Applications

Tech Note 1: U-Joint type
QU40731 is an external snap ring type universal joint made to Spicer 1350 series dimensional specifications. The u-joint cup diameter is 1-3/16". The overall width is 3-5/8". Lubricate the universal joint periodically with QU90018 Pyroplex® Plus Synthetic Grease or other quality, water resistant NLGI #2 GC-LB grease.

Tech Note 2: Diesel and V10
QU40731 cross is hot-forged, which is fine for rear driveshafts in 6 cylinder or V8 gasoline powered trucks, but if you have a Diesel or V-10 truck, we recommend you use our Torque King® Cold forged TK40719 universal joints in your rear driveshaft as hot-forged 1350 size u-joints are near max capacity for Diesel and V10 power.

Tech Note 3: U-Joint Maintenance
Service intervals for this greaseable universal joint will vary with your driving conditions and type of grease you use, but as a minimum, you should grease your u-joints at every oil change or every three months whichever comes sooner. Lube more frequently in extremely wet conditions or after submersion under water. Remember, a greaseable joint that is not regularly lubed will prematurely fail from water contamination or grease loss. So, if you and your grease gun don't get together very often, we recommend you select the more expensive TK40719 Torque King® premium non-greaseable universal joint which has an average life of 7-10 years due to its durable cold-forged cross, factory synthetic lubricant, and superior seals which keeps contaminants out.

Tech Note 4: Dana 44HD and Ford Dana 60
On Dana 44HD and Ford Dana 60 Closed Knuckle applications you will need to remove the u-joint seals and remove the grease fitting after lubing the u-joint.

Tech Note 5: 4x4 Tech Publications
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.
