Replacing the arms as a matched pair ensures both sides of the rear suspension behave consistently, restoring proper balance and eliminating issues caused by uneven bushing wear. It provides equal camber and toe adjustment range on both sides, making alignment more accurate and stable. The result is improved road feel, better stability under load and more predictable handling in every driving situation.

Rear track rod arms are central to maintaining correct wheel alignment and rear-axle control. Over time, bushings and ball joints degrade, leading to:
• Rear-end instability or “float” at speed
• Excessive or uneven tyre wear
• Clunking or knocks over bumps
• Poor alignment accuracy or inability to hold settings
• Vague or inconsistent handling.

Replacing both arms ensures the rear suspension operates to factory geometry and delivers the crisp, stable driving feel Porsche intended.

 Supersession: Part 90037805109 is superseded by 90037805101

This bolt secures the rear suspension control arm to the wheel carrier or subframe, providing the clamping force needed to maintain accurate suspension alignment and minimize movement under load.

Over years of service, high torque loads, vibration, and exposure to road conditions can weaken or corrode suspension bolts. A compromised bolt may lead to improper alignment, handling instability, or noise under braking and cornering.

When to replaces:
• During control arm replacement, alignment service, or rear suspension rebuilds
• If original bolts show corrosion, stretching, or thread wear
• As part of preventive maintenance when reassembling load-bearing suspension joints

Replacing with Genuine Porsche hardware ensures structural integrity, precise fit, and lasting performance.

Since the control-arm mounting bolt bears major structural loads and undergoes vibration and torque stress, it can become worn, stretched, corroded or fatigued over time. This reduces its ability to maintain correct alignment and clamping force - potentially resulting in handling issues or component wear. Replacement is especially important when performing rear suspension service, control arm replacement, or alignment work. Installing the correct bolt restores reliable mounting integrity and ensures the rear axle geometry remains stable under load.
