Thread: Full extension ball bearing drawer slides problem

Thats a strange one, each runner would have its own soft close mech which don't wear out. If the locking devices are plastic one or both may have broken. The first thing i would do is check and see if the runner mounting holes are elongated, if so dropping the back of the runner by a hair may cure the self opening issue.

Thank you... I'll check on that.

I'm almost certain there was no soft close 20 years ago.

Ball bearing slides generally have a resistance built into them to stop them from simply rolling out... It's usually a rubber stopper, for lack of a better word. Being that they're 20 years old I'd be thinking they're a bit worn out so they just roll out. That particular drawer may have been put in so it slants forwards just enough for it to creep out. Changing the angle so it inclines back will keep the drawer in. Best though to replace the runners. Should be able to use the old holes. Home Depot should have them.
