The lock nut fastens the control arm to the wheel carrier, helping keep the suspension arm securely mounted in its correct position. This connection is important for maintaining suspension geometry, wheel alignment, and stable handling.  Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.

Functions
•  Secures the control arm to the wheel carrier
•  Helps maintain correct suspension alignment and geometry
•  Supports stable wheel location during driving, braking, and cornering
•  Helps prevent loosening caused by road vibration and suspension movement
•  Provides a secure OE Match replacement for the original lock nut
•  Suitable for suspension repair, control arm replacement, or wheel carrier service

Suspension lock nuts are safety-critical fasteners and may lose locking strength after removal. They can also become corroded, damaged, rounded, or worn over time. Replacing the lock nut during suspension work helps ensure the control arm is secured correctly and reduces the risk of loosening after reassembly.

When to replace
•  This Part The control arm has been removed or replaced
•  The wheel carrier or suspension arm connection has been dismantled
•  The original nut is corroded, damaged, rounded, or seized
•  The nut no longer tightens or locks correctly
•  Suspension repairs or alignment-related work are being carried out
•  There is play, looseness, or noise from the control arm mounting area
•  As recommended during service where single-use locking hardware is removed

This lock nut fits in the suspension assembly, at the control arm to wheel carrier mounting point. Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.

Functions
•  Secures the control arm to the wheel carrier
•  Provides a factory-correct M12 x 1.5 locking fastening point
•  Helps maintain suspension arm stability and alignment
•  Prevents loosening caused by road vibration and suspension movement
•  Supports correct suspension geometry and wheel control
•  Helps ensure safe and secure mounting of chassis components
•  Provides OE Porsche fitment, thread size and fastening quality.

Control arm lock nuts are exposed to road dirt, moisture, corrosion and high suspension loads. Over time, the nut can corrode, seize, round off or lose its locking ability. Because this fastener secures a critical suspension joint, it is good practice to replace it whenever the control arm is removed or replaced.

Using a Genuine Porsche OE lock nut helps ensure the control arm is correctly secured to the wheel carrier and maintains the factory-standard suspension assembly.

When to replace
•  When replacing a control arm, wishbone or coffin arm
•  When removing or refitting the arm-to-wheel-carrier joint
•  If the original nut is corroded, seized or damaged
•  If the thread is worn or the locking function is compromised
•  During suspension overhaul or chassis repair work
•  After accident repair or wheel carrier replacement
•  When restoring the suspension with correct OE Porsche hardware.

What This Product Does:

• In place of soft rubber bushings, the monoball bearings provide a rigid, low-deflection pivot for the control arms, while still allowing the required angular motion (rotation / articulation) of the suspension.
• Because spherical bearings respond with minimal deflection, the control arm geometry (camber, toe) remains more consistent under load (cornering, braking, acceleration).
• The rigid nature of monoballs helps maintain steering precision and sharper feedback by eliminating rubber compliance (i.e. “mushy” behavior) that would otherwise absorb inputs or distort geometry.
• The Teflon lining ensures smooth motion with minimal friction and wear inside the bearing.

Symptoms Of Worn Or Failing Rubber Bushings:

• Looseness or “play” in steering / feeling soft in the front suspension
• “Wobble” or slight deflection under hard cornering or directional changes
• Changes in alignment under load — e.g. toe or camber drifting
• Poor steering feedback, especially over undulations or when pushing the car
• Vibration, harshness, or unwanted compliance in suspension response

Why Upgrading To Monoball Matters:

• Sharper steering response & feedback — no rubber compliance dulling input
  
• Better alignment retention under load — more consistent camber / toe through suspension travel
  
• Greater precision in handling, especially during cornering, transitions, or high lateral forces
  
• Less geometry distortion when pushing the car hard or under braking
  
• Durability under load — well-made monoball bushings resist deformation better than aged or overworked rubber
  
• Ideal for motorsport / track setups where predictability and consistency matter more than comfort

What This Product Does:

• The bushing is the interface between the control arm and the subframe / mounting point.
• It permits controlled movement (for suspension travel) while resisting unwanted motion so the wheel alignment remains stable.
  
• The firmer (sport) version deflects less under cornering, braking, or acceleration loads, helping maintain alignment geometry under load.
  
• By resisting deflection, it helps reduce unwanted movement in the front suspension, improving handling precision and steering feedback.

Symptoms Of A Worn / Failing Bushing:

• Vibration felt in the steering wheel, especially under certain loads or speeds (“shudderiness”)
• Looseness / play in the front suspension — less precise steering response
  
• Alignment changes under load — the front toe may drift during cornering or braking
  
• Clunking or knocking noises over bumps or from the front suspension
  
• Uneven or increased tire wear, especially on the front edges
  
• A degraded “feel” to the front end — less sharpness or a vague response in turns

Why The Sport Hardness Version Matters:

• Better control under load: Because this bushing is stiffer than stock, it deflects less in aggressive driving, helping maintain suspension geometry (camber / toe) more accurately in dynamic conditions.
  
• Sharper steering feel: Less compliance means more direct response, reducing mushiness in the front end.
  
• Reduced suspension movement / slop: Particularly helpful in performance, track, or spirited road use where loads are higher.
  
• Longer service life (in some cases): A harder compound may resist aging and fatigue better in high-stress conditions, though it may transmit slightly more noise, vibration compared to softer rubber.
  
• It still retains enough flexibility to absorb some road input, balancing performance with comfort.

What This Product Does:

• This bushing sits at the front mount of the control arm, connecting it to the subframe or chassis. It allows the control arm to pivot as the suspension moves vertically, but resists unwanted lateral or rotational movement.
  
• Under lateral or braking / acceleration loads, the bushing helps maintain toe, camber, and alignment stability by resisting flex.
  
• The sport / hardened version is designed to reduce compliance (i.e. reduce unwanted movement), giving crisper steering feel and better handling under dynamic loads.

Symptoms / Signs Of Wear Or Inadequacy:

• Vibration or shudder in the steering wheel, especially under load or during cornering
• A vague or “wandering” front end feel
• Alignment changes under cornering or braking (toe drift)
• Uneven or accelerated tire wear
• Noises (clunks or creaks) from the front suspension under load
• Reduced steering precision / less sharp handling

Why the Sport / Heavy Duty Version Matters:

• Reduced Deflection: Because the harder compound flexes less under load, alignment remains more consistent during aggressive driving or cornering.
  
• Sharper Steering Feedback: Less “softness” gives more direct, responsive feel between steering input and front-end behavior.
  
• Better Handling Under Load: Under heavy loads (cornering, braking, etc.), the harder bushing helps maintain geometry more faithfully.
  
• Durability: Upgraded compounds often resist fatigue, heat, and aging better than soft original rubber, especially in sporty or track use.

• 964 / 993 front lower control arm rear bushing
• 944 front lower control arm front bushing (aluminium arms)

It used to be a difficult task

This clever tool is a real time saver that makes easy work of removing split bushings. Doing the job with the arms still on the car for 911, 964, and 993 saves time and labor.

Split bushings are actually two separate bushings, each pressed in from opposite sides of the arm. Removing them requires driving them out from the parting line where they meet, in the center of the arm. This has traditionally been a difficult job that requires removing the arm and fumbling with a punch to try and drive out the bushings from the center.

Easy & quick
This tool makes it easy to engage the parting line and drive out the bushing. It is so easy that the job can be performed without removing the arm from the 911, 964, and 993.

Pro Mechanics and DIY'ers alike will appreciate the time saving this tool provides.

Combine with bushing installation tools part #2020904 to complete the job.
