Buyer's checklist
What to check before buying a used rear bumper cover
- Check the area around the trailer hitch cutout (if any) for stress cracks.
- Confirm whether reflectors and parking sensors are included in the assembly.
- Inspect the step pad area on truck bumpers for cracking from UV exposure.
- Look for paint-match issues: rear bumpers fade differently than steel body panels because they're plastic.
