Common Problems This Seal Can Address

• Transfer case fluid leaking from the front output shaft area
• Contamination entering the seal area and affecting sealing performance
• Seal wear from age, heat, or shaft surface imperfections
• Fluid loss that can leave the transfer case low on lubricant
• Noise or driveline concerns related to low transfer case fluid

Installation Notes and Tips

• Confirm the transfer case model before installation; this seal is listed for New Process 231 and 233 applications.
• Inspect the output shaft surface for grooves, corrosion, or damage before installing the new seal.
• Clean the seal bore and surrounding area so the seal seats evenly.
• Apply appropriate lubricant to the seal lip during installation to reduce dry start-up wear.
• Install carefully to avoid distorting the reinforced outer case.
