Diagnosis and Repair
1. Visually inspect the right rear interior panel: Check for loose or broken fasteners, damaged or worn-out door check straps, or a failed latch mechanism.
- For loose or broken fasteners, use a screwdriver to tighten them or replace them as necessary.
- For damaged or worn-out door check straps, the only viable option is to replace the strap with a new one.
- If you find that the latch mechanism, you should either replace it with a new one or lubricate the old mechanism and hope for the best.
2. Check for loose spare tire or jack: Ensure the spare tire or jack is properly secured in place. Tighten any loose bolts or screws as necessary.
3. Check the seatbelt: Ensure the seatbelt assembly is properly bolted or screwed to the quarter panel. Inspect for loose bolts or screws and tighten as needed.
4. Check the shock or strut: Knocking noises can also be caused by a bad shock or strut. Take your vehicle to a mechanic to have the shock or strut replaced.
