lift arm problem

Have a 220-4 that I put in a lifting strain and now the arms will not raise as high as they should. If I have nothing on the arms they will go completely up (most of the time, but sometimes I can raise them by hand another 5-6 inches) but if I push down on them with my hand they go down about 6 inches and thus will not raise an implement very high ... about 2 inches off the ground with a scraper blade. Pulled lift arm control housing and adjustments seem to be correct per manual. When arms lower they fall abruptly when about 3 inches from ground ....and I hear a click inside the housing ..... any suggestions Thanks
