And more. So left tire is off the ground. It spins by hand after one revolution it gets hard to spin. I then started the truck put in gear and left wheel off the ground will free wheel . It acts as a broken shaft .Slow to start but with some coaxing will spin quite fast. When it spins the speedo registers . So that means the speedo is running from power off the back tire not the front of the trans ? what the heck..
