Just to update this thread.
I ended up sending my lens to Tamron. I was charged $159 for everything including the signature confirmation. It was well worth it!
Here is what they did:

LOOSE OR MISSING PARTS.

2 TURNAROUND TIME APPROX 3 BUSINESS DAYS 800-827-8880
Sent it March 23 and I got it April 2nd.
It was bought in the grey market (ebay) and It was not warrantied. So i had to pay. But I am glad I didnt just jump the gun and bought a new one. It is good as new now!
Hope anyone with this problem gets to solve theirs!
