Message Just wanted to say thanks to everyone that helped me out on my post the other day about new OEM starters no longer being available.

I first checked my wiring at the ecu and verified I had nothing drawing switched power from Pin 45.

Next I pulled the starter to check the starter and flywheel teeth. The starter had no damage and almost no signs of wear. The flywheel had light wear but it was consistent through out the flywheel. At this point I no longer suspected a damaged ring gear since the grinding was random.

I pulled my starter relay(Also known as the Inhibitor relay) and ran a few test on it. I had a brand new relay to compare it to. The resistance of the relay coil matched as well as the resistance across the switch when energized at 12 volts. Both relays switched over at the same voltage. After testing I am fairly certain there was nothing wrong with the relay however, since I had a brand new one I went ahead and put it in.

Lastly, I decided to disassemble the starter and see what I could find. Right away I noticed the grease around the bendix gear apeared dried up. I got everything nice and clean using brake cleaner and re-greased the needle bearings and bendix gear.

Finally no more grinding! This issue has bothered me for so long and was getting much worse as the weather got cooler. Now I understand why.

This was a cheap and easy fix that I thought was worth posting about since the grinding seems to be a fairly common issue based on my search here.
