Has anyone had to change arbor bearings on a Dewalt Chop Saw.My saw is 15 years old and has cut alot of wood over its lifetime and I noticed blade marks on my miters that make it seem like the blade has some side to side movement during the cut.The blade does feel like it can move more than it should,but I never really checked it before so I don't have a comparison.I'm wondering what kind of PIA it might be.Thanx
