that was my first thought but without a load and spinning it by hand no noise, I jacked it up put in neutral and spun it forward and backward by the wheels and with the driveline no noise, also tried all the gears and reverse various speeds and no noise without a load, then I drove it down the street and I could have sworn it was the transmission even called and got a price for a used one then went back out and checked it again and concluded it's probably not the trans. weird..100% sure it's not the rear end, like a busted Gov-Bomb?
