Step-by-Step DIY Diagnostic Checklist
Perform these physical checks safely before visiting an auto shop to isolate whether the issue is simple external hardware or internal mechanical wear:
- ✓Perform a slow full-lock turn in an empty parking lot; rhythmic clicking on tight turns confirms outer CV joint failure.
- ✓Look behind front wheels for torn accordion CV rubber boots and flung black axle grease.
- ✓Listen behind dashboard when changing temperature or air recirculation; rapid clicking confirms stripped blend door gear.
- ✓Check brake caliper guide pins and anti-rattle clips for missing hardware or loose fit.
