What It Helps Address

• Transfer case fluid seepage at the rear output shaft
• Contamination entering the seal area from road debris or moisture
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor shaft surface imperfections
• Seal damage during installation on the transfer case housing

Installation Notes

Verify transfer case ID, shaft location, and housing style before installation. Clean the sealing surface thoroughly, inspect the output shaft for wear or scoring, and seat the seal evenly to avoid distortion. Confirm rear-position fitment against the vehicle listing, especially on Jeep Wrangler, Dodge Ram 1500, and Dodge Dakota transfer case applications.
