What Carl posted is mostly true. Sneak up on the dish. Check that the elevation lock down bolts are tight. Half inch wrench left and right side. Check the azimuth lock down bolts, bottom front same wrench. Grab the AZ/EL bracket with both hands. Shake. If it moves fix that. If everyting checks out dont worry about alighnment. You might need a rubber mallet to take the LNB out, I use my pliers(handle end rubber) to beat it out most days. Good Luck.
