hello all just a quick question if anyone can help me. i have a vibration in my 2000 chevy silverado 4 wheel drive 1500 when i have my foot on the gas it vibrates like crazy but soon as i take my foot off the gas it stops vibrating???? anyone help me please?

 

it could be a few things bent rim wheel weght nocked off. drive shaft could be any rotating part of the drive train. hard to tell these things without beening in the truck. hope that little bit helps.

 

if this helps any the vibration happends the most from 55 too 70 thats when it does it the most i changed my universal joints they where a lil bad and that fixed the clunk that i had had but the vibration is still there is there any chance that it could be ny transmission ? it dont have a problem shifting or anything but i am lost ???

 

I had a similar vibration on my truck when I changed out the u-joints. What caused mine was the drive shaft was 180 degrees out but this is on a long box which has a two piece drive shaft after I flipped it back the vibration stopped. You might want to try and rotate the drive shaft 180 and see if that helps.
