Well I'm in the eastern corner of MAINE,and this was done 8/2015,shipping for a complete rebuild kit for the rear & lock right plus a ring & pinion set ,with my third was $60 to Trail Tough.They get $75 per hour(as of 8/2015) and took them two hours to not only set up the lock right but a new set of gears (5:85)&new bearings for $150 plus $58.76 return shipping.If I remember right the turn around was aweek. Truly worth the cost as you will destroy R & P sets if not setup right.Plus the Lock right was completely setup too.I was so happy I sent them the very same items for the front diff too. I have a cast steel front housing so everything weighted in pretty much the same.The cost for the front unit setup ($150)plus shipping $55.60 as I removed the stock R & P and so cut a few pounds off the box weight.I still have both sale receipts from them so,this isnt a guess. I totally understand most guys will scoff at these prices.For me,I thought it a wise investment plus the "piece of mind" that the diffs are setup by Pro' s, made it that much easier to wheel alone or be the trail breaker..lol
