This lock nut fits in the steering and chassis assembly, commonly used at the steering rack tie rod end / track rod end connection. Depending on model and application, M12 x 1.5 lock nuts may also appear in suspension and control arm fastening locations.

This is a small but important OE Porsche hardware item that helps secure critical chassis and steering components to the correct factory standard.

Functions
•  Secures the steering rack tie rod end connection
•  Provides a factory-correct M12 x 1.5 locking fastening point
•  Helps maintain secure attachment of steering and chassis components
•  Supports correct steering geometry and component stability
•  Helps prevent loosening caused by vibration, road loads and suspension movement
•  Suitable for replacement during steering rack, track rod or tie rod end work
•  Maintains OE Porsche fitment and fastening quality.

Lock nuts are designed to provide secure fastening and are often recommended for replacement after removal, especially on steering and suspension components. Over time, the nut can corrode, seize, round off or lose its locking effectiveness. Replacing the original nut with a Genuine Porsche OE M12 x 1.5 lock nut helps ensure the tie rod end or related component is secured correctly and safely. This is especially important on steering components, where correct fastening is essential for accurate steering response and road safety.

When to replace
•   When replacing a steering rack tie rod end or track rod end
•   When removing or refitting steering rack components
•   If the original nut is corroded, seized or damaged
•   If the nut thread is worn or the locking function is compromised
•   During suspension or steering overhaul work
•   After accident repair or chassis component replacement
•   When restoring the car with correct OE Porsche hardware.

Diagram ref no 10

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

Note: For 991.2 Carrera and Targa models (indicated with an asterisk), this steering rack is compatible only with vehicles equipped with rear-axle steering (option code PR 470). If your 991.2 Carrera or Targa does not have rear-axle steering, a different steering rack is required.  

We strongly recommend replacing the power steering pump at the same time as the steering rack. Swarf (metal particles) in the power steering system can circulate and cause damage to both components. If you choose to replace only the steering rack and, upon return of your exchange unit, we discover that the rack bar is scored or contaminated with swarf, this indicates that debris is present in the system. In such cases, we advise replacing the pump as well.
Please note: if we have advised that there is swarf in the system and you choose not to replace both components, any future warranty claims related to this issue will not be valid.

Terms & Conditions - Exchange Purchase:

The surcharge for this product will be refunded only after your existing steering rack has been:

1.) Removed from your vehicle
2.) Returned to us at your own expense
3.) Accepted by the manufacturer as suitable for reconditioning

Please note that the assessment and approval of the returned unit is solely at the discretion of the manufacturer.

Refund processing times typically range from 1 to 2 weeks after the unit is received. However, in some cases, it may take up to 8 weeks for the manufacturer to complete their evaluation and issue approval.

All exchange purchases and surcharge refunds are subject to our full Terms & Conditions, available on our website.

About Steering Parts

Common Porsche Steering Issues

Even the best-engineered Porsche components experience wear over time. Common steering problems include:

  • Low Power Steering Fluid- A frequent cause of heavy or unresponsive steering. Topping up fluid restores smoothness, but continual loss may indicate a leak.
  • Power Steering Leaks - If topping up fluid doesn’t solve the issue, check for leaks. Power steering fluid is usually clear or pink — look for patches under your car when parked.
  • Failing Steering Rack Mounts - Modern Porsches use rack-and-pinion systems. When rack bushings wear out, symptoms include - Jerky steering when going over bumps, Inconsistent wheel feel and Clunking, clicking, or popping noises in the column

If you notice any of these issues, it’s important to get your Porsche inspected by a specialist to prevent further damage.

Diagnosing & Replacing Porsche Steering Components

Steering issues are not always easy to diagnose without specialist knowledge. Our advice: book in with a Porsche specialist garage for a full inspection. They can pinpoint whether the issue is with the rack, joints, bushings, or hydraulics.

If replacement is required, our website makes it simple. Select your Porsche model and year, and we’ll filter the catalogue to show only compatible steering spares for your car.
