Q1: Which vehicles does this fit? Mercedes-Benz GL-Class (X166, 2012–2015) / GLS-Class (X166, 2015–2019) per the supplier table. European catalog data also lists GLE (2015–2019) and M-Class (2011–2015). Confirm the exact model and year by VIN.
Q2: Is the left/right side interchangeable? No — this is a mirror pair: Left A1663300107 and Right A1663300207 are side-specific and NOT interchangeable. Order by side.
Q3: What is this arm exactly? The front lower lateral control arm / track control arm — position: Front Axle, Lower (catalog: "Front Axle Left, Lower"). Aluminium construction, without ball joint (catalog-verified), approx. 6.9 kg. No electrical damping — a plain mechanical suspension linkage.
Q4: What is 292 330 07 00? It is a same-arm family number of the left arm (catalog OE list). Order by the exact OE number; confirm by VIN.
Q5: Is this the lower arm (not the upper)? Yes — this is the lower control arm of the X166 front axle (aluminium, without ball joint — the upper-arm family uses different OE numbers). Verify the position against the original unit by VIN.
Q6: 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.
Q7: 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.
Q8: 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.
Q9: Service life and maintenance? Depends on road conditions and climate. Check the bush for cracks during routine service; replace the arm if bush wear, play or crash damage is found.
Q10: 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.
