2021-2025 Ford Bronco Shocks: Standard vs. Sasquatch & Rear Shock Recall
This guide explains the critical differences between Bronco suspension types and covers the major recall affecting Badlands and Sasquatch models.
- A major recall (NHTSA 25V-025) affects the rear Bilstein shocks on 2021-2024 Badlands and Sasquatch models, which can corrode and detach.
- It is critical to distinguish between the standard suspension and the HOSS 2.0 (Bilstein) suspension found on Badlands/Sasquatch models; the parts are not interchangeable.
- When buying used, check for fluid leaks, a straight piston rod, and on Bilstein shocks, inspect the reservoir weld for corrosion.
- Symptoms of failure include excessive bouncing, clunking noises, fluid leaks, and unstable handling during turns or braking.
Symptoms of a Failing Bronco Shock Absorber
A worn or failed shock absorber can make your Bronco feel unstable and difficult to control. Pay attention to these common signs:
- Excessive Bouncing: After hitting a bump or pothole, the vehicle continues to bounce up and down instead of settling quickly. This is the most classic symptom of a worn shock.
- Unstable Handling: The vehicle may feel like it's swaying or rolling excessively during turns and lane changes. You might also notice the front end "diving" forward when you brake hard, or the rear end "squatting" down when you accelerate.
- Clunking or Banging Noises: You may hear a distinct clunking sound coming from a corner of the vehicle when driving over bumps. This can be caused by worn-out internal components or loose mounting hardware.
- Visible Fluid Leaks: Shock absorbers are filled with hydraulic fluid. If a seal fails, you'll see an oily, wet residue covering the body of the shock. A leaking shock has lost its ability to function and must be replaced.
- Uneven Tire Wear: When shocks are bad, the tire can bounce off the pavement, causing a specific type of wear pattern called "cupping" or "scalloping," which looks like hollowed-out spots on the tread. 🎬 Watch: A visual guide to identifying bad shock symptoms.
Known Issues, TSBs, and Recalls for 2021-2025 Bronco Suspension
Major Recall for Rear Shocks (Badlands & Sasquatch Models)
Safety Recall 24S64 / NHTSA 25V-025: Ford issued a major safety recall for approximately 150,000 2021-2024 Ford Bronco models equipped with the Badlands trim or the Sasquatch package. These models use Bilstein shocks with an external reservoir.
The Defect: The rear shock absorbers can experience corrosion between the external reservoir and the main shock body. This can cause the reservoir to separate and fall off the vehicle, creating a road hazard and causing the shock to fail. The issue is particularly prevalent in areas where road salt is used.
Symptoms: Warning signs include a bouncy ride, unusual noises, or fluid leaking near the rear wheels.
The Fix: Ford dealers will inspect the rear shocks. Depending on the condition, they will either replace both rear shocks entirely or apply a specific RTV silicone to the flange and install a newly designed retention clamp as a preventative measure. This repair is performed free of charge.

A few other extremely limited recalls have been issued, such as for a missing nut on a front upper control arm on two vehicles and improperly welded lower control arms on three vehicles. These are not widespread defects but highlight the importance of proper torque and inspection of all suspension components.
Buying a Used 2021-2025 Bronco Shock Absorber: What to Check
Buying a used OEM shock can be a great way to save money, especially since the Bronco is a newer vehicle and used parts often have low mileage. However, careful inspection is key.
1. Verify Compatibility: Standard vs. HOSS
This is the single most important step. The Bronco has several different suspension systems, and the parts are not interchangeable.
- Standard Suspension (HOSS 1.0): Found on Base, Big Bend, and Outer Banks trims (without Sasquatch). These are conventional twin-tube shocks. Part numbers like MB3Z-18125-CP are for this system.
- HOSS 2.0 Suspension (Bilstein): Standard on Badlands and all models with the Sasquatch package. These are upgraded, position-sensitive Bilstein monotube shocks, often with an external reservoir on the rear. They are completely different from the standard shocks.
- 2-Door vs. 4-Door: There are different part numbers for 2-door and 4-door models due to weight differences. Ensure the part you are buying comes from the same body style as your Bronco.
Pro Tip: Always get the VIN from the donor vehicle. This allows you to look up its exact factory configuration (trim, 2-door/4-door, Sasquatch package) to guarantee the shocks are correct for your needs.
2. Physical Inspection
Before purchasing, inspect the used shock absorber carefully:
- Check for Leaks: Look for any oily residue on the shock body. A light film of grime is normal, but wet, dripping oil means the seal has failed.
- Inspect the Rod: The chrome piston rod that extends from the shock body should be perfectly smooth and straight. Any nicks, rust, or bends will tear the seal and cause the shock to fail.
- Examine Mounts and Bushings: Check the rubber bushings in the mounting eyes for cracking, dry rot, or excessive wear. Ensure the mounting points aren't bent or damaged.
- For Bilstein Shocks (HOSS 2.0): Pay extremely close attention to the area where the external reservoir is welded to the main shock body. Look for any signs of deep rust, cracking, or separation, as this is the failure point identified in the recall.
Cost Comparison: New vs. Used Bronco Shocks
Prices can vary significantly based on which suspension system your Bronco has. The standard shocks are much less expensive than the high-performance Bilstein units.
| Part Type | Estimated Cost (Per Pair) | Notes |
|---|---|---|
| New OEM (Standard) | $260 - $425 | This is for the base, non-Bilstein shocks. |
| New OEM (HOSS 2.0 Bilstein) | $1,700 - $1,800+ | These are significantly more expensive. Price is based on repair estimates reflecting high parts cost. |
| New Aftermarket | $200 - $1,500+ | Ranges from basic replacements to high-performance off-road coilover kits. |
| Used OEM | $150 - $400 | A good value, especially for low-mileage take-offs from vehicles getting suspension lifts. |
| Shop Labor (Replacement) | $300 - $800 | For replacement of all four corners. Includes alignment, which is necessary after this job. |
Frequently Asked Questions
What is the difference between the standard Bronco suspension and the Sasquatch suspension?
The standard suspension (HOSS 1.0) uses conventional twin-tube shock absorbers. The Sasquatch package includes the HOSS 2.0 system, which is a major upgrade featuring position-sensitive Bilstein monotube shocks, a higher ride height, and larger 35-inch tires for significantly improved off-road capability. The parts are not interchangeable.
🎬 Watch: A deep dive into Bronco HOSS suspension differences.My Bronco has the Sasquatch package. How do I know if the recall work has been done?
You can check the recall status of any vehicle by entering its VIN on the NHTSA's website or the Ford recall website. A Ford dealership can also look up the vehicle's service history. If you are buying a used shock, there is no way to know for sure, which is why a thorough physical inspection for corrosion at the reservoir weld is critical.
Is it okay to drive with a failing shock absorber?
While you can technically drive the vehicle, it is not recommended. A bad shock absorber compromises your vehicle's handling, stability, and braking performance, increasing the risk of an accident. Continuing to drive can also cause accelerated wear on other suspension components and tires.
Do I need to replace shocks in pairs?
Yes, you should always replace shocks in pairs (both front or both rear) to ensure even handling and stability. Mismatched shocks can cause unpredictable vehicle behavior. Most shops will refuse to replace only one side.
What is the installation difficulty for Bronco shocks?
For a DIY mechanic, replacing the rear shocks is relatively straightforward (Difficulty: 2/5). The front struts are more complex as they are part of a coilover assembly and may require a spring compressor if you are swapping springs. Front replacement is more challenging (Difficulty: 4/5). An alignment is required after replacing front suspension components.
