Restore or maintain the alignment-adjust capability of your Porsche 928’s rear suspension with this eccentric bolt. Designed for the 1986–95 928 series (including S2, S4/GT, GTS), this offers direct replacement for the original rear trailing arm / cross-member adjuster. By repositioning the bolt within its eccentric housing, precise adjustment of camber or toe is achievable — helping lock the rear geometry securely and ensuring accurate, stable handling. Sold individually (two recommended per vehicle), this adjuster bolt is a key maintenance item when refreshing the rear suspension or correcting alignment issues.

What This Product Does:
- The eccentric bolt is part of the rear suspension trailing arm / cross-member assembly. It allows for precise adjustment of the rear suspension geometry — typically for camber, toe or longitudinal arm position via the eccentric nature of the bolt.
- Being “eccentric” means the bolt shaft is offset inside its housing so that when the bolt is rotated or repositioned, the trailing arm or mount moves slightly (i.e., the arm moves in or out by a small amount) to allow alignment adjustment.
- It helps set and maintain correct alignment (especially toe and camber) of the rear suspension arms relative to the body and chassis — critical for handling, stability and tyre wear on the 928’s rear suspension.
- When adjusted correctly and properly torqued, the bolt holds the arm or cross-member in its correct location and prevents unwanted movement or geometry shift under load.
Symptoms Of Wear, Mis-Adjustment Or When It Needs Attention:
- The rear alignment is out of specification or cannot be held — especially rear toe or camber that keeps shifting or adjusting.
- Unusual tyre wear on the rear tyres — inner or outer edge wear due to geometry changes under load.
- Rear instability or vague handling — the car may feel less precise, especially in corners or under acceleration/braking, because the arm location isn’t locked down.
- Loose or knocking noises at the rear suspension — if the eccentric bolt or its housing is worn, movement might occur.
- During inspection, you find the eccentric bolt is corroded, seized, has stripped threads, or the slot for adjustment is damaged — making accurate adjustment impossible.
- After a suspension service or arm replacement, the bolt or its seat looks malformed or the previous adjustment marks don’t align — indicates repeat adjustments or wear.
Why Replacement Matters:
- Ensuring the eccentric bolt is in good condition and correctly torqued is fundamental to rear suspension geometry, which directly influences handling, stability, and tyre life especially in a high-performance car like the 928.
- A worn or sloppy adjuster can allow the arm to shift under load — reducing precision, creating instability, and wearing tyres faster.
- In restoration or performance setups (larger tyres, stiffer springs, lowered ride height) the demands on geometry tighten — having a firm, adjustable mount is critical.
- Replacing the bolt or upgrade stiff fixation means alignment stays correct for longer, adjustments are reliable, and the suspension performs as designed.
- From a safety viewpoint, correct alignment and arm location help ensure the vehicle behaves predictably in high-load or hard-cornering scenarios.

Rear Suspension Bearing Pin - fits Left or Right Hand Side
Restore the integrity and serviceability of your Porsche 928
rear suspension with this OE Match Rear Suspension Bearing Pin.
Manufactured to original Porsche specifications and finished with a durable
galvanised coating for long-term corrosion protection, this replacement bearing
pin is supplied complete with two new fixing nuts for a professional-quality
installation.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
- Porsche 928S4 5.0L 1987-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
Diagram ref no 17
Suitable for all Porsche 928 model years from 1978 to 1995,
including the highly desirable GTS models, this suspension bearing pin forms a
critical mounting point within the rear suspension assembly. It is the primary
fixing bolt that secures the rear shock absorber to the rear axle wheel carrier
and plays an essential role in maintaining suspension geometry, stability and
ride quality.
What Does the Rear Suspension Bearing Pin Do?
The rear suspension bearing pin acts as the main fixing point between the rear shock absorber and the rear suspension carrier assembly.
Its primary functions include:
- Securing the rear shock absorber
- Maintaining suspension alignment
- Supporting suspension movement
- Helping control wheel motion
- Preserving ride quality
- Supporting vehicle stability
- Maintaining safe suspension operation
Without a correctly fitted and structurally sound bearing pin, the rear suspension cannot function as designed.
Why Do Rear Suspension Bearing Pins Fail?
Although manufactured from high-strength steel, these bolts are exposed to decades of road use and harsh environmental conditions.
Common causes of deterioration include:
- Corrosion from water and road salt
- Galvanic corrosion between suspension components
- Long-term moisture exposure
- Seizure within the suspension carrier
- Thread damage during removal
- Age-related deterioration
- Previous incorrect installation
- Suspension refurbishment work
Many original bolts become heavily corroded, often making removal extremely difficult during suspension repairs.
Common Problems During Removal
On many Porsche 928 models, including low-mileage and well-maintained vehicles, the original bearing pin can become seized within the rear wheel carrier and shock absorber mounting.
In severe cases:
- The bolt may be impossible to remove conventionally
- The shock absorber lower mount may need cutting away
- Corroded hardware may require grinding off
- Hydraulic pressing equipment may be needed to remove the seized pin
- Replacement hardware becomes essential during reassembly
This is why replacement bearing pins are commonly fitted whenever rear suspension refurbishment or shock absorber replacement is carried out.
Symptoms of a Worn or Damaged Bearing Pin
Potential warning signs include:
- Corrosion visible on the bolt
- Damaged threads
- Suspension looseness
- Difficulty tightening to specification
- Excessive wear during inspection
- Movement within the mounting point
- Signs of previous corrosion damage
Even if no symptoms are present, heavily corroded original hardware should be replaced during suspension work.
When Should the Rear Suspension Bearing Pin Be Replaced?
Replacement is recommended when:
- Replacing rear shock absorbers
- Restoring rear suspension components
- Corrosion is present
- Removing seized original hardware
- Performing preventative maintenance
- Carrying out a full suspension rebuild
- Restoring a Porsche 928 to factory condition
Most Porsche specialists replace these bolts as a matter of course whenever the rear shocks are removed.
Why Replacement Matters
Replacing ageing suspension hardware helps ensure long-term reliability and ease of future servicing.
Benefits include:
- Improved corrosion resistance
- Reliable suspension mounting
- Correct factory fitment
- Improved serviceability
- Enhanced safety
- Long-term durability
- Professional restoration quality
- Reduced future maintenance issues
The galvanised finish provides excellent protection against corrosion, helping the new bearing pin remain serviceable for years to come.
