Two parts to this, but it's all conected.
Bought my Detroit for my D30, and a buddy told me a guy he worked with could put it in, first time he put it in, he put any shims back in it, tried to give it back like that, told him no, but I needed my Jeep back before he could redo it, so he pulled both axle shafts and the front driveshaft, and gave it to me like that, and destroyed my hubs, then reinstalled the stock shims in the locker, not quite right, but he never touched my Jeep again.
So me and a buddy decided to fix my front hubs our selfs in a friends garage. We started on the Drivers side, but the guy who installed the locker wrong, used his 3/4 drive impact to torque down the axle nut in an atempt to "fix" my now seporated bearings. Sheered the square part off my 1/2 drive braker bar trying to get them off. So I packed up everything while my buddy put the wheel on while he was fighting with his wife on the phone.
Started down the road on the way to my Dads to use his compressor 45 minutes away, and noticed a growling noise from the front, thinking that it was the hub about ready to go, I kept driving praying that it held till we got to my dads and could fix it. Finally got to my dads and pulled into my the shop, got out and saw that all 5 lugs were incredably loose and the holes in the wheel were wallered out to the point, I didn't need to remove the lugs to get the wheel off, just jack the Jeep up and it fell off.
I don't let that buddy work on my Jeep anymore, and I ignore his suggestions on guys to work on my Jeep.
