My cousin has a 76 Ford F-150. Comes with a 9 Inch read end. 4 speed with 4 wheel drive.
So he is driving down the road the other day and he hears a clunk in the drivetrain, but he doesnt know where it came from. Then the truck would it go anywhere. He pulls off to the side of the road. And locks in 4 wheel drive and creeps home. The truck will not go anywhere in 2 wheel drive. I believe it is the rear end. But I was thinking it could be the transfer case as well.
I am going to check fluids today. But what do you guys think it is? Rear end or the transfer case?
Also. I need some help finding a stock differential for the truck. I have found many diffs, but they are all modified racing diffs. Anyone know where to find one?

Pull the drive shaft and try to turn the flange on the transfer case and the flange on the rear, if either one freewheels it will be in that unit. Parts are easy to find. I work for a salvage yard in Md and I can get you the parts. Call me Dave 1-800-441-5746.

definately sounds like you lost the rear end. the 9" is real easy to work with tho fortunately! you wont really need to remove the housing to completely replace the inner workings. just remove the rear brake drums and ul see 4 bolts retaining the axles. remove those on both sides, the axles slip right out! then the bolts holding the carrier in place under the truck. all the guts are now out. see what broke and replace with stuff from the junkyard. just be damn careful to make sure you got the exact same ratio going back in as coming out or you will tear all sorts of shit up in 4 wheel drive!!!
good luck!

how do I tell the difference between the ratio? Specifically what is on the truck now? I cant seem to find that information on the net.

Put a chalk mark on the tire, and on the driveshaft (like on the top of them so you can measure). Count how many times the drive shafts spins per 1 tire revolution. Thus is your gear ratio

to find the gear ratio just start counting teeth, ring gear to pinion gear. or on the (big) ring gear there might be some numbers on it.. take your wheels off and then pull them four bolts off at the back and the axles pop out. once they are out you can take the center section off. what most likely broke is the spider gears. if they broke then you will not need to get new gears. you will most likely have to shim it back together when you get all the parts fixed.
