Information
Steering rack boot seal ring.
Located inside the steering rack housing (rack & pinion assembly) as an inner seal ring around gear housing/rack interface — critical for containing hydraulic fluid and ensuring rack integrity.
Sold each, 2 required per vehicle.
Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012

Porsche 997.2 2009 - 2012
Diagram ref no 4
Even though it’s a small part, the seal ring plays a vital role in your Porsche’s hydraulic steering system. When it fails, you may experience fluid leaks, loss of hydraulic assist, play in the steering or reduced feedback - all affecting handling, safety and longevity of steering components. Replacing the seal ring with the genuine part restores correct sealing, hydraulic pressure retention and the precise steering feel your Porsche expects.
When and why to replace:
• Evident steering fluid seepage around the rack housing or boots, indicating internal seal failure.
• Loss of power-steering assist or degraded steering feel, especially at low speeds or when cold.
• During steering rack replacement or rebuild – when bearing access is available and you want to prevent future leaks.
• As part of front-end or steering system overhaul on high-mileage vehicles where original seals may have aged or hardened.
• Whenever the steering rack hydraulic system is opened or dismantled – fitting a new genuine seal ring ensures proper long-term service.

Track rod, manual steering.

The tie rod assembly connects the steering rack to the front wheels, transferring your steering input directly to the wheels. It ensures the wheels turn precisely when you move the steering wheel, keeping the car stable, responsive, and safe on the road.
If the tie rod wears out, steering can become loose or unresponsive, tire wear may increase, and overall handling can suffer. Replacing it restores accurate steering control and proper suspension alignment.
Signs of Wear:
• Excessive play or looseness in the steering wheel
• Steering feels unresponsive or “loose” while driving
• Noticeable movement when the tie rod is gripped and moved by hand

Track rod end.

The steering rack controls the front wheels by means of two track rods, terminated by replaceable joints - the "Track Rod Ends", attached to the swivel hubs. These will eventually wear, leading to problems with steering and handling, as well as being a failure point on the UK MOT and presumably on the statutory inspections in other countries.
