I think that's what I would do.

I'm thinking of buying one of these once I determine what my exact ration percentage is. I've measured it with my wife going behind me on gravel road (

but no license plates yet) and at first it was off 15mph. I put a different gear in and now it's app. 5mph.

But, it may be more or less once I get it checked out correctly.

All I've figured out so far is it isn't really for just the four wheel drive it was either to make the ratio adjustment easier ..cause it was off board. Or someone changed the gear ratios so much they had to put this on the outside to change it.

Ha I'm fixin to change the tire size too so I guess it won't matter. Alot of the threads I saw last night said a speedo shop could adjust the gears in it.

Was Your Speedo Correct Before It Fell Apart? You Can Remove It And Your Cable Will Fit Direct Into Your T Case. Mine Did Because I Looked For Daus And Couldnt Find One So I Went Streight In. My Truck Is A 3/4 Ton W/410s. Its Within 2 Mph Of My Wifes Nw Envoy

Thanks guys I'll try it both ways

. All of those pages I found said it was for a situation where you couldn't get enough ratio change (by changing the ones in you T-case or Tranny) because you had had put some really low gears in the diffs.
