Ford Truck Enthusiasts Forums - I've been gone a long time...back with a rear diff ?

Well guys it has been quite a long time. This whole USAF thing has been keeping me out of state and country quite a bit. Anyways...

So I need to replace my rear end... I attempted to fix the leak in the sealand I guess I didn't count my rotations right and now my rear end has too much backlash...oh well she has 140k on the clock. (one good thing about the military is that it helps you reduce your mileage on your vehicles)

SO here is where I'm at. I'm going for a complete rebuild. I don't want to take the risk of junk yarding it only to find out that it is a bunk rear end. I tow toys very often usually almost all the way up to the max rating. What I need help with is brand...I will purchase the Master Rebuild Kit, and ClutchPacks to match...

Yukon High Performance

US Standard Gear

FORD OEM...

Also is there anywhere I can go to get my diff tag decoded? My ring has 373 stamped on it, so that would mean that’s what it is? As Always thanks inadvance for all your help and I missed reading these forums!!
