Ball Joints and Control Arm Bushings
Symptoms
Clonking over bumps, wandering at speed, uneven tyre wear, steering feels vague.
Cause
Ball joints and bushings wear out. Volvo used pressed-in bushings that can't be replaced separately, so you often have to replace the whole control arm.
Fix
Replace lower control arms (with ball joints and bushings included).
Aftermarket arms are cheaper but often don't last.
Use Meyle HD or OEM Volvo.
You'll need a press or a big hammer and a socket to get the old bushings out if you're replacing them separately.
