vibration post for DunesRunner08

If anyone can help please...I tried to start a thread, but i couldn't, so here I go with this question.

2006 F250 w 6.0L in it. Mods for power are intake exhaust and programmer. I've had no issues till the past couple days. I am getting a big vibration when the engine is working up to speed. None when I'm in neutral, and it comes and goes, mainly when under load or when i let off the gas and hit it again so its reving up to catch up to get the load (if you get what I'm saying). I have no Idea what the problem is. I tried to return the program to stock and that didn't change it. Has anyone else had this? Can someone help me out?

First it sounds like a drive line vibration when accelerating could be U-joints in the rear drive shaft. I would check that first.

it could be anything from axels to anywhere in the drive train from the tranny or T-case to the drivelines or even rearend. need to do a little checkin and start with the easy to get to like the u joints. then post an update with as much info as possible... what you checked and how you checked it.
why couldn't you start a thread? can we help with that?

its said I didn't have the privledges to do so... I'll keep updating. Dumb question, I can walk out and look at the U-joints now, how can you tell if they are bad? I've done a lot of upgrading in my time, and usually dump vehicles before they break, but this is a company truck and well i'm stuck with it. lol I'm not a maintenance and upkeep guy. Im dumb when it comes to this.

grab the driveshaft near each end and wiggle in all directions it should not move. if you have slack at one end then that end has a bad u joint you should also watch and feel for slack in the yolks

ok. so i crawled under the truck and shook the driveline. the rear u-joint and the carrier bearing were good. the u-joint thats up near the t-case had a little movement and a rattle when i shook it. Is this most likely the problem?

thanks for the help 95
