5-Screw Auto Hub Lock
These use a single thick splined shim between the C-clip & the spindle to hold the axle stub in place. Later designs used 3 washers. Install three washers in order: metal washer first, plastic washer second and splined washer last.
Before the C-washer can be installed, the stub shaft must be pushed fully outboard against the inner spindle seal by reaching behind the steering knuckle to the u-joint.
