When your 2022 Toyota RAV4 makes a clunking noise when going over bumps, loose or worn suspension components are allowing movement that creates impact sounds. Clunking over bumps is one of the most common suspension complaints and has several typical causes.
Sway Bar End Links
Sway bar end links connect the sway bar to the suspension and are among the most common clunk sources. These links have ball joints that wear, creating play that results in clunking when the suspension moves over bumps. End links are relatively inexpensive to replace.
Strut Mounts and Bearings
The strut mount connects the strut to the body and includes a bearing that allows the strut to rotate with steering. Worn strut mounts create clunking over bumps and may also cause noise when turning. The mount's rubber isolator can deteriorate, allowing metal-to-metal contact.
Control Arm Bushings
Rubber bushings in the control arms allow controlled movement while isolating road impacts. Worn or cracked bushings create play that causes clunking. Unlike ball joints, bushings wear gradually and may also cause vague steering feel.
Ball Joints
Ball joints connect the steering knuckle to control arms and allow suspension pivot movement. Worn ball joints develop play that creates clunking and can be dangerous if severe. Ball joints should be inspected for play during any suspension noise diagnosis.
Shock Absorber Issues
While shocks themselves don't typically clunk, their upper mounting hardware can. Loose shock mounts or worn bushings at the mounting points create clunking as the suspension cycles over bumps.
Loose Hardware
Sometimes clunking results simply from loose hardware - a bolt that wasn't properly torqued or has backed out over time. A thorough inspection should check that all suspension fasteners are properly tightened.
