I'm interested in locking the 4wd in my front end in my 98 24valve cummins 3500 (dually) with the nv4500(5spd with 4.10s)...I have friends that welded theirs but I don't really want to weld due to the fact that I do run my truck on the road very rarely...I have heard of a way to do this with a system of cables where you can lock it in or have it unlocked...is this even a good idea at all?...suggestions or ideas would be appreciated thanks guys
