QU40764 Greaseable 7290 x 1330 Series Conversion U-Joint with 2 External and 2 Internal Snap Rings. QU40764 is a Hot-Forged, Alloy Steel, Greaseable Front Universal Joint that is most commonly used to replace the original 7290 x 1330 conversion universal joint used by Dodge to join the 1330 Series Driveshaft Slip Yoke to the 7290 Series Pinion Yoke in very late 1998 to 1999 Dodge Ram 1500, Ram 2500, and Ram 3500 4x4 trucks. (QU40764 has 2 external snap rings for the slip yoke and 2 internal c-clips that fit against the inside of the pinion yoke).

Applications
Tech Note 1: Conversion Note 1
This is a special conversion universal joint used to adapt a driveshaft with a slip yoke made to external snap ring Spicer 1330 specifications to an axle with a pinion yoke made to fit Detroit Universal 7290 series internal c-clip u-joints. Spicer 1330 external snap ring universal joints have 1-1/16" diameter cups and have a 3-5/8" overall width. Detroit 7290 internal C-clip u-joints have 1-1/8" diameter cups and fit yokes with an inside measurement of 2-5/8".
Tech Note 2: Conversion Note 2
The only original equipment use I know of for this special conversion u-joint was by Dodge for the front driveshaft to front axle coupling on early to mid production 1999 full size Ram 4x4 trucks. It can also be used for retrofitting any other Dodge application that requires coupling a 1330 series yoke to a 7290 series yoke such as when replacing the factory slip yoke on 1993-1998 4x4s with QU40701 Slip Yoke.
