SOURCE: 98 lesabre grinding starter

most likely your bendex wheel in the starter is not engaging the flywheel this could be due to a bad solenoid on the starter. chances are it's a bad starter, i would check to make sure all connections to starter are tight and you have atleast 11.5 -12.5 volts of current in the battery. low voltage can cause this problem as well

SOURCE: 1991 Nissan 240SX starter will not turn!

If you've applied 12VDC to the solenoid and it does nothing, not even click, then the solenoid is toast!

SOURCE: grinding when starting, replaced starter one month

The flywheel is worn in that specific area. Engines tend to stop in the same one or two positions, and it is those teeth that get cachunked every time you turn the key. This is ok if the bendix does a good job of threading the gear into the flywheel teeth, but the problem is that now that the teeth are half worn away, the starter attempts to mount its gear to the teeth, but before the gear is fully seated, the contacts in the motor make, the motor starts to turn, and the not-yet-seated gear bounces off of the flywheel teeth. This is what causes the teeth-grinding sound (your teeth grinding in your mouth too!) when you turn the key. . There are two solutions: The first is to, of course, replace the ring gear. . The second is hard to explain, but a good starter rebuild center (if there is such an accessible animal around anymore) will know what I'm talking about: The starter gear must have the lagging edge of each tooth ground so that each tooth will look like a chisel. The "pushing" side of each tooth must be straight and come to the point (and not be beveled). The "non-pushing" lagging side of each starter tooth should have the bevel ground in on that side. This grinding is done easily by a small angle grinder or a Dremel Tool with a cutoff wheel. . This does one thing: It assures that the gear will "spin in" without bouncing. If ground correctly (it's not hard to do), you will get successful starts every time. This is a common fix for Toyota 4-cyl with this horrible all-too-common problem. Good luck.

SOURCE: Starter vs flywheel

It sounds like the starter is not engaging fully and you should change the starter.When you remove the starter check the flywheel\flex plate(Flexplate for automatic trany) for damage.

Grinding starter on my 1988 Ford Bronco II


the sound you hear is the starter grinding against broken teeth on the flywheel, for that to be repaired the flywheel on the vehicle will need to be replaced.

Cranks fine, won't "catch"


From what u describe, I believe u have a starter and possibly a flywheel problem. When u turn the key to start the car, the starter gear engages w/ the flywheel, turning the flywheel, which turns the engine over. It sounds like the teeth of the flywheel and starter are worn, (they should mesh together smoothly) which would make the grinding noise u describe. If this is the case, the flywheel and starter would need to be replaced, and its a labor intensive job, as engine and trans. have to be separated to remove/install the flywheel. The rrrrrrr sound could be the starter gear spinning but not engaging. The starter gear extends on a shaft, then engages the flywheel. It is possible the gear isn't moving forward on the shaft, just spinning w/out engaging, making the rrr sound. So, I would recommend u remove the starter and have it tested (many parts stores will do this for free) and check the teeth on the gear to see if they are worn or broken. U will also be able to see a portion of the flywheel after the starter is removed, and u should check the teeth on it also. Let me know what u find, hopefully it's just a starter problem, and the flywheel is ok.
