These sturdy fasteners secure wheel hubs, axles, and driveshafts, preventing wobble, noise, and catastrophic failures during operation. Whether you're repairing a worn-out spindle nut on your daily driver or upgrading for off-road durability, our selection of 15+ products from trusted brands ensures you find the perfect fit for models from Honda, BMW, Toyota, Subaru, and more.
What Are Axle Nuts and Their Importance in Your Vehicle
Axle nuts, also known as spindle nuts or hub nuts, thread onto the end of axle shafts to lock wheel bearings and hubs in place. Found within the Transmission & Drive Train section, they withstand immense torque, vibrations, and road debris. A loose or damaged axle nut can lead to bearing failure, wheel detachment, or uneven tire wear—issues that compromise safety and handling. Regular inspection during tire rotations or brake jobs is key, especially for high-mileage vehicles or those in rugged conditions.
Key Features to Consider When Shopping for Axle Nuts
When selecting axle nuts, prioritize thread size (e.g., M20-1.50, M24-2.0), hex size for wrench compatibility, and material—chrome steel or stainless for corrosion resistance. Look for features like plastic inserts for precise torque retention, staking tabs to prevent loosening, and compatibility with specific makes: Honda's 90305S3VA11 for Accord/CR-V, BMW's RUH100030, or Toyota's 90177-22001. OEM options like Subaru's 902170049 offer exact-fit reliability, while aftermarket kits from brands like MysttooWorldcross provide value packs for fronts or rears.
- Thread Pitch & Diameter: Match your vehicle's specs to avoid cross-threading.
- Nut Style: Hex, slotted, or castellated for cotter pin security.
- Load Rating: Ensure it handles your axle's torque (e.g., trailer axles up to 8K GVWR).
- Kit Options: Pairs for bilateral replacement save time and ensure symmetry.

Common Use Cases and Buying Tips
Axle nuts are essential during wheel bearing swaps, CV axle replacements, or hub assemblies. Front-wheel-drive sedans like Honda Civic/Odyssey often need pairs due to symmetric wear, while 4x4s and trailers demand heavy-duty versions. Always torque to spec (typically 150-300 ft-lbs) using a breaker bar and torque wrench—never impact guns alone, as they can damage threads.
Pro tip: Pair with new axle washers or cotter pins from our Replacement Parts inventory. Verify fitment via your vehicle's year/make/model for seamless installs.
Frequently Asked Questions
What size axle nut does my vehicle need?
Axle nut sizes vary: Honda uses 90305S3VA11 (M24x2.0), Toyota 90177-22001 equivalents, BMW RUH100030. Consult your service manual or use our product filters for exact matches.
Are aftermarket axle nuts as good as OEM?
Quality aftermarket from Beck Arnley or Dorman matches or exceeds OEM in many cases, often at lower cost with similar materials and tolerances.
How do I install an axle nut properly?
Clean threads, apply anti-seize, hand-thread fully, torque to spec, then stake or install cotter pin. Rotate hub to settle bearings before final torquing.
Can I reuse old axle nuts?
Avoid reusing stretched or damaged nuts; always replace during bearing work to prevent comebacks.
Do axle nuts differ for front vs. rear axles?
Yes—fronts handle steering loads, rears propulsion. Subaru nuts like 902170049 fit both in some models; confirm specs.
