havent replaced them but have fiddled with them on a couple of occasions. Dont believe that it would be difficult at all. I suspect however that is unlikely that your poblem would be in the lines themselves. Most likely the pump, valve, or the seal in the hub if you are not getting any vacuum but you can troubleshoot via isolation along the lines. A golf tee works well to plug the line at the hubs

Hello... thanks for the post... What Valve are you referring too? I can lock my hubs and everything works find..
When you say that I should plug the lines at the hubs, what will that tell me?

Vacuum pump - pressure guage
hello...
I bought a pressure guage, and tested the line, pulled from the hub and when I put the guage on, and turn the 4x4 control, It sounds like a "valve" opening and closing.
any ideas?

Valve
Great... thanks.
I didn't get any "Pressure" on the valve when I disconnected the Vacuum tube from the hub.
