Ford 9inch install help

[79longroof]

Hey guys, so I've got a weird issue.
I'm completely new to the Ford 9inch and just installed a new one from Quick Performance into my 79 Malibu Wagon.
Car is an turbo LS and 4l80e swap in progress.

Put together the rear end like it should be (according to everything I found online anyway) but it's very possible I made a mistake.
The rear axle DOES NOT want to turn now. And each axle and the pinion spun free before hanging it in the car. Was trying to push the car back into my garage and it would barely budge. There was an awful noise coming from the rear end when it would move (Which was a couple of inches total tops). I ended up putting the rear of the car on dollies to move it back into the garage for the night.

I'm guessing I have some sort of binding going on? I have no idea. I made sure the axles where in the splines before seating the bearing. The brakes and driveshaft are also unhooked. Anyone ever have a similar problem?

If you have a locker and was trying to turn the car it would act that way.

Tires rubbing?

Brakes dragging?

Watching this post. I to have been looking at Quick Performance 9" to replace my 81/2 GN.

The brakes are not connected yet. Just stuck the rear end in to move the car around. So brake drag is not possible. But thats exactly what it acts like.
Tire rubbing also not the issue. Checked for that.
Car was moving straight. No turning.

It also just has a trac-loc. No locker or spool

Jack the rear up and see if one side will turn. Not sure how that track-lock works ?Look at you're pinion and make sure nothing rubbing that. Check around the wheels and hubs for something rubbing. Just trying to help . Look for the easy stuff first.

And each axle and the pinion spun free before hanging it in the car.

I would first look for any obvious exterior binding and after that I would remove one axle at a time and try turning the pinion each time to see if it frees up and then I would remove the third member and carefully inspect that, maybe a pin or clip backed out and is stopping movement. The main thing would be to isolate why and where the binding is happening.

Just because the brakes aren't hooked up doesn't mean they aren't locked up.

As 565bbchevy mentioned, take one part off at a time and re-check. My money is on a brake catching the side of a drum or similar with a rotor. I'm guessing that when it was spinning freely on the ground you didn't have any rims/wheels bolted on.

If I'm wrong, then I'll buy you a cold one
