2013-2017 Lexus LS460 Inner Fender Liner: A Guide to Damage, Replacement, and Costs
This guide covers the common failure points, replacement costs, and inspection tips for the inner fender liners on all 2013-2017 Lexus LS460 models.
- A damaged or missing inner fender liner exposes critical engine and electrical components to water and debris, risking costly repairs.
- When buying a replacement, a used OEM part is often superior to a new aftermarket one due to better fitment and material quality.
- Inspect used liners carefully for intact mounting holes and cracks before purchasing.
- Replacement is a simple DIY job that requires basic tools and about an hour of time, but it's wise to have new plastic clips on hand as the old ones usually break.
Symptoms of a Bad Inner Fender Liner
Failure of an inner fender liner is usually obvious. Damage typically results from impacts with road debris, bottoming out the suspension, or contact with the tire. Here are the most common symptoms:
- Scraping or Rubbing Noises: A loose or broken liner can make contact with the tire, especially during turns or when going over bumps. This creates a distinct plastic-on-rubber scraping sound.
- Visible Damage: You may see the black plastic liner hanging down from the wheel well, dragging on the ground, or find pieces of it missing entirely. Cracks and holes are common after hitting debris.
- Excessive Debris in Engine Bay: If you notice an unusual amount of dirt, water, or leaves around the engine or on suspension parts, it's a strong sign that the fender liner is compromised and no longer sealing the wheel well properly.
- Broken Mounting Points: The plastic clips and bolts holding the liner in place can become brittle and break, causing the liner to become loose. This is a common point of failure, especially during removal for other services.
Warning: A severely damaged or loose fender liner can detach at high speeds, creating a road hazard for other drivers. It can also get caught in the wheel, potentially damaging the fender, bumper, or suspension components.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Lexus for the inner fender liners on the 2013-2017 LS460. Most issues are related to physical damage from road hazards or aging plastic clips. However, there is a known vehicle theft method where thieves may rip out the driver-side fender liner to access the headlight wiring, which they use to tap into the car's computer network (CAN bus) and program a new key. If you find your liner has been forcibly torn out, it may have been a failed theft attempt.

A used OEM inner fender liner is often an excellent choice, providing the same fit and quality as a new part at a lower cost. However, careful inspection is key.
Why Used OEM is Often Better than New Aftermarket
For a part like a fender liner, precise fitment is critical. Genuine Lexus liners are molded to the exact specifications of the LS460's body and chassis, ensuring there are no gaps for debris to enter or for air to catch and cause noise at speed. Many aftermarket liners, while cheaper, can suffer from poor fitment, thinner materials, and may not include the sound-dampening pads found on the original parts. This can lead to installation frustration and a noisier ride. A quality used OEM part guarantees the original fit and material quality.
Inspection Checklist for a Used Liner:
- Check All Mounting Holes: Carefully inspect every hole where a clip or bolt would pass through. Look for cracks, tears, or elongated holes. A liner with compromised mounting points will not install securely.
- Look for Cracks and Tears: Flex the liner slightly to reveal any hidden cracks. Pay special attention to the edges and the curved areas, which are prone to impact damage.
- Verify Material Integrity: The plastic should still be somewhat flexible. If it feels excessively brittle or chalky, it has likely been degraded by sun and heat and may crack easily during installation or use.
- Confirm Part Number: Look for the genuine Lexus part number molded into the plastic to ensure you are getting an OEM part. The driver's side is 65638-50040 and the passenger's side is 65637-50040 or 65637-50050.
- Sound Dampening Pad: Check if the original white, fibrous sound absorption pad is still attached and in good condition.

Replacement Overview
Replacing an inner fender liner is a straightforward job that is very feasible for a DIY mechanic. The process generally takes 30-60 minutes per side.
- Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels.
- Lift the Vehicle: Loosen the lug nuts on the wheel, then use a jack to lift the corner of the car and support it securely with a jack stand.
- Remove the Wheel: Finish removing the lug nuts and take off the wheel.
- Remove Fasteners: The liner is held in by a series of plastic push-clips and a few 10mm bolts, primarily along the fender lip and underneath the bumper. Use a clip removal tool to pop out the plastic clips.
- Remove the Old Liner: Once all fasteners are out, carefully pull the old liner out of the wheel well. It may require some maneuvering around the suspension components.
- Install the New Liner: Fit the new liner into place, ensuring it tucks behind the fender lip and bumper correctly.
- Install New Fasteners: It is highly recommended to use new plastic clips, as the old ones often break or lose their holding power upon removal. Secure the liner with all clips and bolts.
- Reinstall Wheel and Lower: Put the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer's specification (typically around 76 ft-lbs for the LS460). 🎬 See this step-by-step Lexus fender liner replacement
Pro Tip: Buy a pack of assorted automotive push clips before you start. The original square clips (Lexus part # 90189-06065 or 90189-A0002) are notoriously difficult to remove without breaking.
Frequently Asked Questions (FAQ)
Can I drive my Lexus LS460 with a broken or missing inner fender liner?
You can drive it for short distances, but it is not recommended for long-term use. A missing liner exposes sensitive electronics, wiring harnesses, and the engine bay to damaging water, salt, and debris. A loose liner can also detach and cause an accident or further damage to your vehicle.
Does the inner fender liner need to be painted?
No. Inner fender liners are made of black or dark gray textured plastic and are not painted. They are a functional, non-cosmetic part.
Why is my tire rubbing on the fender liner after installing new wheels?
This usually happens if the new wheels or tires have a different size or offset than the factory specifications. A wider tire or a wheel with a lower offset will position the tire further out, potentially causing it to contact the liner during turns or suspension compression. The 2013-2017 LS460 came with several wheel options, so always verify fitment before purchasing.
Are the fender liners the same for RWD, AWD, and L (long wheelbase) models?
Yes, the front inner fender liners fit all versions of the 2013-2017 Lexus LS460, including standard wheelbase, long wheelbase (L), rear-wheel drive (RWD), and all-wheel drive (AWD) models. However, F-Sport models may have slightly different liners or additional extension pieces, so always verify the part number.
