Steer with confidence and keep your front wheel tracking true with the Dorman - OE Solutions Steering Tie Rod End 543-921. This front left outer tie rod end drops in as a direct-fit replacement for a wide range of BMW and MINI models, including the 2020-2024 BMW 118I, 2016-2019 BMW 220I, 2016-2022 BMW X1, 2018-2023 BMW X2, and 2014-2025 MINI COOPER — see the Buyer's Guide tab for the full list.
- Position: front left outer tie rod end for the listed applications.
- Function: connects the steering linkage to the left front steering knuckle, transmitting steering input to the wheel and providing the connection point for toe (alignment) adjustment.
- Articulating joint: the ball stud and socket let the tie rod end pivot as the wheel steers and the suspension moves.
Signs a tie rod end may need replacing include loose or wandering steering, uneven or feathered front tire wear, and a knocking or clunking felt through the wheel when turning or crossing bumps. Because these symptoms can have other causes, diagnose the joint before replacing. If a worn front left outer tie rod end is the cause, this unit replaces the original; have a wheel alignment performed afterward.
