Applications

Tech Note 1: Pin Must Line Up
The pin pressed into the outer face of this Inner Spindle Nut MUST line up with one of the holes in QU40164 Spindle Washer. If the pin does not line up with a hole, try to reverse the washer. If the pin still does not slip into one of the holes, remove the washer and make a slight adjustment of the nut which will do the trick.

Tech Note 2: Matching Lock Washer and Outer Nut
Also see QK4729 Spindle Nut Set which includes QU40166 Inner Nut, QU40164 Spindle Nut Lock Washer, and QU40163 Outer Spindle Nut.

Tech Note 3: To Adjust
Adjust this nut with QT1018i or QT1110i Spindle Nut Wrenches to the specification listed in the vehicle manufacturer Shop Manual applicable to your vehicle. The wheel bearing adjustment procedures will vary depending upon year, make, and hub lock type. For trucks with 4 Slot Double Spindle Nut Sets (QK4729) and automatic hub-locks, check out our optional, heavy-duty, QT1110i High-Torque Socket which can take the higher torque specifications called for on  auto hub equipped trucks. Both QT1018/QT1018i and QT1110/QT1110i series sockets work equally well on axles with manual hubs. The open lug design of QT1018/QT1018i is the better choice when working on an axle that some previous person used a chisel on the nuts instead of a socket as the raised burrs will not affect the socket engagement.
