Shop Now for Spindle Nuts and Hardware for 1972-1993 Dana 70 Series Rear Axles in Dodge D300, W300, D350, and W350 trucks.
Spindle Nuts have two functions and they are to provide for correct wheel bearing adjustment and to keep your wheel hubs in place. We stock both the original equipment single nut and our Torque King® double spindle nut upgrade sets for your big Dodge Dana 70 rear axle. Stock Spindle Nuts and Spindle Lock Wedges are "Single Use" parts that are designed to be installed once and only once. For safety reasons, you must discard both the nut and wedge if they are removed from the spindle for any reason. Both parts lose a percentage of their resistance to coming off when they are removed. You may hear of cases where this type of factory nut has come off while the truck was being driven. Invariably, these failures involve nuts and wedges that have been reused or improperly installed.
QU40077 Spindle Nuts and QU40089 Spindle Lock Wedges are "Single Use", genuine Dodge and Dana Spicer original equipment components. These parts are designed to be installed once and only once.

You may hear of cases where this type of factory nut has come off while the truck was being driven. Invariably, these failures involve nuts and wedges that have been reused. I am not aware of a single instance of a properly installed new nut and wedge coming off like that. In my opinion, the original equipment nut design is as safe to use as our double nut sets sold above as long as you follow the rules.
