How to properly replace the Transfer Case Seal in the extension housing on Ford Explorer Sport Trac?

Raise the vehicle and support it securely on jack stands, ensuring that if equipped with Automatic Ride Control (ARC), the air suspension switch is turned to the OFF position to prevent damage to the system components. Place a drain pan under the extension housing, as some transmission lubricant may drain out when the driveshaft slip joint is withdrawn. Remove the driveshaft. Use a seal removal tool to take out the oil seal from the end of the extension housing, being cautious not to damage the housing if using a thin blade screwdriver or chisel instead. Inspect the sealing surface on the driveshaft slip joint for any scoring or burrs that could damage the new oil seal, and replace the yoke if it is damaged. Check the extension housing bore for burrs and remove them with emery cloth or medium grit wet-and-dry sandpaper, then clean the bore with a cloth dipped in solvent. Apply silicone sealant to the outside diameter of the oil seal and multipurpose grease to the seal lip. Using a seal driver, large socket, or section of pipe, install a new oil seal, ensuring it is completely seated and square to the housing. Install the driveshaft, lower the vehicle, and check the transmission lubricant level, topping up if necessary.

Ford Explorer Sport Trac Transfer Case Seal

The Ford Explorer Sport Trac Transfer Case Seal keeps the lubricating fluid trapped inside the transfer case so the gears stay cool and well oiled during every drive, avoiding drops in hydraulic pressure that hurt shifting. This compact circular barrier hugs the output shaft, its spring loaded rubber lip forming a tight interface that stops leaks, and each Transfer Case Seal relies on constant tension from an internal spring. If neglected, a damaged Transfer Case Seal loses tension and quickly lets fluid escape. When the seal fails, puddles collect under an Explorer Sport Trac and the gears can overheat, so modern Ford owners swap in a new Transfer Case Seal right away. Early Explorer Sport Trac years applied a single lip elastomer piece, while later Ford versions switched to a double lip style with a dust wiper, the added lip blocking road grit and extending life. Both designs press flexible material against the spinning shaft, and Ford also fits a bronze extension housing bushing that keeps the yoke centered, because a worn bushing will overwhelm even the greatly strong Transfer Case Seal and negate its protection, keeping the Explorer Sport Trac adventure ready.

We provide a wide range of Ford Explorer Sport Trac Transfer Case Seal at the optimal prices. If you need Ford Explorer Sport Trac Transfer Case Seal, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
