Motor noise When the motor turns off it makes a loud clunk and screach noise. We have cleaned the coils, and tried to relevel it but the noise still persists.

You can remove the lower back cover panel and visually see the compressor and fan. Check the mounting bolts on the compressor to see if they are loose allowing the compressor to bounce around in there. You can also "stall" the fan with a wash cloth to stop the blade from turning (it's OK just try not to bend the blades). That will eliminate the fan squeaking as it coasts down to a stop. Better to stuff a wash cloth in while the fan isn't running. Turn the t-stat up to colder to force a run condition for a minute or two then turn the t-stat down and watch the compressor and listen for those sounds again.
