Applications

Tech Note 1: To Grease
Axle u-joints of this size can not use a regular zerk fitting in the cross or cup due to clearance issues. To overcome the clearance problem, this quality, USA made u-joints have one of the cups drilled and tapped for a screw in flush fitting. A Needle type grease gun adapter such as our QT9405 is needed to lube the joint. To grease the left axle u-joint, first turn your front wheels all the way to right to open the maximum space at the back side of the axle joint area. Next, rotate the axle shaft so the flush fitting is access able, and then clean any crud from the fitting and grease! Use the same procedure for the right side, but turn your front wheels to the left.

Tech Note 2: Grease Fitting
In most applications, the grease fitting can not be installed in the cross until after the axle shaft is installed in the axle housing due to limited clearance between the axle shaft and steering knuckle. The grease fitting features a spring loaded poppet ball to prevent contaminants from seeping through the lube channels. The fitting is all threaded right to the head so it will have full thread contact in the thin wall cap when installed. This is important, as many competitive joints use partially threaded fittings with little or no thread contact with the cup when installed.

Tech Note 3: Grease Schedule
Service intervals 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 which ever comes sooner. Lube more frequently in extremely wet conditions or after submersion under water.

Tech Note 4: U-Joint Specs
The cup diameter for these u-joints is 1-3/16". The 4 cups are grooved to accept Inside C-Clip Snap Rings. The installed Clips fit against the machined inner faces of the axle shaft yokes. The distance between the inside of the axle shaft yoke ears must be 2-3/16".
