maybe its your flywheel alittle loose
A vehicle's starter will being making a loud screeching noise if it does not align properly with the flywheel. It slams against the flywheel and grinds against the surface.
Most starting problems will be caused by a faulty relay or solenoid where you will only hear a clicking sound when trying to start the vehicle or a low battery in which case you will hear a buzzing-type rapid clicking noise. Ocassionally a starter does go bad in which case what you are listening for is a whirring noise (bad starter drive) where the starter will turn but not engage the flywheel, or a grinding noise also known as dragging (worn bushings) which is diagnozed by the starter turning very slow. If there is a "clunking" noise while attempting to start the engine, the starter drive gear may be worn and "spinning" on the flywheel without engaging, or the gear and/or flywheel may have damaged teeth. Also, there may be a case of a starter being burnt out in which case you have to remove the starter and hook it up direct to see if it will turn.

the starter is bad.
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.
You need to check your starter or your starter selenoid.
The clicking noise you can hear is the starter solenoid clicking into place. If the starter motor does not turn the engine immediately, it is probably the best place to look. it sounds like the starter motor is faulty.
