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

• Thread: M16 x 1.
• Spindle application: 16mm front spindle.
• Design: Original rounded-style clamping nut.
• Included fixing: Clamping bolt.

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.

Required Quantity
Two required per car for the applicable front spindle arrangement. Sold individually, with a bolt.

What Is This Part?
This is the threaded clamping nut used at the outer end of the front wheel spindle. It works with the thrust washer and wheel-bearing assembly to retain the hub and establish the bearing adjustment. The clamping bolt secures the nut once the adjustment has been set. Its condition is therefore relevant whenever the front hub is removed or the wheel bearings are inspected or renewed.

What Does This Part Do?

• Retains the bearing assembly: Threads onto the front spindle and works with the thrust washer to hold the assembly in position.
• Allows bearing adjustment: Provides the threaded adjustment point used when setting front wheel-bearing clearance.
• Secures the setting: Uses its clamping bolt to hold the nut at the adjusted position.
• Completes the retaining arrangement: Works alongside the spindle, thrust washer and bearings rather than replacing those supporting components.

Why Replace This Part?
Replacement may be necessary if the nut has damaged threads, a cracked or distorted clamping section, or corrosion that prevents correct adjustment. Damage around the bolt fixing can also prevent the nut from being secured properly. Check the spindle threads and associated washer at the same time, as replacing the nut alone will not correct damage elsewhere in the assembly.

During wheel-bearing work, inspect the existing nut before deciding whether it can be refitted. Do not assume this clamping nut follows the tightening procedure used for a conventional driveshaft nut: use the vehicle-specific bearing adjustment and clamping-bolt instructions.

When to Replace This Part?

• Damaged threads: The nut binds, cross-threads or will not engage correctly on an undamaged spindle.
• Cracks or distortion: The clamping section is visibly damaged or no longer seats correctly.
• Damaged bolt fixing: The bolt or its threaded fixing cannot secure the nut as required.
• Significant corrosion: Deterioration affects the threads, seating face or clamping action.
• Persistent wheel play: Inspect the nut, bearing adjustment, bearings and spindle together; movement alone does not identify the nut as faulty.
• Removal damage: Renew the nut if dismantling has left it unsuitable for correct adjustment and refitting.

Where Is This Part Fitted?
Location: At the outer end of the front wheel spindle, alongside the thrust washer and outer wheel bearing in the front hub assembly.

Technical Details

• Thread: M18x1.
• Spindle application: 18mm front spindle.
• Supplied assembly: Clamping nut with bolt.

FAQs

• Can I reuse the existing nut? Inspect its threads, clamping section and bolt fixing, then follow the vehicle-specific workshop instructions. Replace it if damaged or if renewal is specified.
• Will a new nut cure wheel-bearing noise or play? Not necessarily. Bearing wear, incorrect adjustment and spindle damage can produce similar symptoms, so inspect the complete assembly first.
• How should it be tightened? Follow the correct bearing adjustment procedure and clamping-bolt specification for your model. No universal torque value should be assumed.
