I pulled my 40 forward to install new wheels & tires and once I was ready to reverse the vehicle back to its parking spot it would not move. I jacked up the rear and the wheels spin freely in neutral, I tried putting in in reverse and forward and nothing moves, I can't get it to budge either way while in neutral either. I was thinking it's the emergency brake. the emergency brake is on the back of the transfer case, So I was wondering if the E. brake cable or a spring broke would it lock it up? I just need to move the 40 back. Any advice would be greatly appreciated, Thank You in advance...
