140-28-17U -- SPL140 Series Weld Tube Yoke

Weld tube yokes are the u-joint-end connection for custom driveshaft tubes. The 140-28-17U is a SPL140 series weld yoke for 4.331x0.197-inch OD tube with listed-inch wall, with a butt diameter of 3.957 inch and a CJ-to-weld distance of 3.500" inch. Universal Driveshafts supplies this part for applications where the stock component is no longer available from OEM channels or where a custom build requires a proven off-the-shelf solution rather than a machined one-off.

Technical Specifications

Component Function in the Drivetrain

The weld tube yoke is not a glamorous part, but it is load-critical. Every pound-foot of engine torque passes through it on its way to the wheels. A worn, cracked, or dimensionally incorrect weld tube yoke introduces vibration, unbalances the shaft, and accelerates wear on adjacent components including the u-joint cross, differential seal, and output shaft bearing. The 140-28-17U replaces like-for-like with current production tolerances.

Installation Notes

• Verify tube OD 4.331x0.197 x wall listed, butt dia 3.957 matches your application before installation
• Inspect mating components (transmission tail housing, output shaft) for wear before fitting
• Lightly lubricate splines or pilot with assembly grease -- do not run dry
• Confirm SPL140 series u-joint cross is seated fully before tightening retaining hardware
• Check for vibration on first road test and address any anomaly before extended driving
