9" rear end problems
So I have a 3.50 9" rear end. The 3rd member is new. After installing my new driveshaft and driving for about a day, I started hearing a squeaking. Almost sounded like birds chirping. I thought maybe the u joints didn't get geased at the machine shop, or maybe the caps were seated to far. Drove to my mechanic to grease them and on the way the chirp turned into a a thump or grind, thought great I destroyed the needle bearings. Then I came to a stop, and then couldn't take off. First thought was my driveshaft might have slung again, but it was still in. Put the truck in gear and the driveshaft spins, so I'm assuming I broke the axles, the 3rd member seems to still be intact ( haven't tried to open it) so if it is my axle shafts what are the chances the 3rd member is roasted?

If you were just driving around normally, and not hammering on the truck, I wouldn't suspect the axle(s) are broken.
Is the differential open (single track) or, does it have a Traction-Lok?
Even if the truck had a Traction-Lok and the clutches went away (burned up), the right axle would still propel the truck, it would just act like an open differential.
By your description, the most recent change to the rear end was the 3rd member. This may seem overly simplistic but, is there gear oil in the rear end?

I guess I should have said "new" because it's not new to me. In a previous post I mentioned this. There is a guy near where I live that has a ford graveyard long story short, he bought a chassis that some had started as a project. I bought the rear end out from under it which was suppose to be new, the third member anyway. I was drive normal yes, and I pray to god there was gear oil in it or my mechanic is paying for it. I payed him to put the rear end in it, gear oil and all.
