If you let go of steering wheel and step on brakes does the wheel vibrate?

I'd say its either warped rotors, power steering malfunction, or possible wheel bearing, although if wheel bearing you should feel/hear a hum which would get louder depending on which way you turn the vehicle.

check the steering arm damper shocky as it may be failing and not providing the proper dampening effect to the steering. Check the wheel bearing adjustment and condition.

The ground should connect to the motor and the motor should connect to the body or chassis. Pour some water on the connection to the engine and the battery terminals. If it is a bad connection things should improve. If you jump start, the donor vehicle needs to be running at a fast idle.
