Question.. didn't you wait at least 500mi for a little break in period? And I'd say it's the drive shaft. I had the same thing. I bought from Belltech Drive shaft spacer kit to help steady the shake.

I don't have a 2pc driveshaft, therefore there is nothing to space. The part you are referring to is designed for 2-piece driveshafts.
I am thinking its the pinion angle as well. Gotta get her over to the shop and have it checked out!

i had the same exact problem with my truck and it was the driveshaft.i have the gm 4.10 gears also changned form 3.23s.i blew the driveshaft in half at about 87ish,scared the gell out of me and it was right after i installed the gears because before it never did that.i am going to a 2 piece driveshaft soon.a few of my friends with dropped crew cabs had already changed thiers out and it dont do it no more.from what they are saying is to use a driveshaft from a extended cab truck.you just have to weld in the support in the center.the one piece is weak and very thin alluminum and is packed with foam inside.i still have it saved for people who dont believe me,but yeah the driveshaft is the problem.

crew cabs only come w/ a one piece drive shaft.

this was an old post, but my 05 crew cab makes that growl/vibrate at 90-100 with the 4.10's i had and now the 4.56s, 3.73s it was fine. i have taken well to 130mph, just at the 90-100 its there then smooths right out. what kind of built driveshaft should i look for , or is going to the 2 piece a better option. thanks

a lil update. The guy who bought my truck took the 4.10s out and put the stock 3.23s back in with the true trac and the noise went away. Looks like the 4.10s were bad.
