Generally when you purchase a starter - depending on the application- it will come with a small thin metal rod that is used to "guage" the proper distance between the bendix and the flywheel. More often than not the starters purchased these days are not necessary to shim or even worry about clearance issues. If the vehicle starts and the starter does not stay engaged too long or does not make a lound whining sound then there is no clearance problems.
The starter is probably not aligned with the flywheel. The clearance between the starter and the ring gear needs to be checked.

You shim the starter motor if there is inadequate clearance between the starter drive and the ring gear. You can check the clearance by prying the starter drive out to the ring gear with a screwdriver to see if the gears mesh properly.

Modern starters include: * the starter motor... a motor * the solenoid, which engages the electrical current to the starter AND engages the gear to the flywheel. * the bendix, which is a gear that engages the starter to the flywheel.
Remove the starter and inspect the ring gear on the flywheel.
Bad starter, bad flywheel/ring gear, bad starter/flywheel alignment.
First check for loose mounting bolts at starter. If everything is OK, then remove starter and check for broken teeth on starter pinion gear and flywheel.
A grinding noise after replacing the starter on your 1997 F-150 could be due to improper alignment between the starter gear and the flywheel, often caused by an incorrect starter installation or using the wrong starter for your vehicle. Additionally, the starter gear may be engaging with the flywheel too aggressively or may be damaged. It's also possible that debris or worn components in the flywheel are contributing to the noise. It's advisable to double-check the installation and inspect the flywheel for any issues.
The starter drive gear will be too close to the flywheel, causing a grinding noise when the starter is engaged.
Usually, the engine flywheel. A solenoid in the starter moves the starter pinion shaft forward (or backward depending on how it is mounted to the engine) to engage the outside edge of the flywheel (which has teeth to match the pinion gear).
The noise is the teeth on the flywheel grinding on the teeth of the starter. Check to see if the starter is loose, this is the most common cause of that noise.
