Unhappy no one knows

So about a month ago my truck started making a clanking pinging sound at low rpm acceleration and some times at idle. my truck only has 120k on it so it freaked me out( sounds like bottem end problems on a gasser). I took it to my diesel shop, then another, finnaly the dealer, they all told me they cant hear it and they ran it on the comp and nothing came up. Nothing against girls but even my girlfriend who knows nothing about trucks asked me what the noise is. I took it to a tire shop to get my tires rotated and asked him to drive it and listen for the noise. He said that my front gear box is trashed and that is the noise. Its not a lot to fix like $500. It just doesnt sound right I swear its something in the moter/tranny. Maybee im crazy..... ANY HELP???

i would start by checking the oils in the tranny tcase front and rear diff.
if any of them are trashed they should show up in the fluids.
if yous fron diff is bad your fluid will be a silverish color. best to check that after running it a little as the metal settles after sitting.

my truck does the same thing, and has been that way for about 100k or more. I've been told it is the tc as well. Doesn't hurt anything jut really loud and annoying sometimes.

Read this Post in full it cost me having to pull my tranny twice and buying a torqeconvertor that I didnt need. http://www.powerstroke.org/forum/7-3...oise-idle.html It sounds exactly like mine did I thought the bottom end was coming apart but when I would climb under with it running then it sounded like it was in the tranny

If it is the flexplate would you be able to pull the cover off and wiggle the flexplate, becuase I did that and it felt solid?
