hey guys looking to see if anyone has put in a kryptonite rear transfer case housing from DMAXSTORE.com in there lbz. they say it's made out Aluminum instead of magnesium and will last longer even with out doing a pump rub kit. seeing if any one has had any issues. i have a small vibration around 65ish. u-joints are good and put a new out put shaft bushing inn and it still vibrates. i'm thinking the rear housing out put is egged. anyone been threw this to. thanks:

 

have you had an alignment lately? or maybe tires balanced properly?

 

I did a alignment and tire balance the same time i put new tires on about 5,000 miles ago. I had the vibration before all this. i got under the truck, the out put shaft has a little up and down motion in it. i can hear a little knocking in the transfer case where the main out put shaft would sit.
