I replaced the starter in my sister in laws automatic 2006 Civic Dx. Its a really bitch to replace, really a fucking pain in the ass. The car cranks over fine and starts great, but it makes a slight grinding noise at the end of starting cycle. It doesnt always do it, but most of the time. It seems like it is when the car starts or just after it starts. There were no shims included and the starters seem identical. I want to hope that its something that will work itself out but I have the feeling I will have to install a new one. Why would it do this?
