2013-2018 Toyota Avalon Center Pillar: A Collision Repair and Replacement Guide
This guide covers the essential information for replacing a damaged center pillar on a 2013-2018 Toyota Avalon, focusing on sourcing a used part and the critical professional installation process.
- Center pillar replacement is a structural repair required only after a significant side-impact collision.
- This is not a DIY job. Professional installation with specialized welding equipment is mandatory for the vehicle's safety.
- When buying a used pillar, ensure the 'cut' is long enough and includes the 'dogleg' section, as specified by your body shop.
- A critical airbag ECU recall (20V024000) affects this vehicle generation; ensure it has been addressed, as it impacts side-impact safety systems.
Why Is the Center Pillar Replaced?
The center pillar is a core part of the vehicle's safety cage. Unlike mechanical parts that wear out over time, a center pillar is almost exclusively replaced due to significant damage from a side-impact collision. It is not a maintenance item and does not 'fail' on its own. If your center pillar is damaged, it means the vehicle's structural integrity has been compromised and repair is essential for safety.
Symptoms of a Damaged Center Pillar
The signs of a damaged B-pillar are typically obvious after an accident, but even minor-looking damage can indicate a serious problem.
- Visible Damage: The most obvious symptom is a bent, crushed, or torn pillar resulting from a direct impact. Any visible deformation means the part needs to be professionally inspected and likely replaced.
- Poor Door Alignment: A bent pillar will prevent the front or rear doors from closing, latching, or sealing properly. You may see uneven gaps between the door and the body.
- Wind and Water Leaks: If the door isn't sealing correctly against the pillar, you will likely experience excessive wind noise at speed or find water leaking into the cabin during rain.
- Body Creaks and Noises: A compromised pillar can reduce the overall stiffness of the car's body, leading to creaking or popping sounds as the chassis flexes while driving over bumps or turning.
Warning: Never attempt to straighten a damaged center pillar. These parts are made of high-strength steel designed to deform in a specific way during a crash. Once bent, the metal's strength is compromised, and it cannot be safely repaired. It must be replaced.
Buying a Used 2013-2018 Avalon Center Pillar
For a structural part like this, your options are typically a brand new OEM part from a Toyota dealer or a used OEM part from a recycled vehicle. Aftermarket structural pillars are generally not available due to the safety-critical nature of the part. A used OEM pillar is a cost-effective and safe option, provided you know what to look for.
Inspection Checklist for a Used Pillar:
- Verify the Cut: This part is cut from a donor vehicle. You are buying a 'body cut'. Before purchasing, talk to your body shop technician. They will have specific requirements for how much material they need above and below the damaged area to perform a proper repair according to Toyota's sectioning procedures. Ensure the seller provides a 'standard cut' or a 'long cut' that includes plenty of extra material for the technician to work with.
- The 'Dogleg' Section: Pay close attention to the lower part of the pillar where it joins the rocker panel (the beam running under the doors). This L-shaped section is often called the 'dogleg'. A used pillar that includes a significant portion of the rocker panel is often preferred for a stronger, more seamless repair.
- Inspect for Hidden Damage: Carefully examine the entire used part for any signs of kinking, bending, or stress marks. It must be perfectly straight. Also, check for any rust, especially on the inside and along the bottom where moisture can collect.
- Confirm the Correct Side: Part numbers for the left (Driver Side) and right (Passenger Side) are different. Double-check that you are ordering the correct side for your repair.
Known Issues, Recalls, and Service Bulletins
There are no known recalls or Technical Service Bulletins (TSBs) for the steel center pillar structure itself. However, there is a critical safety recall involving components located in this area.
Recall 20V024000 (NHTSA ID): Affects 2012-2018 Toyota Avalons. The airbag electronic control unit (ECU) can malfunction during certain crashes, which may prevent the airbags and seatbelt pretensioners from deploying. This is a serious safety risk. The fix involves a dealer installing a noise filter on the airbag wire harness or performing a software update. If your vehicle is undergoing pillar replacement, it is an ideal time to ensure this recall has been completed.
Replacement: A Job for Professionals Only
Replacing a center pillar is a complex structural repair that must be performed by a qualified auto body technician. It is not a DIY project.
Warning: Improper replacement of a center pillar will severely compromise your vehicle's safety in a future collision. The procedure requires specialized equipment and adherence to manufacturer-approved sectioning procedures.
The process involves:
- Precisely cutting out the damaged pillar section.
- Drilling out dozens of factory spot welds holding the inner and outer pillar structures.
- Preparing the joining surfaces on both the vehicle and the replacement part, including applying special weld-thru primer.
- Test-fitting and precisely measuring the new pillar's position.
- Welding the new pillar into place using a combination of resistance spot welds and MIG welds to replicate factory strength.
- Applying seam sealer, corrosion protection, and refinishing the area.
Cost of Replacement
The cost is significant due to the high amount of skilled labor required. The part itself is only a fraction of the total cost.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Pillar Assembly (Inner & Outer) | $500 - $750 per side |
| Used OEM Pillar Assembly (Cut Section) | $250 - $450 per side |
| New Aftermarket | Not typically available |
| Shop Labor (Structural Repair & Refinishing) | $1,000 - $2,700 |
Part Numbers
These are the primary structural components for the 2013-2018 Avalon center pillar. Always confirm the exact part number with a dealer using your vehicle's VIN before ordering.
| Component | Right (Passenger Side) | Left (Driver Side) |
|---|---|---|
| Outer Pillar & Rocker Panel | 61311-07030 | 61312-07030 |
| Inner Pillar | 61307-07010 | 61308-07010 |
| Upper Reinforcement | 61303-07010 | 61304-07010 |
Frequently Asked Questions (FAQ)
Can I just have my bent center pillar straightened?
No. The high-strength steel used in modern pillars is designed to crush in a very specific way to absorb impact energy. Once it has been deformed, its structural integrity is lost and it cannot be safely repaired. It must be replaced following manufacturer procedures.
Is a used center pillar from a salvage yard safe?
Yes, provided it is an undamaged OEM part that has been correctly installed by a professional body shop. A straight, rust-free OEM pillar from a donor car is identical to the original part on your vehicle. The skill of the installer is the most critical factor for safety.
What is the 'dogleg' and why is it important?
The 'dogleg' is the common term for the lower part of the center pillar that curves and connects to the rocker panel (the structural beam below the doors). When buying a used pillar, getting a cut that includes this section and part of the rocker panel gives the repair technician more original material to work with, often resulting in a stronger and more accurate repair.
Does the replacement pillar come with the seat belt or airbag?
No. A new or used structural pillar is just the bare steel structure. All other components, such as the side curtain airbag, seat belt mechanism, wiring, and interior trim panels, must be transferred from your old pillar or purchased separately.
