May not be the answer your looking for but I got tired of having problems with the CAD and replaced it with a cable from posilok. Problem free ever since

When you say 2-3 miles what kind of road surface are you running on. Something soft and slippery or dry and hard. If it's hard pack or something you can get by with it in two wheel drive you are really putting the transfer case and differential in a BIND in 4X4 which could cause it to kick out and bang back in. Four wheel drive is really only made to run when rear wheel drive won't make it. When you need it pull it in, when you don't push it out.
