Dorman 526-845 front left lower control arm with ball joint for the 2017-2025 Audi A4 and other vehicles links the wheel to the suspension. This Dorman control arm and ball joint assembly is a direct replacement for the original equipment on specific vehicle applications.
A clunk over bumps, loose or wandering steering or uneven front tire wear can mean a worn control arm or ball joint. Sway bar links, tie rods, struts or tires can be behind these signs too, so find the cause before you buy. This listing is one arm for the front left; the front right is a separate part, and the two are normally replaced together.
The fitment covers a wide range of Audi models, led by the 2017-2025 Audi A4, the 2021-2025 Audi A5 and the 2021-2025 Audi RS5. If your car is not one of those, open the Buyer's Guide tab and look up your exact model and engine.
