2022-2025 Genesis GV70 Steering Knuckle: Diagnosing Front-End Noises & Compatibility
This guide covers the common failure symptoms, complex part number compatibility, and replacement costs for the 2022-2025 Genesis GV70 steering knuckle assembly.
- Compatibility is extremely complex; you must verify the part number with your VIN, as knuckles differ between Gasoline vs. Electrified, AWD vs. RWD, and Left vs. Right.
- A grinding or humming noise that changes with speed is the most common symptom, indicating a failed wheel bearing within the knuckle assembly.
- New OEM knuckles are very expensive ($1,300+), making a low-mileage used OEM assembly a much more cost-effective solution.
- A wheel alignment is mandatory after replacement to prevent tire damage and ensure safe handling.
Symptoms of a Failing 2022-2025 Genesis GV70 Steering Knuckle
A problem with the steering knuckle assembly often reveals itself through distinct noises and changes in handling. While the knuckle itself is a durable piece of metal, the wheel bearing pressed into it is a common wear item. Many symptoms point to a failing wheel bearing, which is typically replaced as part of the complete knuckle assembly on the GV70.
Noises to Listen For
- Grinding, Humming, or Whirring Noise: This is the most common sign of a bad wheel bearing within the knuckle assembly. The noise is often speed-dependent, becoming louder as you drive faster, and may change or disappear when turning. Some GV70 owners have reported a whirring or humming noise from the front end that is difficult to diagnose but can be related to the wheel bearing.
- Clunking or Popping Sounds: A clunk or pop, especially when turning at low speeds or going over bumps, can indicate excessive play where the ball joints or tie rod connect to the knuckle.
- Clicking When Turning: A clicking sound while turning can sometimes be related to a worn CV joint on AWD models, but it can also indicate excessive play in the wheel bearing.
Steering and Handling Problems
- Vehicle Pulling to One Side: A bent or damaged knuckle will alter the suspension geometry, causing the vehicle to pull to the left or right even after an alignment.
- Vague or Loose Steering: If the steering feels less responsive or wanders, it can be a sign of wear in the knuckle's connection points.
- Vibration in the Steering Wheel: A bad wheel bearing can cause vibrations that you feel through the steering wheel, which may get worse at certain highway speeds.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of mid-2026, there are no official recalls or Technical Service Bulletins (TSBs) issued by Genesis or the NHTSA that specifically address the steering knuckle or wheel bearing assembly for the 2022-2025 GV70.
However, several recalls exist for this vehicle range for other issues, including seat belt pretensioners, fuel pumps, and potential fuel leaks. Additionally, some owners on public forums have discussed front-end noises, with dealers sometimes suspecting wheel hub assemblies as the cause. There is also a TSB related to rear differential noise, which can sometimes be mistaken for a front-end issue.
Buying a Used 2022-2025 GV70 Steering Knuckle Assembly
Due to the high cost of a new OEM knuckle from Genesis, a quality used OEM part is an excellent value. However, careful inspection and verification are critical.
Critical Compatibility Warnings: The GV70 uses several different front knuckles. Ordering the wrong one is a common and expensive mistake. Always verify the exact part number with the seller using your vehicle's VIN before purchasing.
- Gasoline vs. Electrified: The knuckle for the gasoline-powered GV70 is NOT compatible with the Electrified GV70. They use different part numbers.
- AWD vs. RWD: All-Wheel Drive (AWD) models require a knuckle with a splined opening for the front CV axle shaft. Rear-Wheel Drive (RWD) models do not have this opening. The parts are not interchangeable.
- Left vs. Right: Knuckles are specific to the driver's side (Left) and passenger's side (Right). They are not interchangeable. Part numbers often differ by one digit, such as 51710-XXXXX for the left side and 51711-XXXXX for the right.
What to Inspect on a Used Knuckle
- Check for Cracks or Bending: Carefully inspect the entire part for any signs of cracks, especially around the mounting points for the strut, control arms, and brake caliper. A knuckle from a vehicle involved in a collision may have hidden damage.
