2015 Freightliner making clunking noise when trying to start

I’ve been dealing with this intermittent starting issue with my 2015 Freightliner Cascadia. I’ve checked, cleaned and replaced battery terminals and cables. I also Volt meter tested to make sure it was getting proper Volts. Found a wire that was faulty and replaced. That solved the issue no crank no click or nothing. Not to soon after I replaced the starter. After removing the old starter and inspecting the only thing I could see was that there was a lot of play In the shaft. Recently while I was at rest stop I went to start it and it made this sound. I’ve included a video. Has anyone had this exact thing happen and what was the fix. Any and all input and suggestions is greatly appreciated. Thanks in advance.

 

Yeah we did that and the batteries were good. Would a problem with the Sam Chassis module cause an issue with starting the truck?

 

Those 4 clunks was from 1 turn of the key and holding it. When this happens..I have a cable with a metal loop tab on both ends. I’ll use it to jump the starter and let it crank for a second. Sometimes it’ll start but if it doesn’t then I go back into the cab and turn the key off afterwards and then turn back on. Let the needles sweep and crank it again with the key and it’ll crank right over. I’m thinking there has to be a short somewhere in the system that im missing. Thankfully it has never left me stranded but it’s just a pain in the ### that I can’t get to the root of the problem.
