Screeching noise and my car will hardly move...I feel like Charlie Brown!

[99CL500]

I installed Mercedes Benz Lug-Locks the other day on my 99 CL500. The locks were longer than the standard lug, but I didn’t give it much thought since it still went in, though it was quite tight (I had to torque it to get it to ‘seat’ in).

I went to move the car and it would hardly move. So I uninstalled the lug-locks and put the original lugs back in. Unfortunately, when I try to move the car the rear wheels, especially the drivers side rear wheel, makes a horrible screeching high-pitched noise along with the fact that the car moved very slowly as if the emergency brake is on. The car is difficult to move to say the least.

A couple of notes:
-I’m obviously mechanically challenged .
-I uninstalled the rear wheels to see if I could notice anything wrong but did not notice anything out of place as far as I could tell.
-I did not rotate the rotors when I uninstalled the wheels.
-The rotor/hub on the driver’s side would only move a ‘shimmy’ back and forth.
-I have subscribed to the Alldata.com but I wasn’t able to find anything that would clue me in to my problem.

Thanks for any help that you can give.
