- Test drove vehicle and confirmed clunk type noise from rear suspension. Inspected vehicle on hoist for any loose or worn parts and found none. Inspected rear brakes and found no obvious issues. Sanded rear brake pads and cleaned rust off brake rotors, but during test drive the issue remained. Rechecked rear suspension and lubricated all rubber bushings, but issue remained. Did some research into manufacturers technical service bulletins regarding rear suspension issues and found one that mentioned possible reflash of rear suspension control module for clunk concern. recommend Cadillac dealership for further evaluation.
