Used Audi steering inner/outer tie rod with boot, OEM part number 8E0422821C. This genuine tie rod assembly also replaces numbers 8E0422821, 8E0422821D, and 8E0422821A. It mounts on either side of the front suspension. When the tie rod wears, you'll feel loose steering play or a clunk over bumps, and the boot keeps grease and dirt out of the joint.
