The lock feature allows you to manually lock the hubs if preferred. When using the Pulse Vacuum Hublock...auto...all front drive line components are disconnected...minimizing wear...and modestly improving fuel economy when in 2WD.

Sorry for nitpicking, but you have an axle on the front of your truck, not an axel. Axel was the lead cop in the Beverly Hills Cop movies, played by Eddie Murphy.
Your hubs have an AUTO position and a LOCK position. Use the LOCK position when the hubs fail to engage automatically. Eventually they will, these hubs suck.
If you have not used 4 wheel drive in a while it also wouldn't hurt to put the hubs in LOCK every month or so and drive 10 miles, just to get everything rotating and lubricated. Just leave the switch in 2 wheel drive so you don't hurt the transfer case.
