    Hey guys looking for some help troubleshooting some noise complaints...i have been thru 3 starters now and cant figure out my problem. On occasion ( maybe once or twice a week) when i turn the key i get a loud screaching sound when i turn it over...9 times outta 10 the truck starts right up no problem..cant figure it out. I think it may be a broken tooth on whatever it is the starter is engaging into..first 2 times i figured it was a starter and bein under warranty i wanted to eliminate that option. Any input would be appreciated pretty mechanically inclined and would like to fix it..its not a big issue i just dont want it to turn into one and its a little embarrassing and annoying..thanks for the help

    Sounds like missing teeth on the flywheel. Post truck specs, year, tranny, engine etc.

    It does sound like you are missing or damaged teeth on the flywheel. Also who's starter did you install? If you used an inexpensive replacement even under warranty it can do this. Is this the reason why you initially changed out the starter? If not then will the starter warranty cover the damage to the flywheel? I had a Napa premium line starter fail and damage teeth on a manual transmission flywheel ring gear and Napa's warranty covered the whole repair.

    im probably going to tackle this project myself...ive always done most of my repairs on my own..the only work i generally send out to the mechanic is engine and transmission work but because of lack of income im hoping i can accomplish this one on my own...does anybody have any advice or previous expeirience w/ dropping there transmission Im not so worried about removing/installing the fly wheel im more hesitant about the transmission removal/ installation any words of wisdom would be great thanks for the help

    before dropping the tranny, i'd pull the starter, and the dust sheild. roll the engine over with a pry bar in the teeth of the flex plate, and look for worn, damaged, or missing teeth. if you don't see any, then that's not your problem.

    if you can see where the flexplate connects to the ring gear, look for cracks or bends aswell

    this might save you from pulling the tranny.

    you can also measure the depth of the ring gear, compared to the starter mount, then check that the bendix of the starter comes out far enough to fully engage the ring gear. i had that issues on a 79 ford, someone had put the wrong one in, and it would eat the teeth off the ring gear in a month or two
