3526-20 – Ball Stud Yokes – 1350 Series – 2.000″ Tube Diameter – 0.120″ Wall Thickne

The 3526-20 ball stud yoke provides the centering socket interface for 1350 series CV double-joint assemblies. Its ball stud diameter of OEM-spec inches maintains the precise bisect angle required for velocity cancellation in high-angle driveshaft applications.

Specifications

Ball Stud Wear and CV Joint Performance

The centering socket in a double-Cardan CV joint rides on the ball stud to maintain the joint's midpoint at the bisect angle. When the ball wears below specification, the socket can drift from the true bisect, causing incomplete velocity cancellation. The result: second-order vibration at twice shaft speed that mimics U-joint failure but persists even after bearing replacement.

Replacing the 3526-20 restores the correct ball diameter and surface finish. After installation, confirm the centering socket engagement depth by hand-rotating the assembled shaft through its full angle range -- smooth, binding-free articulation confirms correct fit.

Inspection Intervals

• Inspect ball stud condition whenever U-joint crosses are replaced in a CV assembly
• Measure ball diameter with a micrometer -- replace if more than 0.005 inch below nominal
• Check for surface pitting or scoring that would cause socket wear under load
• Replace dust cover or rubber boot if equipped -- contamination accelerates stud wear significantly
