How long to replace a flywheel on 2006 300chrysler

This is a pure shot in the dark. I had a similar problem with an Isuzu Bighorn. The flywheel on my car could be replaced in any one of six positions, and it was replaced incorrectly. There is usually one bolt hole that is not quite in the same position as the others, or a dowel which makes it impossible to fit the flywheel incorrectly., but on the Isuzu there is a timing mark on the flywheel, and it can be fitted incorrectly.
If you've fitted a new flywheel, make sure it is for exactly your car - the timing slots which are picked up by the crank angle sensor could be wrong.
Just a shot in the dark . . .

sounds like your starter needs shimmed and/or replaced or you have a flat spot on your flywheel. the sound your hearing is from the starter motor gears not properly aligning with the flywheel gears and quite literally grinding material off of one or the other. if you continue to force it your flywheel will need replaced if not already

flywheel bolted to engine, clutch disk and pressure plate, also has a throw out bearing that should be replaced at the same time.
you don't need to replace the flywheel unless it is cracked though you should have it turned down at a machine shop.

Replace the starter before it ruins the flywheel. You have a worn out drive that applies to the flywheel. Flywheels are very very hard to change, in fact you can change 10 or 15 starters in the same time changing one flywheel

It could be either the flywheel or the starter.
If it's grinding, don't try it again until you've removed and examined the starter and flywheel. If the starter solenoid isn't fully engaging the bendix, it will cause the gear to grind; replace or rebuild the starter if that's the case.
But you should examine the flywheel to see if it is seriously damaged from the problems you've had. Put a mark on the flywheel using a magic marker, then examine the flywheel as you slowly turn the engine by hand. (make certain that the ignition is off when you do that, you don't want anything bad to happen to your hand.) The mark on the flywheel will indicate when you've been able to examine the all of the teeth on the starter ring.

fly wheels are made as a one piece assembly!! so the whole flywheel needs replaced. have a good day!!

May be the Starter bendix not retracting. That would require starter repair or replacement. Repair before flywheel is damaged.

for the starter and flywheel 1400 sounds right they would have to take the tranny out to get to the fly wheel but why do they need to replace the fly wheel did your old starter do a lot of grinding its not to often you have to replace a flywheel unless the starter wrecked it somehow again not to often starters are ment to break before it wrecks the flywheel the flywheel made of harder metel i would get a second opinion on replacing the flywheel

I sit here on this site and help people with their issues all the time, and I do it for free. I've been in the mechanics trade for over 24 years, and I think I have a good idea of what I'm talking about. I don't know it all, and I even need assistance from time to time. The only thing I ask in return for my help, is a good rating from the people I help. Once you replace your solenoid, your issue will be resolved. Yes the fix is that simple. Remember to disconnect the negative cable from the battery before you replace it, so you don't ground anything out.

a buddie and a flywheel wrench. or use an impact wrench
