doorsnoise reduction
I have a sliding door which makes quite a loud squeaking sound when it is opened or closed. As best I can tell the sound is coming from the door rubbing against a metallic guide at the bottom as shown in the photo below.
What can I do to stop the door from squeaking?
I guess you could try putting some thin foam or felt stick on pads on the inside of the door frame where the door contacts it. This should lower the sound of the wood to wood contact. If the knob hardware is also loud, try using some dry silicon spray lubricant on the moving parts and on the door hinges. Sleep well.....
One of the adjustment screws is for the swing speed, and one is for the latch speed. It sounds like the latch speed is too high.
Adjust the latch speed until the door is just moving fast enough that it closes. You'll also want to be sure to test it by opening the door the minimum amount someone would open it.
If it doesn't shut if you slow it down at all, it may be the door arm is installed incorrectly.
If it doesn't really slow down when you adjust it, then it could be the closer is broken (lost fluid or broken valve seal) and easiest thing to do is replace the entire closer.

It looks like you should be able to adjust the "guides", if that's the case you could try just backing them off a tiny bit.
Try turning the screw looking bit, and see if you can slide the guides away from the door a bit.
