When I start off in my truck and when I get to 45 MPH the truck will vibrate. I have taken it to the dealer several times and they told me the last time, the truck will just vibrate. Said it is normal. I cannot believe this because I bought the truck with only 1 mile on it and have never abused it. Has anyone out ther had a chevrolet truck that vibrates and you have figured out what was wrong with it?

That's normal AKA I can't fix it and won't admit it LOL.

I would assume they checked all the basics, wheel balance, ujoints, driveshaft balance.

See if you can find out if they checked the balance of the wheels with a radial balancer (road forced balance). This is a type of wheel balancer that applies pressure similiar to the weight bearing of the truck while it is moving. A normal spin balancer will not pick this anomolly up.

Also, while your are moving at the vibrating speeds, will it stop if you take your foot off the aclerator or if you shift it to neutral?

When I let off the gas, the vibration does stop. However, while driving today, the truck felt like it ran over something small in the road. I stopped to check and there was not anything. When leaving work today it did the same and there was nothing there. Could it be the bearings going out?

Disconnect the tcc connector on the transmission, drive it and see if it is still present.
