Shop now for Spindle Parts for some 1980-2018 Ford E450 Super Duty Vans with Dana-Spicer Model 70 or 70HD Rear Axles.
Safety Note: QU40077 Spindle Nuts and QU40089 Spindle Lock Wedges are "Single Use", genuine Ford and Dana Spicer original equipment components. These parts 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 loose 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. 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.
