Audi steering tie rod with boot, OEM part number 4M0423812D (right side). This used genuine Audi part also replaces 4M0423812B and 4M0423812C. It's the right-side tie rod assembly that connects the steering rack to the front wheel, controlling directional stability. A worn tie rod can cause loose steering feel, uneven tire wear, or a clunking noise when turning. This part fits multiple Audi models with engines including 2.0L turbocharged four-cylinder, 3.0L supercharged V6, 3.0L diesel V6, 4.0L twin-turbo V8, and various hybrid powertrains.
