L2ridehd, that’s good advice. This solved a problem I had a while ago that was causing loud banging as the door rose.
For lubrication of metal to metal friction, I prefer 3 in 1 White Lithium Grease which comes in a spray can and also has a straw nozzle for directing the spray into the hinges etc.
Another test you should perform once a year or so is to disengage the opener and then raise the door up manually about half way. When you let go, the door should stay put. If it starts to drop, the springs have lost some tension. You can fix that by raising the door all the way up and then tightening the adjusting bolts that attach the spring to the door frame. Only takes a few minutes and helps to reduce the strain on the motor.
