Required Quantity
Two nuts are required per car for the applicable front wheel bearing arrangement. Sold each.

What Is This Part?
This is the threaded adjusting and locking nut used at the outer end of the front wheel spindle. It works with the thrust washer and wheel bearings to establish the bearing adjustment. Once that adjustment has been set, the clamping bolt secures the nut in position. The nut and its bolt therefore have separate roles: the nut establishes the setting, while the bolt locks it. 

What Does This Part Do?

• Adjusts the bearing: The nut moves along the spindle thread to establish the front wheel bearing setting. 
• Works with the thrust washer: The washer forms part of the bearing adjustment arrangement and is checked during adjustment. 
• Locks the setting: Tightening the clamping bolt holds the nut in its adjusted position. 

Why Replace This Part?
Replacement is appropriate if inspection reveals damaged threads, cracking, substantial corrosion or damage around the clamping bolt connection. These defects can prevent the nut from moving correctly on the spindle or holding its adjusted position. Damage caused during earlier removal or overtightening should also be assessed before refitting.

Wheel bearing servicing is a useful opportunity to inspect the nut, bolt, thrust washer and spindle threads together. Bearing play or noise does not identify the nut as the cause by itself; the bearings and the rest of the assembly need checking before deciding which components to replace.

When to Replace This Part?

• Damaged threads: The nut binds, cross-threads or will not engage correctly with an undamaged spindle.
• Cracks or distortion: The nut body or clamping area is visibly damaged.
• Defective bolt connection: The clamping bolt or its threaded connection is damaged and cannot secure the nut correctly.
• Significant corrosion: Deterioration affects the threads, seating surfaces or clamping area.
• Adjustment will not hold: Inspection confirms a fault with the nut or its locking connection after checking the complete bearing assembly.

Where Is This Part Fitted?
Location: At the outer end of the front wheel spindle, beneath the grease cap, alongside the thrust washer and outer wheel bearing. The grease cap is removed to access the nut for bearing adjustment and inspection. ()

Technical Details

FAQs

• Can I reuse the existing nut? Inspect its threads, body and clamping connection, then follow the workshop instructions for the specific vehicle. Replace it if damaged or if the applicable instructions require renewal.
• Is this tightened like a conventional driveshaft hub nut? Follow the vehicle-specific front wheel bearing adjustment procedure. The bearing setting and the clamping bolt tightening are separate operations; do not substitute a generic hub-nut torque.
• What should I check before ordering? Confirm the 16mm spindle application, M16 x 1 thread and relevant model and chassis restrictions.
