Part Number: W0133-1618933
Notes: Vehicles using this axle MUST have the original heat shield around the y-pipe and front catalytic converter and have the fuel mixture properly adjusted. Missing heat shields or improperly set fuel mixture can cause the inner axle boots to overheat and eventually split, resulting in loss of lubricant and/or contamination of the inner CV joint, leading to failure of the joint. FAILURES OF THIS NATURE ARE NOT COVERED BY THE AXLE MANUFACTURER'S WARRANTY!!!! - Differential fluids should be changed and the proper additives should be used before installing axles on Subaru vehicles. Replacing fluids in the front, rear and especially center differential is recommended. Shuddering and noise are often attributed to axle shafts can be due to contaminated lubricants, worn suspension bushings or Ball Joints.
