Mark at ProGear was great to do business with! I have never beard such a quiet set of gears, especially since the gear ratio is 4.88 with 32" tires! I would recommend these guys to anybody!
Thanks for the info. Going to see about checking them tonight via the fill plug. Mine a daily driver. So down time would not be good...I got to the point that I was checking the bolts before every trip to make sure they were still where they were supposed to be. You can see them with a flashlight when you pull the filler plug off the back off of the rear end. I inspected mine before my new years trip and all of the bolts were in place.
I only drove the truck for 2-3 hours after inspection before the bolts backed out:first:
ANYBODY WITH A DETROIT LOCKER IN THEIR TACO/TUNDRA SHOULD INSPECT THE BOLTS THAT HOLD THE CASE HALVES TOGETHER.
