Looked at an 07 this weekend and the sled was nice but when the guy cranked it over, there was a grinding sound and did it again when he shut it off. I immediately thought starter although he played dumb. I had not heard of any issues with these. My question is, is it likely the starter or could it be an issue with flywheel? Idled nice and I am sure its the starter but wanted to hear of any related issues before I do anything.
