The fender liner, also known as the splash shield or inner fender, is an essential component of the Toyota Highlander's wheel well assembly. It acts as a protective barrier between the wheel and the engine compartment, shielding vital parts from dirt, debris, water, and other road hazards encountered during daily driving.
A properly functioning fender liner safeguards the engine bay and undercarriage by preventing contaminants from causing damage or corrosion. It helps maintain the overall integrity of the vehicle by reducing the risk of mechanical failures due to exposure. Additionally, the fender liner contributes to the vehicle's aerodynamics and fuel efficiency by managing airflow around the wheel wells.
Over time, fender liners can experience wear and tear due to various factors:
Physical Damage: Impacts from road debris, potholes, or minor collisions can crack or puncture the fender liner.
Wear and Tear: Continuous exposure to harsh weather conditions like rain, snow, and extreme temperatures can weaken the material.
Loose Attachments: Fasteners and clips may become loose or break, causing the liner to hang or drag.
Symptoms indicating a damaged or failing fender liner include:
- Unusual noises such as flapping or scraping sounds from the wheel area
- Visible cracks, holes, or missing pieces in the liner
- Accumulation of dirt or debris in the engine compartment
- Water intrusion under the hood after driving in wet conditions

Regular Inspection: Periodically check the condition of the fender liner during routine maintenance or when cleaning the vehicle.
Secure Fasteners: Ensure all clips and screws are intact and tightened to keep the liner firmly in place.
Proper Fitment: When replacing the fender liner, choose one designed specifically for the Toyota Highlander to guarantee a precise fit.
Installation Steps:
- Safely lift and support the vehicle if necessary.
- Remove the wheel for better access to the wheel well.
- Detach the damaged fender liner by removing all fasteners.
- Align the new liner correctly within the wheel well.
- Reinstall all clips and screws securely.
Professional Assistance: If unsure about the installation process, consult a certified mechanic to ensure the job is done correctly.
