- Loose or worn suspension components: Check the condition of the suspension components such as control arms, ball joints, tie rods, and sway bar links. Worn or loose components can cause knocking or thunking sounds over bumps.
- Strut or shock absorber issues: Worn or damaged struts or shock absorbers can lead to a thumping noise when the suspension compresses.
- Sway bar issues: A loose or damaged sway bar or its linkage can create a thunking noise when the suspension moves.
- Loose or worn wheel bearing: A bad wheel bearing can cause a variety of sounds including a thumping noise when the wheel is turned or going over bumps.
- Damaged tire: A damaged or deformed tire can cause thumping or bumping sounds while driving.
- Loose lug nuts: Ensure that the lug nuts on your wheels are properly tightened. Loose lug nuts can cause knocking or thumping sounds over bumps.
To determine the exact source of the thunking noise, it is recommended to have the vehicle inspected by a qualified mechanic or technician who can diagnose the problem and perform the necessary repairs.
