Ok so I get this vibration in the steering wheel and gas pedal when I go to 70MPH +. What could be causing it?

Bent rim?
Uneven tire wear?

 

what about the rods, are they okay?

 

70+ is pretty fast, how much vibration? and is it a new problem? When im going 70+ I get some vibration but not tooo much.

 

70-75 MPH isn't that fast. And sometimes I pass at 80 MPH, but not usually.

1. The vibration is enough to make me not get close to 70, but I still do. It feels weird.

2. No it has been going on for awhile.

 

Try swapping the tires/rims from front to back and see if it goes away.
Sounds like a tire is out of balance or a belt broke inside the tire.

 

does your car pull to one side?

I had that and the car was pulling to one side at 70, then discovered it was a cracked wishbone bush, replaced and the pulling has gone but still vibrating a little bit, going to change my wheels around to see what happens, afterall, it did all start after i have changed the wheels around last time

 

I have a 2000 S70 GLT (120,000 mls). Same exact problem, but mine starts @ 65. Gets worse @ 70. Steering wheel vibrates, headrests shake.
Had the entire front end checked, tires/wheels visually checked. Can't find the answer.