- Inspect the Wheel Bearing/Hub: The most important check is the condition of the pre-pressed wheel bearing. Hold the knuckle firmly and try to spin the hub. It should rotate smoothly and silently. Any grinding, roughness, or noise means the bearing is bad.
- Check for Play: Try to wiggle the hub flange side-to-side. There should be zero play or movement. Any looseness indicates a worn bearing, and the entire assembly should be rejected.
- Examine Bolt Threads: Check the threaded holes where the brake caliper mounts. If these threads are stripped or damaged, the knuckle is unsafe and unusable.
Is Mileage a Concern?
Yes. The wheel bearing is a wear item. While the knuckle itself can last the life of the vehicle, the bearing will not. A used knuckle from a low-mileage vehicle (under 50,000 miles) is a much safer bet. Bearings on modern vehicles can last 100,000 miles or more, but their lifespan is affected by driving conditions. Given the cost and labor involved, choosing a low-mileage used part is a smart investment.
Why Choose a Used OEM Knuckle?
For the 2022-2025 Genesis GV70, complete aftermarket steering knuckle assemblies are not yet widely available. While some aftermarket companies offer the wheel bearing alone, replacing it requires a hydraulic press and specialized tools. A used OEM knuckle assembly is a complete, pre-assembled unit that ensures perfect fitment and maintains the original suspension geometry and quality engineered by Genesis.
Replacement Information
Replacing a steering knuckle is an advanced repair that requires significant disassembly of the suspension. An alignment is mandatory after the job is complete to prevent uneven tire wear and ensure proper handling.
Related Parts to Replace at the Same Time
- Axle Nut: This is almost always a one-time-use fastener and should be replaced with a new one.
- Ball Joints & Tie Rod Ends: While you have everything apart, inspect the ball joints and tie rod ends for any play or torn rubber boots. It's cost-effective to replace them at the same time if they show signs of wear.
- ABS/Wheel Speed Sensor: This sensor is mounted to the knuckle. It can sometimes be seized and may be damaged during removal. Be prepared to replace it if necessary.
Important Torque Specifications
Warning: Specific torque values for the 2022-2025 Genesis GV70 are not available in publicly accessible documentation. Using incorrect torque specs can lead to premature bearing failure or a catastrophic failure of suspension components. These values must be obtained from an official Genesis factory service manual or a dealership technician.
Key bolts that require precise torque include the axle nut, strut-to-knuckle bolts, ball joint nuts, tie rod end nut, and brake caliper mounting bolts.

Frequently Asked Questions (FAQ)
Can I replace just the wheel bearing instead of the whole knuckle assembly?
Technically, yes, but it is not recommended for most DIY mechanics. The wheel bearing is pressed into the knuckle and requires a heavy-duty hydraulic shop press and specific adapters to remove and install without damaging the new bearing or the knuckle. Buying a complete used knuckle assembly is often faster, safer, and requires fewer specialized tools.
Is the steering knuckle the same for the 2.5T and 3.5T engines?
Part listings suggest there may be differences based on engine and drivetrain options. Because different engines can be paired with different brake packages or drivetrain components (RWD vs. AWD), it is essential to verify the part number with your VIN to ensure you get the correct knuckle for your specific configuration.
Do I need a wheel alignment after replacing a steering knuckle?
Yes, absolutely. The steering knuckle is a central component that determines the position of the wheel. Replacing it will always affect the camber, toe, and caster angles. A full four-wheel alignment is required to prevent rapid tire wear, correct steering pull, and ensure the vehicle is safe to drive.
What is the difference between a steering knuckle and a spindle?
The terms are often used interchangeably, but they technically refer to different designs. A spindle is a shaft onto which the wheel hub and bearings are mounted. A knuckle is a C-shaped component that holds a sealed, bolt-in hub and bearing assembly. Modern vehicles like the GV70 use a steering knuckle design.
