2000 silverado front end binding

I am still working on this POS. I replaced a bad front differential in this Chevy 1500 because it was banging and grinding. I put a used one in and it was making noise and binding even in snow. They gave me another one and it is no different. The bind is so bad that from a dead stop with any turning of the wheel it feels like something is going to break. If I let of the gas while going slow with the wheel turned the truck will stop as if the brakes are on. If i shift to 2 hi without touching the gas it will immediately start rolling. This isn't the normal bind of a 4wd, it is severe. The salvage yard insists it is the correct gear ratio, but I am wondering, although the odds of them being wrong twice isn't likely. Any ideas ?
  • can you get at the ring gear and pinion to count the teeth to make sure they are the same?
  • Have you checked your CV joints for wear and binding?

    I'm sure these things are expensive but for something this important and difficult to install I'd only put in a new one.
  • This is strange. It sounds like you are aware that binding and bucking is normal when turning on dry pavement in 4wd, but it shouldn't make noise. It would seem that if there were different gear ratios front to rear it would bind also when going straight in 4wd. One thing I know that can make a popping noise when turning in 4wd is a bad cv joint.

    No binding going straight, but growls when slowing to a stop. I am wondering if I got two bad differentials. Maybe carrier bearing bad ? That or wrong gear ratio.I am honestly at a loss.
  • Transfer case issue.
    Does your rig have electric shift or manual/ If manual it could be linkage out of adjustment. Electric it could be the solenoid.
    What happens when you shift to 4Low?
    What about shifting to neutral if equipped/
  • Will bet that the ring gear and pinion is different ratios frt. to rear, if it will free wheel in 2 wd and seem to lock up in 4x4 then they are trying to turn @ different speeds
