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:

✓Run your palm along tire tread blocks in both directions to detect sawtooth heel-and-toe cupping.
✓Drive at 45–60 mph and lightly steer side-to-side; if humming gets louder loading right side, left bearing is failing.
✓Check rear differential fluid level and magnetic drain plug for excessive metallic paste.
✓Inspect driveshaft center carrier rubber support for dry rot, tearing, or excessive vertical sag.
