This lock nut fits on the steering linkage assembly, at the steering rack tie rod end connection. It is used to secure the tie rod end adjustment position and maintain correct steering geometry. Depending on the model, it may be used on the left or right side steering tie rod assembly.
Functions
• Secures the steering rack tie rod end in place
• Helps maintain correct steering alignment and toe adjustment
• Prevents the tie rod end from loosening during use
• Supports accurate steering control and stable handling
• Helps reduce steering play, vibration, or unwanted movement
• Provides an OE Match replacement for the original locking nut
• Suitable for steering rack, tie rod end, and alignment-related repairs
Steering lock nuts are important safety-related fasteners and can lose locking strength after removal. They may also become corroded, rounded, seized, or damaged during steering and suspension repairs. Replacing the lock nut helps ensure the tie rod end remains securely fixed and correctly adjusted after service or wheel alignment.
When to replace
• The steering rack tie rod end has been removed or replaced
• The tie rod end has been adjusted during wheel alignment
• The original nut is corroded, rounded, seized, or damaged
• The nut no longer tightens or locks securely
• There is play, looseness, or vibration in the steering linkage
• Steering rack or front suspension repairs are being carried out
• The nut has been removed and should not be reused

Diagram Ref No 2
Manufactured from premium-grade, oil- and ozone-resistant rubber, the bellow is engineered to withstand continuous flexing, road contaminants, water, heat and harsh environmental conditions. Precision-moulded to match the original component, it allows unrestricted steering movement while maintaining a secure seal around the steering rack and inner tie rod.
What This Product Does:
- Protects the inner track rod and steering rack from dirt and debris.
- Prevents water and contaminants from entering the steering assembly.
- Retains grease around the inner steering joint.
- Allows unrestricted steering movement through its flexible design.
- Helps extend the service life of steering components.
- Maintains smooth steering operation.
- Reduces the risk of premature steering rack wear.
- Forms an essential protective component of the steering system.
Symptoms Of Wear Or Failure:
- Visible cracks, splits or tears in the rubber boot.
- Grease leaking from inside the bellows.
- Dirt or water contamination within the steering joint.
- Knocking or play in the steering system.
- Increased steering stiffness or roughness.
- Premature wear of the inner track rod joint.
- Corrosion on steering rack components.
- Uneven steering feel.
- Steering rack grease contamination.
- MOT or vehicle inspection failure due to a damaged steering boot.
Why Replacement Matters:
- The track rod rubber bellow is continuously exposed to road salt, dirt, water, UV exposure, engine heat and repeated steering movement. Over time, the rubber can harden, crack or split, allowing contaminants to enter the steering rack while permitting lubricating grease to escape.
- Once the protective seal is compromised, the inner track rod joint and steering rack become vulnerable to corrosion and accelerated wear, which can lead to excessive steering play, reduced steering precision and costly steering rack repairs.
- Replacing a damaged rubber bellow restores proper protection for the steering system and helps preserve the condition of the steering rack and inner track rod. An OE Match replacement provides factory-style fitment, excellent flexibility and long-lasting durability, helping maintain the precise steering performance, safety and reliability expected from your Porsche.

Porsche Cayenne 957 2007 - 2010

• Position: Between steering rack housing and boot (bellows)
• Function: Seals the interface to prevent fluid leaks and protect internal rack components
The O-ring can harden, flatten, or crack over time due to heat, fluid exposure, or age.
Replacement is recommended when:
• Replacing or refitting steering rack boots
• Servicing the steering rack or tie rod assemblies
• Evidence of moisture, fluid seepage, or debris inside the bellows
Replacing with a Genuine Porsche N90180902 O-Ring ensures proper sealing, preventing premature wear or corrosion of internal steering components.

Steering Rack Boot Clamp (crimp-type or “ear clamp”)
The Genuine Porsche N10551701 Boot Clamp is the factory clamp used to secure the steering rack bellows / rack boot to the rack housing or tie rod housing. This clamp ensures the boot is sealed tightly, keeping dirt, water, and debris out of the rack assembly and protecting internal steering components.
Sold each, 2 required per vehicle.
Fits:
Porsche Cayenne 955 2003 - 2006
Porsche Cayenne 957 2007 - 2010
Porsche Cayenne 958 2011 - 2017
Diagram ref no 3
• Position: Around the boot (bellows) of the steering rack / inner tie rod connection
• Function: Secures the rubber boot to the housing, maintaining a protective seal to prevent ingress of contaminants
The original clamp can lose tension, corrode, or break over time, leading to:
• Loose or leaking rack boots
• Entry of dirt, water, and debris into the rack
• Premature wear or damage to inner steering rack components
Replace the clamp when installing a new rack boot, after steering rack maintenance, or anytime a clamp looks old, stretched, or corroded. A new Genuine Porsche N10551701 clamp restores a secure, factory-level seal for reliable steering protection.
