Feeling a shake or hearing a clunk? Your S5's steering precision might be compromised by a worn tie rod end.
- A mandatory wheel alignment is required immediately after replacing a tie rod end to prevent rapid tire wear.
- Symptoms of failure include a shaky steering wheel, clunking noises, and uneven tire wear.
- It is highly recommended to replace outer tie rod ends in pairs to ensure balanced steering and save on future alignment costs.
- Brands like TRW and Lemfoerder are often OEM suppliers for Audi, offering factory quality, while Moog is a reputable premium aftermarket option.
Is Your S5's Steering Feeling Off?
A worn steering tie rod end on a 2014-2018 Audi S5 can make the car feel less responsive and unpredictable. Because this part is constantly moving, it is subject to wear and tear from normal driving and road hazards. Ignoring the symptoms can lead to more significant problems, including premature tire wear and, in severe cases, a loss of steering control.
Symptoms of a Failing Tie Rod End
Identifying a bad tie rod end early can save you from more costly repairs. Here are the common signs to watch for:
🎬 Watch: A visual guide to common tie rod failure symptoms- Shaky or Vibrating Steering Wheel: You may feel a vibration or shaking in the steering wheel, which often gets worse as you accelerate or turn.
- Clunking or Knocking Noises: A distinct clunking or rattling sound from the front of the car, especially at low speeds or when turning, points to a loose joint.
- Loose or Vague Steering: If the steering feels like it has a "dead spot" or excessive play, it means the connection between your steering wheel and the wheels is no longer tight. 🎬 See how to professionally diagnose a bad outer tie rod end
- Uneven Tire Wear: A failing tie rod end will throw off the wheel alignment, causing the edges of your front tires to wear out much faster than the rest of the tread.
- Vehicle Pulling to One Side: Misalignment caused by a bad tie rod can make your S5 pull to the left or right, forcing you to constantly correct the steering.
Safety First
A worn tie rod end is a serious safety concern. If the joint fails completely, you could lose steering control of that wheel. It is not safe to drive with a known tie rod deficiency.
Choosing the Right Aftermarket Tie Rod End
For your Audi S5, you don't have to buy from the dealer to get a quality part. Many aftermarket brands offer excellent replacements. Some, like TRW, are often the original equipment (OE) supplier for German automakers. Here’s a breakdown of available brands to help you choose:
- OEM-Equivalent Quality (TRW, Delphi, Lemfoerder): These brands are known for manufacturing parts to original equipment standards. TRW, in particular, is often a direct supplier to Audi. Choosing one of these brands gives you confidence in fit and longevity, similar to the factory part.
- Premium Aftermarket (Moog, Mevotech): Moog is a well-regarded brand known for durable, all-metal designs that often exceed OE specifications. Mevotech also offers quality parts, sometimes with design improvements over the original. These are a solid choice for owners looking for high performance and durability.
- Standard/Budget-Friendly (Dorman, Beck Arnley, Suspensia, Vaico): These brands provide a cost-effective solution for repairs. They are a good option for daily driving, but may not have the same long-term durability or advanced features as the premium brands.
Pro Tip: It is highly recommended to replace tie rod ends in pairs. If one side has failed due to mileage and wear, the other side is likely not far behind. This also ensures even steering response and saves you from having to pay for a second alignment down the road.

Frequently Asked Questions
Do I absolutely need a wheel alignment after replacing a tie rod end?
Yes, an alignment is mandatory. Replacing a tie rod end, no matter how carefully, will change your vehicle's toe alignment. Skipping the alignment will cause poor handling and rapid, uneven tire wear, quickly costing you more than the alignment itself.
What's the difference between inner and outer tie rod ends?
Most cars have both an inner and an outer tie rod end on each side. The outer tie rod end connects to the steering knuckle at the wheel and is the part that fails most often. The inner tie rod end connects to the steering rack and is protected by a flexible boot. This article focuses on the outer tie rod end, which is the more commonly replaced component.
Can I replace just one tie rod end?
While you can replace just the one that has failed, it is best practice to replace them in pairs (both outer tie rod ends at the same time). The parts on both sides of the car experience the same amount of wear, so if one is worn out, the other is likely near the end of its life. Replacing both at once saves on labor and alignment costs.
Is this a difficult DIY job?
For a home mechanic with the right tools, replacing an outer tie rod end is a manageable job. It typically takes 1-2 hours per side. You will need a jack, jack stands, a socket set, wrenches, and a special tool called a tie rod separator or puller to disconnect the old part from the steering knuckle. 🎬 Watch this step-by-step replacement walkthrough for the Audi B8 chassis However, you must still take the car to a professional shop for a wheel alignment immediately after the repair.
