Possible bad problem?!?

I just got the fuel pump changed and all the lines replaced and my truck. Now its making a strange noise. The truck runs fine and has lost no power. At idle it makes a bumping noise that feels like something is hitting the floor pan. It also make the same noise but worse when I shut the truck off. I checked the downpipe and it isnt touching the firewall. I thought it may be a bad engine mount or tranny mount but they look fine and I don't know how I can check them. I've also heard of people having problems with the 2 piece flywheel. What are the symptoms of this? Has anyone had a similar problem or know what it could possibly be? Thanks in advance for any help.

Jason

It very well could be the flywheel. You may want to check everything over good before you decide to remove the tranny to check the flywheel.

It only does this when I stop and the truck is idleing. When Im slowing down to stop or taking off it doesnt have any vibration or make any noises. The main thing that bothers me is how it shakes when I shut the truck off. Could it have anything to do with the vaccum pump I just replaced?

maybe your downpipe rubbing on the trans crossmember?
could be the dual mass flywheel and clutch missing some pieces.causing an imbalance.
