2022-2025 Ford E-Transit Rear Coil Spring: Diagnosis, Part Numbers, and Replacement
This guide covers the unique rear coil spring suspension on the 2022-2025 Ford E-Transit, including failure symptoms, inspection tips for used parts, and related recalls.
- The 2022-2025 E-Transit uses rear coil springs, not leaf springs like its gas-powered counterparts. The primary OEM part number is NK4Z-5560-D.
- Always replace rear coil springs in pairs to ensure even ride height and stable handling.
- When buying used, thoroughly inspect for cracks, significant rust, and signs of sagging.
- Be aware of the critical safety recall (NHTSA 25V860000) for the rear axle half shaft, which can cause a loss of power or rollaway.
Symptoms of a Failing Rear Coil Spring
Worn or broken coil springs can significantly compromise the E-Transit's ride quality, handling, and load-carrying ability. Because these vans are often used in commercial applications and carry heavy loads, spring failure can be a serious issue. Watch for these common symptoms:
- Visible Sagging: The most obvious sign is a lower ride height in the rear of the van. The vehicle may lean to one side if only one spring has failed, or the entire rear may sit low if both are worn. This can reduce suspension travel and cause the axle to hit the bump stops over bumps, resulting in a harsh ride.
- Clunking or Squeaking Noises: A broken spring can create a clunking or rattling sound as the broken pieces move. Worn spring isolators or metal-on-metal contact can also cause squeaking noises, especially when going over bumps or when the vehicle's weight shifts during acceleration or braking.
- Poor Handling and Instability: Worn springs can cause the vehicle to feel unstable, especially when cornering or changing lanes. You might notice excessive body roll or a swaying motion from the rear of the van. This happens because the springs are no longer able to properly control the vehicle's body movements.
- Uneven Tire Wear: Misalignment caused by a collapsed spring can lead to abnormal and accelerated tire wear patterns.
Related Safety Recall: While not a spring failure, a major safety recall (NHTSA ID: 25V860000, Ford Recall: 25SD9) affects approximately 32,160 E-Transit vans from 2022-2025. The left rear axle half shaft may not be fully engaged, which can cause a sudden loss of power while driving or a vehicle rollaway when parked without the electric parking brake applied. It is critical to have this recall performed by a Ford dealer.
Buying a Used 2022-2025 E-Transit Coil Spring
Since the E-Transit is a relatively new vehicle, finding used parts can be a cost-effective solution. However, careful inspection is crucial, as a faulty used spring offers no benefit. Here’s what to check before buying:
- Verify the Part Number: The primary OEM part number is NK4Z-5560-D. This part supersedes older versions NK4Z-5560-C and NK4Z-5560-A. Ensure the part you are buying matches exactly, as Ford may use different spring rates for different Gross Vehicle Weight Ratings (GVWR).
- Inspect for Cracks: This is the most important check. Carefully examine the entire coil, especially at the top and bottom where it sits in the spring perch. Look for any hairline cracks or fractures. A cracked spring is unsafe and must be discarded.
- Check for Corrosion: Surface rust is common, but deep, pitting rust weakens the spring steel and can lead to failure. Avoid springs with significant flaking or pitting.
- Measure the Free Height: If possible, compare the uninstalled height of the used spring to a new one or its specifications. A used spring that is significantly shorter has likely sagged and lost its ability to support the vehicle's weight.
- Examine the Protective Coating: The original black coating protects the spring from the elements. If large sections are chipped or peeled away, the spring may have been exposed to corrosion-causing moisture and road salt.
Pro Tip: Always replace coil springs in pairs. Replacing only one can result in an uneven ride height, which negatively affects handling, braking, and alignment. A new spring on one side and a worn, sagging spring on the other will make the vehicle unstable.
Cost Comparison for E-Transit Rear Coil Springs
Prices can vary based on supplier and location. The following table provides an estimated cost breakdown for replacing a pair of rear coil springs.
| Part Type | Estimated Cost (Pair) | Notes |
|---|---|---|
| New OEM | $470 - $725 | Purchased from a Ford dealership or online OEM parts retailer. MSRP is around $361 per spring. |
| New Aftermarket | Not Widely Available | As of mid-2026, direct aftermarket replacements for this specific part are not common. |
| Used OEM | $150 - $300 | Price depends heavily on condition and mileage. Requires careful inspection. |
| Shop Labor | $250 - $400 | Represents the cost for a professional technician to install a pair of springs. Based on general suspension labor estimates. |
Replacement Difficulty
- Difficulty Rating: 3/5 (Moderate)
- Estimated Time: 2-3 hours
- DIY Feasible: Yes, for experienced mechanics with proper tools.
Replacing the rear coil springs on an E-Transit requires safely lifting and supporting the vehicle, which is significantly heavy. The basic process involves supporting the frame on jack stands, placing a floor jack under the rear differential to support the axle, disconnecting the rear shock absorbers and any sway bar links, and carefully lowering the axle until the springs are loose and can be removed. Installation is the reverse of removal. This job is not recommended for beginners due to the safety risks associated with working under a heavy vehicle.
Frequently Asked Questions (FAQ)
Why does the E-Transit use rear coil springs instead of leaf springs like other Transits?
The E-Transit's rear-wheel-drive electric motor and axle assembly (Primary Drive Unit) has different packaging requirements than the traditional axle and driveshaft on gasoline models. A coil spring setup provides more flexibility in suspension design and tuning around these components.
Can I drive with a broken or sagging coil spring?
It is not recommended. While the vehicle may be drivable for short distances, a failed spring severely compromises handling, braking, and stability, increasing the risk of an accident. It also puts extra stress on the other suspension components, like the shock absorbers and the opposite spring.
Do I need a wheel alignment after replacing the rear coil springs?
Yes, it is highly recommended. Changing the rear ride height will affect the vehicle's suspension geometry. A four-wheel alignment should be performed after replacement to ensure proper handling and prevent premature tire wear.
Is the rear axle recall (25V860000) related to the coil springs?
No, the recall is for the rear axle half shaft not being properly secured within the drive unit. It is a mechanical issue inside the axle assembly itself and is not caused by the coil springs. However, since the recall involves the rear axle, it is a critical safety repair that all owners should be aware of.
