Re: Grinding noises and wont start
Ouch!
As others have noted, check the starter to see if it's loose first, but the low battery starts could have done some serious damage. I have seen the starter gear not fully fit into the flywheel from low power starting which eats off the gears on both the starter 'and' ring gear. If the starter is tight, you need to remove it and inspect the gears on in and on the flywheel. If the flywheel gears are chewed, they will kill a new starter fast, real fast... I find it easiest to pull the engine on a Jeep to fix it rather than pulling the tranny and working from below.... At least the ring gear can be replace, you don't need a whole flywheel if it's chewed up. I had a defective rebuilt starter blow it's nose bushing which ate up my ring gear fast. Sure a new starter was free under warranty, but that 'didn't include pulling the engine or tranny to fix it.

When I bought my current Suburban about seven years ago, it had hammer marks all over the starter. That starter is still in the vehicle, but I haven't had to hit it once since installing a new battery. Before of the "Redneck ASE Diagnosis" which only admits one solution to any given problem.

Re: Grinding noises and wont start
Or take a screwdriver and jump the gear shift/solenoid on the starter.
