97 TXT gas starter issue

[Wlong1957]

I have a 97 txt ezgo gas car. Last December I had starting issues and determined that the brushes were worn. I replaced the brushes. All was well until last night ( 9 months later)

After a 2 mile tow home. Everything checked out. No broken wires, solenoid clicking ect... Finally tapped on the starter with a hammer and starts right up.

I haven.t inspected the 9 month old brushes yet . But the question is could their be another issue with the starter that tapping with a hammer temporarily relieves?

I would think it would be unlikely that a new set of brushes would wear out after 9 months

Any advice would be appreciated
