It seems when im in either fourth or fifth gear and over 50 and onl turning right or steering right i feel a vibration in the floor. For a second i thought maybe ball joints of tie rod's. maybe even bad balance in the front right tire. I recently had my timing belt done and new tires put on wth in the last 5000 miles but just noticed this new vibration. I was wondering if maybe a bad motor mount could have something to do. Im not ase but i got a great vast understanding and ill appriciate any help thanks.

Could be something with power steering. Check weheel balance/alignment...motor mounts tend to go too. Mine are shot and make a vibration around 2200 RPM.

 

When this happened to me my axle fell off. A tight right turn I would feel a vibration from the floor of the car. Not saying that is what your issue is but what you are describing was very similar to my situation.

 

check the motor mounts are tightened up correctly, if they are then i would blame tires.

 

If its like my 02 with over 120k miles....its probably the front control arm bushing...
