ensure all mating surfaces are clean and free of debris. Use appropriate tools to press the U-joint into place evenly, avoiding damage to the bearing caps. Regularly grease the U-joint through the provided zerks to maintain optimal performance.

Maintain the integrity and performance of your Corvette's drivetrain by replacing worn U-joints with this high-quality, greaseable component. Order now to keep your classic Corvette running smoothly and reliably.

Tech Tip: To check your U-Joints put vehicle on jack stands or a lift put the vehicle in Neutral and from under the car rotate drive shaft or half shaft while watching U-Joints for excessive play. Also any time red "dust" is apparent on the U-Joint they need replaced. The red dust is powdered rust.
