2013 Jeep Compass - Control Arm Bushing Noise?

Noise from under the rear drivers side suspension. Did not know what it was at first. Had brakes. shocks and struts all replaced. Still this awful grinding noise. Had 3 mechanics look at it also. Everyone says the same thing. Noise is coming from the suspension control arm bushing. However not one person can fix it. I am running out of options. I am on a fixed income and can not afford much more. I cant sell it cuz nobody in their right mind would want to buy it. Can you help?

That seems definitive

Why not?
