I just want to thank you for not being another video with the same lower spray arm that says "It just lifts out easy by pressing a tab." Probably 200 videos about numerous makes and models all with the same lower spray arm and almost no videos willing to admit the existence of anything that isn't this easy lower spray arm.

Is there a way to tell if it's broken? My just doesn't spin very smooth (kind of wobbles when spun by hand). Thanks!

[@PartsDr]

You will usually see something broken or clogged on the spray arm. They normally kind of wobble when spun by hand, so that probably isn't anything to be concerned about.

What screws should I get/use? I misplaced the ones for the lower arm

[@PartsDr]

If possible, you will want to find the original LG screws or something very close to them. They are usually a stainless steel screw that won't rust.
