Applications

Tech Note 1: Hot-Forged
QU40903 is a special external snap ring type universal joint made to match Spicer 1330 series driveshaft yokes with cup diameter is 1-1/16" (26.99 mm) and Ford axle, transmission, or transfer case yokes made for 1-1/8" (28.6 mm) diameter cups. The overall width for both cup sets is 3-5/8" (92.08 mm). QU40903 is a conventional u-joint with a hot-forged cross that is suitable for most applications. For high-torque or high performance applications, see our TK40723 Premium Torque King Factory-Lubed U-Joint with Cold-Forged Cross.

Tech Note 2: Cups
For 1979-1997 Ford full size driveshaft applications, you always have to check to see if the diameter of all 4 cups are the same. On many of these Ford driveshafts with Single-Cardan (1 u-joint) yokes, you will find one of these 1330F series u-joint which have 1-1/16" diameter cups pressed in the driveshaft yoke, and 1-1/8" cups bolted to the axle or transfer case yoke. The larger diameter cups have thicker walls which are more resistant to deformation from the u-bolts that typically attach the universal joint to the gear box yoke on these older vehicles.

Tech Note 3: U-Joint Specs
More universal joints and driveshaft yokes are wrecked by slam-bang methods of u-joint replacement than by any other cause. Refer to TM3000 Driveshaft and Universal Joint Manual or TSB3502 External Snap Ring Single-Cardan U-Joint Service.
