The Moog Tie Rod End is a direct-fit replacement for Audi A4 models built from 2016 to 2021. Thread pitch, taper and stud length match the factory part exactly, so no shimming is needed. Play in this joint shows up as vague steering, uneven tyre wear and a knock over sharp bumps. Ball studs are induction hardened and fitted with a sealed dust boot to keep water and grit out. Steering components should always be replaced in pairs and followed by a four-wheel alignment. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Supplied new and backed by a 12 Months warranty.
