Check inner joint Removing: Disassemble the joint to replace badly soiled grease or if the contact surfaces of the balls must be inspected for wear and damage.

–  Rotate the ball hub and ball cage. –  Press out joint part in -direction of arrow-. –  Successively press out the balls from the cage.   Note The ball hub and joint piece are paired. These are not interchangeable.

–  Tilt the ball hub out of the ball cage over the ball bearing track -arrows-. –  Inspect the joint part, ball hub, ball cage and balls for small broken out depressions (pitting = point corrosion) and seizing marks. Load alteration shocks indicate too much torsional clearance in the joint. If this is the case, replace the joint. Smoothing and bearing marks do not justify a joint replacement. Installing:

–  Insert the ball hub in the ball cage over the two chamfers. The fitting location is random. Press the balls into the cage. –  Insert the hub with cage upright into the joint part.

t  When inserting make sure the greatest distance -a- on the joint part is close to the short distance -b- on the hub after it has been swivelled in. t  Chamfer on inner diameter of the ball hub (serration) must point towards the largest diameter of the joint part.

–  Swivel in the ball hub, to do so swivel the hub out of the cage -arrows- until the balls are at bearing track distance.

–  Lock the hub with the balls into position by exerting considerable pressure on the cage -arrow-.
