Grinding noises and wont start
Howdy! I'm new to the group, i've had my YJ for about 5 years now and
it's the first time i've ran into anything that has had me stumped. about 4 weeks ago my battery finally crapped out and died. I had driven it with a super low battery for about 2 weeks (i know bad idea) until i came up with the money to replace the bad battery. So i replaced it and everything was fine and dandy until about 3 weeks ago when i went to start my jeep and i got this weird loose grinding noise. Not like something was being torn apart, i guess it would be more of a free spinning chain noise. I was just wondering if anyone had any suggestions about what it might be? The jeep will catch every third of fourth try and start right up but it has me mystified. |

Starter motor ? Check the bolts holding it on first.

Also check the teeth on the flywheel and starter to make sure nothing got broken. -- DougW |

If I remember right these have the kind of Bendix that when the starter spins the centrifugal force causes the gear to extend out into the ring gear on the flywheel or torque converter. When the Bendix starts going bad the gear won't extend properly and it does what you are describing. Although it wouldn't hurt if you make sure all the electrical connections are clean and tight, if the starter is spinning more slowly than it should the same thing can happen. Another possibility is that the ring gear is bad, if you have a habit of trying to start an already running engine that can tear up the ring gear... but that's unlikely. Jeff DeWitt |
