My Table Saw Bosch 4000 is running very slow, what should I to replace?

Bosch table saws have two weak areas. The bearings they use and the design/ construction of the field. The most common problem is the bearing on the end of the armature. It tends to sieze up. "very" common problem with that saw. Good news/ bad news. Good news is a new bearing is about $10 and easy to replace ( with the correct tools). Bad news , if you've used it for any period of time with a siezed bearing you probally melted the plastic housing that the bearing sits in and that will probally have to be replaced also. (which is a bit of a pain in the ass repair .)
if the bearing feels good ( highly unlikely ) then the field has probally overheated and will need to be replaced, another common problem on that saw.
