Infiniti qx4 shaking

I own an Infiniti qx4. 2001. When I drive above 65 mph the steering wheel is shaking, and when I need to veer left or right the bouncing is worse. I changed my tire rods, front end alighment, high speed balance, and had my aluminum wheels tested and fixed for any bumps and dents. What else could be wrong and I can do to fix this problem. Thanks

Replace the front struts.

These Cars Have A Steering Rack Sliding Force Adjustment, But Should Be Checked By Carefully Following Procedures Before Considering This.

Please confirm that the tires / wheels were balanced on a “road force” type balancer that simulates an actual road test. Were the tires checked for radial and lateral run-out ?
