I rebuilt my starter. It actually still worked, but on really cold mornings, the contacts wouldnt quite get it done, and I'd have to cycle the key several times. I picked up the contacts, plunger, and replacement screws here locally (Texas Alternator and Starter) for a total of 13.00. Great service. It is totally a one banana job, I didnt even have any trouble getting it off or reinstalling it. Well designed placement and product. I intended to do a tutorial on it, even have the camera set up on the tri pod, but my Son took ill, and I just didn't have the time.

the actual starter motor casing. My brushes were basically brand new. Not bad for 254,000 miles

lots of grease in the gear unit, I cleaned it up a little, but everything looks great inside.
