Starter Problem

anyone else notice that the ring teeth look really worn closer to the tips ? im thinking his problem might go away with a new ring gear .
or he could try shimming just one side of the starter to bring the gears closer together since it looks like the teeth are not catching as much as they should , ive had to do that many times on chevys because they had poorly machined belhousings.

GM starters bolt up into the engine block. All GM transmissions have the exact same bolt pattern and do not have provisions for the starter.

If you think about how changing the up/down position looks from the front/back of the engine, it plays with the radius of the ring gear against the position of the starter gear. You shim GM starters if the starter gear is loud and clashing with the ring gear (too close).

The only thing any kind of shim will do on a Chrysler starter will help with thrust alignment, which isn't a problem here.

Check the motor of the starter, the mounting ears of the starter and any other part of the starter to make sure the edges aren't contacting the engine or exhaust. If that all looks ok, pull the starter and check the starter gear housing alignment dowel and cup in the trans.
