2013-2014 Honda Fit EV Rear Lower Control Arm: A Guide to the EV-Specific Suspension
This guide covers the unique multi-link rear suspension lower control arm found only on the 2013-2014 Honda Fit EV, including failure symptoms and replacement costs.
- This part is ONLY for the 2013-2014 Honda Fit EV. It will not fit standard gasoline models due to a different rear suspension design.
- Failure is typically indicated by clunking noises from the rear over bumps and a feeling of instability at speed.
- No aftermarket options exist; a used OEM part is a cost-effective alternative to a new dealer part.
- A four-wheel alignment is mandatory after replacement to prevent unsafe handling and rapid tire wear.
Compatibility Warning: Honda Fit EV Models Only
Critical Fitment Information: This rear lower control arm fits ONLY the 2013-2014 Honda Fit EV (Electric Vehicle). It is not compatible with any standard gasoline-powered Honda Fit models from any year. Standard Fits use a completely different rear suspension design called a torsion beam or twist-beam axle, which does not have this part. Attempting to install this on a non-EV model will fail as the mounting points and entire suspension architecture are different.
Symptoms of a Failing Rear Lower Control Arm
A failing rear lower control arm is most often due to worn-out rubber bushings or, less commonly, damage from an impact. The symptoms can range from subtle noises to significant handling problems.
- Clunking or Knocking Noises: This is the most common symptom. You may hear a distinct clunking, knocking, or banging sound from the rear of the car, especially when driving over bumps, potholes, or uneven pavement. This sound is caused by excess play in the worn bushings, allowing metal components to make contact.
- Unstable or Wandering Rear End: The vehicle may feel loose or unstable from the rear, particularly at highway speeds. You might feel the car subtly shifting or 'steering' from the back, requiring more steering corrections to keep it straight. This indicates the arm is no longer holding the wheel assembly securely in place.
- Uneven Tire Wear: A worn control arm can throw the rear wheel alignment out of specification. Inspect your rear tires for accelerated wear on the inner or outer edges. This is a classic sign of an alignment issue caused by a failing suspension component.
- Excessive Vibrations: While more common with front control arm issues, a badly worn rear arm can also transmit vibrations into the cabin, which may be felt in the seats or floor.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no known Technical Service Bulletins (TSBs) or safety recalls issued by Honda or the National Highway Traffic Safety Administration (NHTSA) for the rear lower control arms on the 2013-2014 Honda Fit EV. All published recalls for this vehicle relate to the Takata airbag inflators. The suspension components are considered robust, with failures typically resulting from normal wear and tear on the bushings over time and mileage.
Pro Tip: Due to the low production numbers of the Fit EV (only about 1,100 units were produced), widespread 'common issues' are not well-documented. Failures of this part are typically isolated incidents rather than a systemic problem.
Buying a Used Rear Lower Control Arm
Given the high cost of a new OEM part and the lack of aftermarket options, a used OEM control arm is an excellent value for this repair. Since the arm itself is a solid piece of metal, failure is almost always in the rubber bushings. Here’s what to inspect:
- Inspect the Bushings: Check the rubber bushings at both mounting points. Look for any signs of cracking, tearing, rotting, or separation from the metal sleeve. The rubber should be firm and intact. Avoid any arm with visibly damaged bushings.
- Check for Bends or Cracks: Visually inspect the entire length of the arm. Ensure it is straight and free of any bends, dents, or cracks. Place it on a flat surface to easily spot any warping. An arm that has been damaged in a collision is unsafe to use.
- Verify Part Numbers: Confirm you are buying the correct part for the correct side. The left (driver's side) and right (passenger's side) arms are not interchangeable.
- Mileage vs. Condition: For a structural part like a control arm, physical condition is more important than mileage. A low-mileage part from a vehicle in a northern, salty climate may have more corrosion and bushing wear than a higher-mileage part from a dry, southern climate. Prioritize the visual inspection over the mileage number.
Replacement Overview and Costs
Replacing a rear lower control arm is a feasible DIY project for someone with mechanical experience and the right tools. However, it requires safely lifting and supporting the vehicle, and an alignment is mandatory after the job is complete.
| Item | Estimated Cost |
|---|---|
| New OEM Part | $400 - $700 per side |
| New Aftermarket Part | Not Available |
| Used OEM Part | $75 - $200 per side |
| Shop Labor | $200 - $400 per side |
| Wheel Alignment | $100 - $150 (Required) |
| Total Professional Repair (New OEM) | $700 - $1250 per side |
| Total Professional Repair (Used OEM) | $375 - $750 per side |
Special Procedures & Torque Specs
While specific torque specs for the Fit EV's rear control arm bolts were not found in general documentation, a critical procedure applies to all control arm replacements:
Important: The main pivot bolts for the control arm bushings must only be torqued to their final specification when the suspension is at normal ride height. This means the full weight of the vehicle should be compressing the suspension. You can achieve this by using a jack to lift the wheel hub to a normal height before tightening, or by tightening the bolts after the car is back on the ground. Tightening the bolts while the suspension is hanging down will preload the bushings, causing them to tear and fail prematurely.
General torque specs for similar Honda applications include:
- Wheel Lug Nuts: 80 lb-ft
Frequently Asked Questions (FAQ)
Will this control arm fit my regular 2013-2014 gas-powered Honda Fit?
No, absolutely not. This part is exclusively for the Honda Fit EV, which has an independent multi-link rear suspension. The gasoline-powered Fit uses a torsion beam rear axle and does not have this component.
Can I just replace the bushings instead of the whole arm?
While technically possible if replacement bushings are available, it is often not practical. Removing the old bushings and pressing in new ones requires a hydraulic press and specialized tools. The labor cost for this process at a shop can often meet or exceed the cost of a complete used control arm assembly, which is much faster to install.
Do I need a wheel alignment after replacing this part?
Yes. Replacing a lower control arm will always affect the vehicle's wheel alignment. A four-wheel alignment is required after replacement to ensure proper handling, prevent pulling, and avoid premature tire wear.
What is the difference between the part numbers?
The part numbers distinguish between the left and right sides of the vehicle and may also indicate updated versions. Based on dealer catalogs, 52371-TX9-A02 is the Left Rear (Driver's Side) arm. It likely supersedes part number 52371-TX9-A01. The part number 52350-TF8-A00 is understood to be for the Right Rear (Passenger's Side) arm, following Honda's numbering patterns.
