Detailed Description

MOOG 861 is a steering shaft universal joint engineered for service on 1975-1999 Chevrolet P30 and 1979-1999 GMC P3500 applications. The joint uses round grooved bearings on both axes, with matching 0.969 in. bearing cap diameters and a compact 1.444 in. length on each axis for OE-style replacement work. Its greaseable construction and center-mounted angled lube fitting support routine maintenance access during driveline service.

What It Helps Solve

  • Steering shaft play caused by worn universal joint bearings
  • Binding or rough steering shaft movement
  • Noise from a dry or deteriorated U-joint
  • Service issues on greaseable steering shaft joints
  • Replacement needs for Rockwell L6N OE-series steering shaft hardware

Installation Notes and Tips

Verify bearing cap diameter, groove style, and length measurements before installation. This joint uses 4 grooved round bearings and is identified by outside-of-groove and inside-of-groove length measurements, so matching the original steering shaft joint is important for proper fit. Lubricate the joint through the angled center fitting after installation and during regular service intervals.

Quality Assurance

MOOG backs this universal joint with materials selected for service durability and testing focused on dependable performance. The brand’s problem-solving design approach is aimed at making replacement work more efficient and reducing installation friction on steering shaft service jobs.
