I have this shaking problem when you accelerate between 40mph to 70mph going up an incline. Going down hill it does not shake that much. We have replace the rims and tires, on the recommendation of our machenic, but it still happens. What could the problem be?
The vibrations may not be from the drivetrain or suspension but from a miss in the engine.
Poor plugs/wires/coil pack(s) or perhaps even timing.
