零件号 2-28-22867 球头叉, 1310系列, 球头长度×直径 0.500X0.594, 备注

The 2-28-22867 is a 1310 series ball stud yoke manufactured by UDS, providing the centering interface for double-Cardan CV joint assemblies. Precise ball stud dimensions are critical: an undersized stud creates slop in the centering socket, while an oversized stud causes binding that accelerates wear across all CV joint components.

Specifications

The Role of the Ball Stud in CV Joint Systems

A double-Cardan constant-velocity joint achieves velocity cancellation through the precise bisecting action of a centering socket. The socket rides on the ball stud -- part of the input-side yoke -- and holds the joint's midpoint exactly at half the total operating angle. If the ball stud diameter is worn or the geometry is incorrect, the socket drifts from the true bisect angle, and the velocity error that the double-joint design is meant to eliminate reappears as vibration at twice the shaft rotation frequency.

The 2-28-22867 maintains the ball stud dimensions to the 1310 series OEM specification, ensuring the centering socket function operates correctly throughout the joint's service life.

Diagnosis and Replacement

Ball stud wear is often overlooked during U-joint replacement because the bearing crosses are the more visible wear point. However, the centering socket and ball stud should be inspected whenever U-joints are replaced in a double-Cardan assembly. Symptoms of ball stud wear include:

• Vibration at low speeds that was absent when the shaft was new
• Vibration that returns shortly after U-joint replacement
• Audible clunk when shifting from drive to reverse at low speed
• Visible side-to-side play in the CV joint assembly when the shaft is stationary

If dust cover rubber is specified for this application, ensure it is replaced along with the yoke to prevent contamination of the centering socket from road grit and moisture.
