Hi,

As the title tells. I have a titan from -06 with constant hard knocking noise folowing the rpm.
after using a stethoscope, i found out that the noise came from the bellhous.
any statics of what the problem can be?

I think that the sound comes from any of these
*Starter
*Loose bolts fore flexplate
*broken flexplate

The sound is like the video is showing, and i know that its not the exhaust

1 vote here for cracked flex plate.
Is there a prize for the first one with the correct guess?? ?

I'll take lose bolt. In any case, next step is box comes out.

Cracked flex plate and or loose bolts are quite common.

If you want to be in the running for the prize (yet to be announced)you have to pick something else- those two are taken! :tongue:

Did u ever find out what it was? My 2012 is starting to very intermittenly make a similar noise, although much quieter than in the video. From best I can tell its coming from where the engine and transmission bolt up.
