3190-1006 – CV Joint Kit – 25 x 0.985″ Splines – Inner Race Width 39mm – Outer Race Width 42mm

CV Joint Component 3190-1006 -- CV Series Application

Constant velocity joints maintain a uniform output speed regardless of the operating angle between the input and output shafts -- a critical requirement in front-wheel-drive axles, independent rear suspensions, and two-piece driveshafts with high angle changes. The 3190-1006 is a CV series CV joint kit or component, with 25 splines at 0.985-inch diameter, supplied by Universal Driveshafts for replacement and custom applications.

Technical Specifications

Why CV Joint Condition Matters

A worn or incorrectly assembled CV joint produces clicking noise during tight-radius turns, vibration at specific speeds, and in advanced stages, popping or grinding under load. These symptoms mean the ball grooves, cage, or inner/outer race have exceeded their wear limits and the joint can no longer maintain velocity uniformity. Replacing with the correct part -- the 3190-1006 for this series and spline configuration -- restores the original performance characteristics.

Installation Considerations

• Pack the joint fully with CV grease before closing the boot -- under-greasing is the leading cause of premature CV failure
• Verify spline count and diameter against the shaft: 25 splines at 0.985-inch diameter
• Snap ring or circlip must seat fully in the groove -- a partial snap ring engagement allows axial movement under load
• Do not exceed the joint's rated operating angle -- exceeding it even briefly accelerates wear at the ball tracks
• Inspect the boot for damage after installation before completing reassembly
