Q1: Which vehicles does this fit? BMW X7 (G07, 2019–present) per the supplier table. European catalog data also lists BMW X5 (2018–…), X6 (2019–…), iX (2021–…) and ALPINA XB7 (2020–…). Confirm the exact model and year by VIN.
Q2: Is the left/right side interchangeable? No — this is a mirror pair: Left 31106893549 and Right 31106893550 are side-specific and NOT interchangeable. Order by side.
Q3: What is this arm exactly? The front lower trailing arm / track control arm — position: Front Axle, Lower, Front. Control-arm type, approx. 3.9 kg per side (catalog). No electrical damping — a plain mechanical suspension linkage.
Q4: Are the other OE numbers in the family the same part? Yes — 31 10 6 878 073/074, 31 10 8 833 467/468, 31 10 8 841 943/944, 31 10 8 846 963/964, 31 10 8 864 693/694, 31 10 8 866 773/774 and 31 12 8 833 467/468 are the same-arm family (BMW/ALPINA OE lists); 31106893549/550 is the current number. Confirm by VIN.
Q5: Is it the complete arm with bush? The arm itself; the matching mounting bush (46277 01), repair kit and wheel-suspension link set are available (catalog-listed) — recommended to replace together.
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? Replace the mounting bush with the arm; 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.
