Inspection and Verification

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the customer concern.
  2. Inspect for obvious signs of mechanical damage.
    • PTU 
    • Halfshafts and CV  joints
    • Driveshaft and Universal Joint (U-Joint)
    • Wheel/tire size and brand
    • Tire pressure
  3. NOTE: The PTU  may leak different color fluids, red for automatic transmission fluid and brown/black gear lube for PTU  fluid. The PTU  seals prevent these types of fluids from leaking externally. It is important to note which color of fluid is leaking to determine the most appropriate service procedure.

    Inspect for obvious leaks.

    • Cover seal
    • Output shaft seal
