today I noticed weird vibration when warming truck up in park, put in drive didn't notice as much came up stopped at stop sign came to complete stop and could feel vibration again, then accellerate and no vibration, any ideas anyone?

 

Check your harmonic balancer bolts. From there, I'd look at your flexplate. After that... it could be internal.


Was the engine smooth when you felt the vibration? Not missing?

 

engine smooth not missing

 

Yeah, I'd jump underneath and check your harmonic balance bolts. Check for any codes, too.

 

I left work early today to try some of the things suggested, and I pull into my driveway and no vibration when parked. Is it possible that I coould have had snow or ice built up on something that could of caused my truck to vibrate like that?

 

Maybe.

Cold weather does weird stuff to our trucks. Don't sweat it.

 

its probably ice/snow froze underneath ur truck...if u can thaw it out or wash the underbelly with warm water it should stop viberating....i know this becuase i snow plow and my truck does that when we plow when it gets colder than zero degrees

 

Thanks, I'm going to try to get to buddies house this weekend and leave my truck over night and see if it helps. I'll keep you posted, just makes me nervous when something strange happens cause it seems everytime I go to dealer I leave paying $1000 or more to fix something, don't get me wrong I love my truck.

 

Throw some Power Service Diesel Supplement in it!

 

must have been snow or ice build up after thawing out runs like a million bucks
