Don't pull it out????
But seriously....what do you see on the sides when you pull it out? Tracks, rollers? Isn't there something that would benefit from a lubricant of some sort?
Please take a picture of the runners .. otherwise near impossible to trouble shoot
Problem fixed. When I removed the drawer to take photo, I noticed that a screw had become loose that held the track. The loud noise was the track rubbing against the wood. Tighten the screw and now no noise. Thx for the suggestions of taking a pic. Which led to the discovery.
