what concerns me is the front locker detroit ez-locker. On pavement, with the hubs locked and in 2WD, the front shimmies and dances with lots of clicks at about 3-20mph going straight, haven't gotten faster, it gets worse, but stops clicking on a turn. Off road I don't notice anything, until of course the 4WD is engaged. Can I drive this thing with hubs engaged 2WD for like a mile trail to pavement to trail with all the clicks or is something going to become destroyed? Is the noise comming partly from the axles?
The locker you have is a wratcheting type locker. This type of locker will allow one tire to travel farther than the other (in a turn) when its not under power. The clicks you hear are from that wratcheting action.
The "shimmies" I can only imagine are caused when the locker eguages/catches (because you have the hubs locked) which makes your front tire want to pull to a straighter line at speeds. Not generally a problem unless your on an icy road or going fast.
With your hubs enguaged your locker will make the truck behave as though you are running in 4hi except that the action of the locker is less predictable. Yes at higher speeds you can hurt things running that way, moslty in corners when the locker will want to catch.
