Faucet hard to pull on and push off

YOU ARE LUCKY, OLD FAUCETS ARE LIKE CLASSIC CARS, INDESTRUCTIBLE. YOUR INNER CARTRIDGE NEEDS TO BE REPLACED OR CLEANED. IN MY EXPERIENCE IF YOU'RE GOING TO GO THROUGH THE TROUBLE TO CLEAN IT YOU MIGHT AS WELL REPLACE IT, BECAUSE MORE TIMES THAN NOT AFTER YOU CLEAN IT, IT WILL START LEAKING. START BY TURNING OFF YOUR WATER AT THE METER, TURN THE FAUCET ON TO BLEED ANY PRESSURE AND VERIFY THAT THE WATER IS OFF. IF THIS IS THE CRYSTAL HANDLE DELTA I AM THINKING OF FOLLOW THESE STEPS: 1. REMOVE THE PLASTIC COVER PLATE IN THE CENTER OF THE HANDLE WITH A FLAT SCREWDRIVER. 2. REMOVE THE SCREW BENEATH THE BEFORE MENTIONED COVER. 3. REMOVE THE HANDLE. 4. REMOVE THE NUT BELOW THE BEFORE MENTIONED HANDLE. 5. REMOVE THE CARTRIDGE, SEATS, STEM AND REPLACE OR CLEAN. 6.FOLLOW THE BEFORE MENTIONED INSTRUCTIONS IN REVERSE MAKING SURE ALL SLOTS AND GROOVES LINE UP. TURN THE WATER BACK ON AND TURN ALL FAUCETS ON TO BLEED ANY AIR IN THE LINES.... GOOD LUCK
