Knocking noise in rear when slowing down?

A knocking noise in the rear when slowing down could indicate several issues, such as worn-out suspension components, loose or damaged exhaust parts, or problems with the brake system. It’s essential to inspect the rear suspension, including shock absorbers and bushings, as well as checking for any loose items in the trunk or cargo area. Additionally, examining the brake calipers and rotors for any signs of wear or damage can help pinpoint the source of the noise. If the issue persists, it's advisable to consult a mechanic for a thorough diagnosis.
