Front Upper Lateral Control Arm Left Right For Mercedes GL-Class X164 2006-2012 A2513300707 A2513300807

Q1: Which vehicles does this fit? Mercedes-Benz GL-Class X164 (2006–2012) per the supplier table. European catalog data also lists M-Class (2005–2011) and R-Class (2005–2014). Confirm the exact model and year by VIN.

Q2: Is the left/right side interchangeable? No — this is a mirror pair: Left A2513300707 and Right A2513300807 are side-specific and NOT interchangeable. Order by side.

Q3: What is this arm exactly? The front upper lateral control arm / track control arm — position: Front Axle, Upper (catalog: "Left, Upper, Front"). Aluminium construction, with ball joint (catalog-verified), approx. 1.4 kg. No electrical damping — a plain mechanical suspension linkage.

Q4: What are 251 330 25 00 and A 251 330 07 07 28? They are same-arm family numbers of the left arm (catalog OE list). Order by the exact OE number; confirm by VIN.

Q5: Is this the upper arm (not the lower)? Yes — this is the upper control arm of the X164 front axle (aluminium, with ball joint — distinctly lighter than the cast-steel lower arm family). 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 and the ball joint for play 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.
