slight intermitant viberation starts at around 75mph.its not real bad just enough to feel through the steering wheel.Drives fine at any other speed. still does it with new tires. even had tires groundforce balanced.?

 

Been there...... and a lot of times on a new set of tires. Take them back in and get it rebalanced. I had the SAME thing after a new set. Every 7,000 miles I have to get them reblanced.

 

Do you have a long bed or a mega cab? If so most of the time its the two piece driveshaft. You can get a one piece replacment.

 

thanks i will check into that driveshaft and re-blance my tires
