Ok so I still need some help...

I have a 1990 K2500 350 auto.......................

I have been able so far to fix all the things I have found wrong but there is one I just cant find....

So here is what I have done so far maybe this will lead someone to a idea of what is wrong...If I can remember everything....

1..I swapped the tail gate,rear bumper and trailer hitch..

2..I swapped the front bumper,grill and hood..

3.. I swapped the front diff.,axles,shocks,rotors,hub or wheel bearing.

4.. I swapped rear ends,shocks.

5.. I installed a stereo, 4 speakers and a sub, Then found and fixed a key off drain..The key off drain also had the right rear tail light acting funny but that is fixed now also..

6.. I replaced the starter, fixed the tranny dipstick,fixed leaks in tranny lines..

7..Installed a tranny cooler.

Ok so some time around here I start driving it on short trips to the dump and so on..I find that I have a tearable rattle under the truck..Kinda high pitched log chain dragging on the ground type of sound.. So now we conclude it is coming from the front right or passenger side..I get to looking and...

1..I found the stabilizer end link loose so I replace with a new one.Still got the rattle...

2.. I zip tie anything that looks like it might rattle..Still got the rattle and it is getting worse...

3.. I noticed a shinny line on the top of the idler arm and yup it was loose so I replaced with a new one..Yup you guessed it I still have the rattle..

4.. I had the wheel off and can't find any play in the bearing..

Now if this was a stick I would be thinking throw out bearing so Is there anything in the transfer case or tranny that may sound the same??

Speed does not matter or if in 4 wheel drive or not. The only thing that affects the rattle is if I hit a bump and that leads me back to something loose..

I guess I am hoping for a one in a million hey I had that and all I had to do was??????????????????????

Anyway thanks for all the help thus far............
