Clunking over bumps usually means worn suspension components: sway bar links, ball joints, or strut mounts. Repair runs $150 to $700.
Suspension components connect through rubber bushings and ball joints that wear over time. As they wear, metal-on-metal contact occurs over bumps as parts shift slightly within their mounting points. The most common culprits in order of frequency: sway bar end links (small connectors between the sway bar and suspension, the cheapest fix), ball joints (large pivot points where the steering knuckle meets the control arm), strut mounts (where struts attach to the body), and worn control-arm bushings.
For most causes, yes, for short to medium distances. Sway bar links and bushings can be driven on for weeks without danger. Ball joints are different. A failing ball joint can suddenly release completely, causing the wheel to fold under and producing total loss of steering control. If the clunk is loud, inconsistent, or paired with vehicle shimmy, treat it as urgent. Get an inspection within one to two weeks regardless.
Look under the front end for visibly torn boots or play in the link ball joints. The cheapest fix at $80 to $200.

Document what you find. Hand the notes to the shop when you check in. Technicians charge for time, not for guessing, so anything that narrows the diagnostic search saves you money.
Most shops follow a three-step diagnostic process for symptom-driven complaints: replicate, scan, and inspect. Replicate means the technician drives the vehicle until the symptom appears, confirming it is reproducible. Scan means hooking up an OBD-II scanner to pull stored fault codes and live sensor data. Inspect means putting the vehicle on a lift and checking the components most associated with the symptom and any codes found.
Diagnostic fees in Florida and Georgia run $80 to $150 for the basic process and up to $250 for more involved drivetrain or electrical issues. Many shops apply the diagnostic fee toward the cost of the repair if you authorize the work the same day. Ask whether the shop rolls the diagnostic into the repair before you commit.
