Front Upper Lateral Control Arm For VW Touareg Porsche Cayenne 958 7P0407021 95834105100

Q1: Which vehicles does this fit? VW Touareg (NF, 2010–2018) and Porsche Cayenne (958, 2010–2018) per the supplier table and catalog. Confirm the exact model and year by VIN.
Q2: Is this part side-specific? No — OE 7P0407021 / 95834105100 is one part number for BOTH sides (catalog: "Left AND Right" / "both sides"). Order one piece per side (two pieces for a full front-axle replacement).
Q3: What is this arm exactly? The front upper lateral control arm / track control arm — position: Front Axle, Upper. Aluminium construction, with ball joint (catalog-verified), thread M12*1.5, approx. 0.9–1.15 kg. No electrical damping — a plain mechanical suspension linkage.
Q4: Are 7P0407021 and 95834105100 the same part? Yes — both OE numbers are cross-listed on both brand pages in the catalog (same arm). Order by either number; both are listed in the pack.
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.
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 by VIN.
