Delphi Lateral Arm P/N:TC3220
Delphi TC4940 rear lower lateral arm for the 2021 Tesla 3 locates the rear wheel side to side as the suspension moves.
A worn lateral arm can show up as a clunk over bumps from the rear suspension, uneven rear tire wear or an alignment that keeps drifting. Before you replace it, rule out worn rear shocks, loose wheel hardware and tire problems, which can make similar noises. This listing is one arm; both sides are normally replaced together.
This arm is a direct-fit replacement for the 2021 Tesla 3, which takes two.
