Hello everyone. I've got my first experience with shimming a starter. I have a 1995 Pontiac Bonneville. Changed the starter, and it now makes a grinding noise when I try to start the car. I noticed a small flat piece of metal that fell out when I took the old starter off. I didn't think much about it, but later found out that the old starter was shimmed across both bolts. I tried re-shimming it with the shim that I had like it was, but it still grinds. I read where I might need to just shim the back bolt--the longer one away from the front of the car, but I can't figure out how to get to it. I also noticed that others take the flywheel cover off of the car to better access all of this as well. I have not done that as of yet. Any ideas out there as to how to get this fixed? This is a rebuilt starter from AutoZone, and I asked them if they had any starter shims, and they referred me to a dealer...I'm a little stumped. Any ideas out there as to how to fix this? I'm open to suggestions.
