54mm Socket
54mm Socket

Our 54mm Socket featuring ½" ratchet drive was designed just for removing and reinstalling the 54mm spindle nuts. This is an important tool for servicing and maintaining your solid axle front end. Many of the front axles we build require a new pair of spindle nuts because the previous R&R had been with screw drivers or chisels as the spindle nuts R&R tool. This improper use leaves the spindle nut with deep gouges and prevents proper preload for the wheel bearings and outer spindle nut torque. It’s impossible to correctly service your wheel bearings with just a screw driver or chisel. The FSM calls for 6-8 lbs of preload for you wheel bearings and the outer spindle nut being torqued down to 34 ft-lbs.
