On my Warn lockout hubs, there is a spring, but it is inside the hub mechanism and you would never really see it on normal lockout removal. I believe stock lockout hubs often used a different construction that had springs that got removed separate from the hub itself. When putting my hub together, I slide the hub/rotor on with bearings and seals, install the inner wheel bearing nut, then the keyed washer and align it with the pin on the inner wheel bearing nut (after being torqued and then backed off a touch), then the outer wheel bearing nut. Then the Warn hub inner piece is installed with the large snapring and then small snap ring is installed on the outer axle shaft. Finally, the lockout hub cap is tapped in place and the long small bolts are threaded into the Warn hub inner piece. Job finished. No big coil springs to actually install anywhere. The coil spring in the Warn hub inner piece is normally already in that subassembly with no need to do anything with it. Jeff
