Contract Repair Station Vendor overhauls all Landing Gear assemblies for 'Time' gear change [for our Air Carrier]. Receiving Inspection required of all components. One task requires confirmation of Main Landing Gear (MLG) wiring harness routing in the axles. Found the Left-hand (L-H) MLG wiring incorrect. Outboard (O/B) harness routed to Inboard (I/B) and I/B routed to O/B position. This wiring concerns the Anti-Skid Transducers. See maintenance write-up for Corrective Action. Vendor Repaired Part.
Reporter stated his Station has started doing Landing Gear changes and Receiving Inspections of the Landing Gears for their A320/319 aircraft when they arrive from the Contract Repair Station Vendor. He works as an Inspector and does the wiring inspection prior to the landing gear being installed. After he found the Main Landing Gear (MLG) Anti-Skid electrical wiring harness cross-connected; mechanics were able to snake and reroute the harness wires without having to separate any components. The same incorrect wire routing on MLGs received from overhaul Vendors has happened before.
