I have a 1995 Nissan Pathfinder with around 130K miles on it. Once I reach a speed of around 60mph, the truck starts to vibrate. The faster I go, the worse it gets. I had the tires rotated and balanced hoping that was the cause. No dice. Anyone have any guesses as to what the problem might be? Thanks
Possible worn suspension components (shocks, cv-joints, tierods, etc).
A tire separation can cause a vibration as well.
You may just need a front-end alignment
…or just a tire balancing
