Weird 6.0 Vibration NEED HELP

[GrizzlyMan660]

Hey guys I just picked up a 06 F350 Lariat 4in lift with 35's bulletproofed with a SCT tuner. Well i been noticing when im driving no matter what speed if it kicked into OD and around 1500rps i get a slight vibration/humming..... if i put it in tow haul or kicks up a gear it quits. and idea? I also got a jumping when i stop like rotors... I replaced the front 2 and the SOB still does it. This has been my dream truck but now im getting pissed... it only has 110k on it
Thanks
Ron

I would start with the drive line, set the e brake and put it in neutral. Then check the u joints and carrier bearing.

Spool valves on the injectors. Mine did the same thing and when I replaced the injectors I didn't have that problem anymore. Call Jesse warren of warren diesel on Monday and he'll explain it all to you.

Mine had a shudder and vibration when an injector failed also, but it also had a rough idle. Ran like crap, no smoke.

Sent from my phone that somebody didn't help me get.

You should check all the u joints, including the front axle joints, and carrier bearing, as stated before. That sct should read codes.......
