I just replaced the intake gasket/thermostat/radiator cap. Temperature problems solved. Now my truck makes a horrendous metallic grinding noise coming from the starter and fly wheel area. I pulled the starter and testing it by directly hooking it up to the battery. It seems to be working correctly. However, I do see scrape marks on the metal shield around the starter's teeth, but no damage to the actual teeth. What does this mean?
The starter nose bushing is worn and allowing the starter drive to go too far out causing the grinding noise. Replace the starter and make sure any shims that are required be reinstalled unless new starter directions state do not use them. If you would like, a certified technician from YourMechanic can come to your home or office to replace your starter.

Causes include the starter not lining up correctly with the ring gear on the flywheel, missing or damaged gear teeth, or a faulty solenoid. Replacing the starter is most often the right solution. However, if there is damage to the ring gear on the flywheel, the ring gear will need to be replaced.
A starter grinding noise means the starter pinion gear is not lining up correctly with the ring gear on the flywheel or flexplate.
When the starter is not properly aligned, when the starter gear extends out to engage with the flywheel, it may create too much contact with the flywheel. In either case, this is noticeable by a very loud grinding sound.
Usually a grinding noise is due to either a worn starter bendix, worn flywheel, the starter coming loose or it needs to be shimmed. But without knowing the type of vehicle all I can do is give you the possibilities. Good luck and hope this helps.
If you notice a rattle or vibration when driving, and the clutch seems to slip in the higher gears, but you do not smell burning friction material, you`re dual mass flywheel is failing.
Does a Bad Battery Affect Your Starter or Alternator? A bad battery won`t usually harm your starter or alternator, however, since both of those components get their voltage directly from the battery, if the battery is underperforming, both the alternator`s and starter`s performance will be affected as well.
When the starter drive gear is worn out or not engaging properly, it will often produce a grinding noise. This is similar to the one that is heard if you start your engine and then accidentally action the ignition switch again. If the grinding symptom is ignored, it may also result in damage to the engine flywheel.
A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle.
Yes. If the voltage is too low the starter motor won`t spin up fast enough (accelerate) quickly enough to throw the gear along the bendix. On newer cars it is more complicated, but it still seems likely.
Crankshaft grinding consists of removing a minute amount of finished material from the rod and main journals to rebuild the part back to OEM spec. The full 25 step crankshaft remanufacturing process is quite intensive but is critical to complete engine rebuild.
Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically.
Loose flywheel or flexplate bolts make a rattling or knocking sound that changes with engine speed. It`s heard behind the engine, where it mounts to the transmission bellhousing.
Remove the starter from the vehicle and energize it with jumper cables to determine if the starter drive is properly moving the pinion gear into the cranking position. If the starter engages and cranks the engine, then skips and spins freely, there are two likely causes: Misalignment of the replacement starter.
One of the symptoms of a bad starter is a clicking noise when you turn the key or push the start button. However, a starter can die without making any sound at all, or it may announce its impending death with whirring and grinding noise—so listen up!
When you attempt to start the vehicle, is there a clicking sound, but it won`t turn over? That may be a good sign. If a jump gets the car running, but won`t turn over again once it`s shut off, a dead battery is likely the cause.
Typically, a new starter will make noise when it`s positioned too close to the ring gear on the flexplate or flywheel. Installing thin, steel shims between the block and starter is the method to eliminate the noise. Another problem that may cause starter noise is an out-of-round flexplate.
If one or more of the flywheel`s teeth are damaged or broken, then the wheel can`t engage with the starter motor. You might need to try a few times to get your car to start, or it might not start at all.
A loose starter can knock teeth off the flywheel. A starter bendix can wear the teeth off the flywheel or make it doesn`t always engage properly. If it doesn`t disengage when the engine is running it can again ruin the teeth. yes a starter can damage the flywheel.
