I just bought a k5 with a d60 under it, I flat towed it like 400miles with a toyota t100 and it was like perfect, no deathwoble or anything while towing. I could turn the wheels by hand with the steering wheel. The guy said he put new kingpins and brakes on it a year ago, but the truck hasnt moved since, from what i can tell hes telling the truth, the rotors and pads look brand new beside the rust. But after taking the axle off, and letting it sit around for a week, I found that i cant move the knuckles by hand or at all. I took the tierod off, one side if I really try I can move it a little, and the other side i cant even move. Is this normal or what? I know when you put new ball joints in they are pretty stiff but nothing even close to this. Oh and its not the u joints or shafts that is preventing them for moving, cuz the rotor spins freely with the hubs locked. Any ideas? I plan on selling this axle and dont want to rip someone off when i tell them everything is perfect on this axles when the knuckles wont even move.
