Thanks bud, but I am quite sure it's nothing like that. I've been taking wheels off and putting them back on for decades, and do them in the same fashion as you suggest. I've never ever had a problem like this!
When I replaced the rotors last year the car was pulsating because I had been taking it to the dealer, where they always use that damn air wrench and apply uneven torque - that's what warped the OEM rotors. I have never warped rotors with my manner of doing it. They are not warped since I have no pulsating. What I have is a vibration that shakes the entire vehicle. I thought the rear calipers may have seized so I purchased a rear caliper turn and squeeze tool set and have squeezed the pistons. They squeezed fine, fairly easily, but I did notice that a fair bit of dirt and rust dust came off the area around the piston seals, so I thought by freeing that up, perhaps the vibration would be gone (i.e. perhaps the pistons were not seized but not working smoothly enough with all that crud around the seals). Well the vibration is still there. When I rotated the rotors by hand they looked like they were spinning quite nicely, no significant variation on the edge of the rotor. The tires are evenly worn and there is no vibration unless I am applying the brakes!
So I am thinking more and more that the problem is tied to the clunking noises, whatever that may be.
