Starter or Solenoid

When turning the ignition, Jeep makes a loud grinding/screetching noise... Eventually turns over and once running is great...

Anyone have a solid idea if it's my solenoid or starter going out? OR is it something else altogether???

Thanks for any help...

Matt

A loose starter can act like that too. So can dirty connections on the starter power cable from the solenoid down. If not enough power get down there, it doesn't kick the gear out hard enough.

the sound is pretty hideous...

how does a starter become "loose"? If the starter isn't getting enough power, doesn't that point to the solenoid?

I had a bad spot in my flywheel on my 2A years ago. Every once in a while, it would come up & the starter would grind against it. Hope it's a simpler problem than that.

#hit happens. Go give it a shake to see.

Yes, no, maybe. The fender solenoid/relay unit is a cheap part that does wear out over time. It is also 'very' prone to getting bad connections under the cable ends where you can't see it so a good clean sure won't hurt. While cleaning the starter cable, cleaning the starter end also is a good idea.

Sometimes starters fill up with mud and then don't kick like they should. A dismantle and good clean with WD40 and regrease can sometimes do them wonders. If you find worn brushes, then would be the time to replace them, they are cheap.

I had a brand new remanned starter blow out it's nose bushing, Guess they forgot to change that part and it killed my flywheel's ring gear within 2 weeks.

I really wouldn't let it grind for too long.....

Yeah and once your ring gears gets screwed up, it will keep messing up the gears on your new starter also...

Thanks to all for the thoughts...

Mike Romain... Special thanks to you. the damn thing was essentially hanging by one bolt. The other one had snapped off.

New bolts installed and all is well

That great grinding noise is your starter eating the teeth off your ring gear...

Really good idea to go get a starter that will actually engage the teeth of the ring gear before you need to replace the ring gear & flex-plate/flywheel!
