Hello Customer, is the vehicle 2 or 4 wheel drive? Does this go away if you take your foot off of the gas pedal?
Okay. Most of the time this is due to a tire imbalance issue. You need to have all four wheel road force balanced. This gets rid of any disturbance from the tires. if the problem continues then you either have worn out engine mounts or more commonly on this vehicle you have an imbalanced drive shaft. You can remove this and have it balanced by a drive line shop.
