Broken flex plate?
Hi guys, This is not directly related to 1st gens,but my friend has a 2001 Dodge 1500 gasser that has a strange knock type sound that fades in neutral but gets louder when put in gear. I put a stethoscope on it and it seems to be bottom end towards the back. I don't know much else about the truck but does this sound like a flex plate?...Mark

Cracked flex plates are pretty rare in them. Usually the noise is a very sharp metallic snapping kind of noise where as a rod bearing is more of a duller type knock.
You didn't say how many miles were on it or the condition of the engine or whether it's been maintained well but if it's more of a dull, muffled type knock it's probably a crankshaft thrust or main bearing problem. If the engine has been overheated I would suspect a main bearing problem.

Ah yeah. You would expect a mis-installed transmission to wreck a flex plate. They really aren't supposed to flex much.
It's also pretty tough on TQ (front transmission) bushings.
