Vibrations and pulling to the left at 70mph normal?

Not necessarily

I would think the vibration indicated a tire balance, warped rotor or worn suspension problem. I would also think the pulling was an alignment, brake caliper / pad, or tire defect problem.

It may be that you see these symptoms at 70 because they become severe enough for you to feel the effects.

Most likely simply need a wheel balance (vibration) and an alignment (pulling) but the other possibility is wheel bearing (both). Raise the wheel off the deck and try to move it in and out. You should not feel any movement. Then push the brake pads back away from the disc and spin the wheel. Light scraping will be the brakes but there should be no rumbling or groaning. Movement and or noise means wheel bearings.
