Suspension problem
1991 BMW 525i V8 Two Wheel Drive Automatic 150K miles

When I drive the vehicle it starts to shake after hitting 40 mph. I have had the rear wheel bearings replaced, a front caliper replaced (stuck) and all the tires are balanced. I was thinking the control arms need to be replaced (slight movement when I shake). There has been an increase in a 'knocking' noise as well. YOu advice would be helpful, thanks
