You have Toyota Avalon 98 xls you are not sure what cause little noise around the right side rear end when your car run over bumpy road Technician told shock fine make noise?

There are a few possible causes for the little noise around the right side rear end of your Toyota Avalon 98 XLS when it runs over bumpy roads, despite the shocks being fine. Here are some things to consider:

1. Sway Bar Links: The sway bar links connect the sway bar to the control arms and help stabilize the vehicle. If the sway bar links are worn or loose, they can cause a knocking or clunking noise when the vehicle goes over bumps.

2. Control Arm Bushings: The control arm bushings are rubber mounts that connect the control arms to the frame of the vehicle. If the control arm bushings are worn or cracked, they can cause a squeaking or groaning noise when the vehicle goes over bumps.

3. Strut Mount: The strut mount is a bearing that allows the strut to rotate when the vehicle turns. If the strut mount is worn or damaged, it can cause a clunking or popping noise when the vehicle goes over bumps.

4. Exhaust System: The exhaust system can also rattle or vibrate against other components of the vehicle, causing a noise when driving over bumps. Check for any loose or damaged exhaust hangers or brackets.

It is recommended that you have the vehicle inspected by a qualified mechanic to determine the exact source of the noise and have it repaired accordingly.
