tangs on end fittings, damaged or missing snap rings
and rotating bearing cups.

the component is necessary.

Take hold of the end fitting with both hands.
Try to move it vertically and horizontally to feel
any looseness.
• There should be less than .006” movement in the
U-joint relative to the end yoke. If looseness in greater
than .006” the U-joint should be replaced.
