Through the oil deflector plastics that ensure the lubrication of the transfer case, oil is delivered to the necessary components.<\/p>\n
These plastic components are vital for the internal lubrication system. They act as guides to ensure that oil is correctly delivered to the gears, bearings, and clutch packs. Without these deflectors, certain parts of the transfer case would run dry, leading to rapid overheating and mechanical failure.<\/p>\n<\/details>\n While jerking is often related to the actuator motor or worn-out oil, damaged or brittle oil deflectors can cause improper lubrication, leading to internal wear. If you are rebuilding your transfer case to fix a jerking issue, replacing these plastics is essential to ensure the new components stay lubricated.<\/p>\n<\/details>\n This kit is specifically designed for the ATC450 transfer case, which is commonly found in BMW X5 (E70 LCI) and X6 (E71) models produced between 2010 and 2013. We recommend checking the tag on your transfer case to confirm it is an ATC450 unit before purchasing.<\/p>\n<\/details>\n No, the transfer case must be removed from the vehicle and the housing must be split open to access and replace these internal plastic oil deflectors. This is typically done during a full rebuild or a major service.<\/p>\n<\/details>\n Over years of heat cycles and exposure to transmission fluid, the original plastic becomes extremely brittle. They often develop micro-cracks that aren’t easily visible but can cause the part to shatter later. Replacing them during a service is a low-cost way to prevent a catastrophic internal failure.<\/p>\n<\/details>\n<\/div>\nMy BMW X5 is jerking during acceleration; could these plastic parts be the cause?<\/summary>\n
