Audi RS5 Steering Tie Rod End Replacement Guide (2018-2024)
Restore the sharp, responsive steering your Audi RS5 was built for.
- A wheel alignment is not optional; it is a mandatory step after replacing a tie rod end.
- For a performance car like the RS5, choosing a premium aftermarket brand (like Delphi, Moog, or Mevotech Supreme) is recommended to maintain handling.
- Symptoms include clunking noises when turning, loose steering feel, and uneven tire wear.
- It is best practice to replace outer tie rod ends in pairs to save on future labor and alignment costs.
Is Your RS5's Steering Feeling Off?
The steering on the Audi RS5 should feel tight, direct, and responsive. When a tie rod end starts to wear out, that precision is lost. These parts are wear-and-tear items, and the extra stress from the RS5's performance capabilities and larger wheels can lead to replacement needs. Ignoring the symptoms can lead to unsafe driving conditions and damage to other components, like your tires.
Symptoms of a Failing Tie Rod End
- Clunking or Knocking Noises: A distinct clunk or knock from the front end when turning at low speeds is a classic sign of a worn tie rod end.
- Loose or Vague Steering: You might notice a "dead spot" when you turn the steering wheel, or the car may feel like it's wandering on the road, requiring constant small corrections.
- Steering Wheel Vibration: A shaky or vibrating steering wheel that gets worse as you accelerate or turn can point to a loose tie rod.
- Uneven Tire Wear: A bad tie rod end will throw off your wheel alignment, causing the inside or outside edge of your front tires to wear down much faster than the rest of the tread.
Known Issues and Recalls
Searches of the NHTSA database and technical service bulletins (TSBs) did not show any specific recalls for premature steering tie rod end failure on the 2018-2024 Audi RS5. However, TSBs exist for other steering system issues on this platform, such as noises from the steering shaft boot and electronic steering warnings. It is important to correctly diagnose the issue, as a noise from the front end is not always a tie rod problem.
Choosing the Right Aftermarket Tie Rod End
For a performance car like the RS5, the quality of suspension components matters. While saving money is always a plus, installing a low-quality part can ruin the driving experience and may not last long. Here’s a breakdown of aftermarket brand tiers to help you decide.
Tier 1: Premium & OE-Equivalent Brands
These brands are focused on meeting or exceeding original equipment (OE) specifications. They are the best choice for owners who want to maintain the RS5's original handling and performance characteristics.
- Delphi: A well-respected OE supplier for many car manufacturers. Delphi parts are known for their quality engineering and durability, making them a very safe bet.
- Moog: Traditionally a top-tier name in chassis parts. While some forum users have debated their recent quality, their "Problem Solver" line is generally considered a strong, durable option.
- Beck Arnley: Specializes in parts for import vehicles and focuses on matching the OE form, fit, and function. A reliable choice for maintaining factory performance.
Pro Tip: The original Audi tie rod ends are often made by companies like Lemförder or TRW. If you see these brands available, they are excellent choices and are essentially the same as the genuine Audi part without the dealer markup.
Tier 2: Mid-Grade & Heavy-Duty Brands
These brands offer a good balance of quality and price. They are a solid choice for daily driving and can sometimes offer features not found on stock parts.
- Mevotech: A popular brand with several product lines. Their "Supreme" or "TTX" (Tough Terrain eXtreme) lines are often considered equal to or even more durable than other premium brands, sometimes featuring enhanced designs and corrosion resistance.
Tier 3: Economy Brands
These brands prioritize cost savings. While they will function, they may not offer the same longevity or precision as higher-tier options. For a vehicle like the RS5, these should be considered with caution.
- Dorman: Known for providing a vast catalog of affordable replacement parts. While functional, they are generally not considered a performance-oriented brand.
- Suspensia: Positioned as a value-oriented brand, offering a basic replacement to get the job done at a low cost.

Frequently Asked Questions (FAQ)
Do I absolutely need a wheel alignment after replacement?
Yes, 100%. Replacing a tie rod end will always change the toe alignment of your wheel. Skipping the alignment will cause the car to handle poorly, pull to one side, and rapidly destroy your tires. The cost of an alignment is small compared to the cost of new performance tires for an RS5.
Should I replace tie rod ends in pairs?
It is highly recommended. If one side has failed due to wear, the other side is likely not far behind. Replacing both at the same time saves you from having to do the job again soon and paying for a second wheel alignment.
What's the difference between inner and outer tie rod ends?
The outer tie rod end connects to the steering knuckle at the wheel, and it's the most commonly replaced part. The inner tie rod end connects to the steering rack itself, under a protective boot. This guide focuses on the outer tie rod end, which is the part that typically fails first.
How does a bad tie rod end affect my RS5's performance?
A worn tie rod end introduces slop into the steering system. This completely undermines the RS5's sharp handling, making turn-in feel vague and reducing driver confidence. In a corner, the affected wheel can have a slight, uncontrolled change in direction, which is unsettling and unsafe in a high-performance car.
