This is from an earlier post I made
If it only grinds sometimes, or a little after the starter is replaced, it's most likely the flywheel. What year and engine do you have? If your car is a V6 that is a 1998 or 1999, and possibly some earlier years then you are most likely up for a fight. I had this problem with my 1998 mystique, and it was a pain. I got ford to fix it for next to nothing, pm me and ask how. Here is a PM I sent to another CEG'r
Hey, this is red99sesport here.
I got your Private Mail, and I try to help as much as I can. First I'll tell you what my car did exactly. One day in December of 2001 I went to start the car, a 1998 Mercury Mystique Duratec V6. It would not start, the starter made a whirring sound, or as you described the same noise the car makes when you turn the key and it's already started. Anyway, it started after turning the key several more times, and holding it for longer than usual.
I thought nothing of it, because it only did it twice in December, and then didn't do it anymore until March. Then it started doing it almost every time I got in the car. I took it to my stealership, they told me my starter and solenoid were bad. They replaced them for $400. After four days, they called me to come and get the car. When I got there, it would not start. Same noise and everything. I was truly pissed. So, I drove the car home, and parked it. Then I went to
www.nhtsa.org and searched for a Technical Service Bulletin.
I found one, and took it to my stealership. They took it, and told me no such TSB existed. I got it from the Federal Government, so I knew they were lying. I insisted they check the gear that the starter turns to start the engine. They did, and by god, it was warped. It looked like a potato chip. They replaced it in five days, and for two-thousand some dollars, but Ford payed for almost all of it.
Here is a copy of the TSB, I think you can search by TSB number on the site if you want more.
Make : MERCURY Model : MYSTIQUE Year : 1998
