Hey Guys, my other project, (Dodge Colt) is getting some new parts. Does this flywheel look like it needs turning? It's very smooth, no ridges. Those lines are not grooves. 56 K on it. Some rust only from sitting. Your thoughts?

Thanks! Toddhttp://www.ultimatesubaru.org/forum/picture.php?albumid=125&pictureid=2361

Yes, it needs to be turned to avoid shudder.

I agree - it could be "wavy" and the smooth surface will not seat in a new disc very well. In the same way that roughing up a rotor when you replace brake pads it's always a good idea to mill a flywheel so you know for a fact it's completely flat and will seat the disc in properly. The $35 cost is definitely worth it considering what's at stake (pulling the engine or tranny back out :mad:).
