Front Upper Lateral Control Arm Left Right For Mercedes S-Class W222 2013-2020 A2223307200 A2223309900

Q1: Which vehicles does this fit? Mercedes-Benz S-Class W222 (2013–2020) per the supplier table; a technical article verifies "left front upper control arm for 2013–2020 W222 and W217 models with 4MATIC". Listings also cover V222 / X222 (S350–S63 AMG). Confirm the exact model and year by VIN.

Q2: Is the left/right side interchangeable? No — this is a mirror pair: Left A2223307200 and Right A2223309900 are side-specific and NOT interchangeable. Order by side.

Q3: What is this arm exactly? The front upper lateral control arm — Mercedes original designation Transverse Control Arm (verified "Front Left/Right Transverse Control Arm", "Front Right Upper Control Arm"). Position: Front Axle, Upper. No electrical damping — a plain mechanical suspension linkage.

Q4: Is this the upper arm? Yes — this is the upper control arm of the W222 front axle (distinct from the front lower arms). Verify the position against the original unit by VIN.

Q5: Do I need to replace both sides at the same time? Same-axle pair replacement is strongly recommended; an old arm on the other side causes uneven geometry and tire wear. Order the pair A2223307200 + A2223309900.

Q6: What should I pay attention to during installation? Tighten all bolts to the workshop-manual torque specifications with the suspension under load; after installation perform a wheel alignment (camber/caster/toe) and check the ride height per workshop manual.

Q7: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.

Q8: Service life and maintenance? Depends on road conditions and climate. Check the bush for cracks and the ball joint for play during routine service; replace the arm if bush wear, play or crash damage is found.

Q9: Are aftermarket alternatives available? The interchange list for these OE numbers is available on request. Order by the exact OE number and confirm the model/year and side by VIN.
