How to replace the Transfer Case Seal in the extension housing of a transmission without removing it from the Nissan Armada?

Oil leaks frequently occur due to wear of the extension housing oil seal, which is relatively easy to replace without removing the transmission from the vehicle. The extension housing oil seal is located at the extreme rear of the transmission, where the driveshaft is attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jackstands. A leaking seal will result in transmission lubricant building up on the front of the driveshaft and possibly dripping from the rear of the transmission. For models equipped with a rear auto-leveling suspension, turn the ignition key to the OFF position before raising the vehicle. Remove the driveshaft, then use a seal removal tool or a large screwdriver to carefully pry the oil seal out of the rear of the transmission, ensuring not to damage the splines on the output shaft. Install the new oil seal using a seal driver or a very large deep socket as a drift, driving it into place squarely and ensuring it is completely seated. Finally, lubricate the splines of the transmission output shaft and the outside of the driveshaft yoke with lightweight grease before reinstalling the driveshaft, taking care not to damage the lip of the new seal.

Nissan Armada Transfer Case Seal

The Nissan Armada Transfer Case Seal holds lubricant inside the transfer gears to avoid losing fluid that would overheat and damage drivetrain components. The Transfer Case Seal forms a tight seal around the output shaft to hold oil, which allows the gears to turn in response to input from the transmission. This allows your four wheel drive to function reliably. Puddles under the case, loss of lubricant, rapid friction, and heat damage to the gears is what happens on seal failure. Over the generations, every Nissan Armada model has continued to use the same basic lip style Transfer Case Seal pressed into the housing, thus there are no design changes to compare, only gradual material updates. Fixing your integrity is straightforward but quite dirty business. Raise the SUV, unclip and label the driveshaft, pry out the old Transfer Case Seal from the bore, clean the bore, grease and evenly seat the new Transfer Case Seal, reconnect the shaft, and clip the clips. The factory fluid level is protected with prompt replacement to protect Nissan driveline components and help maintain the Armada's reputation for durability.

If you need any OEM Nissan Armada Transfer Case Seal, feel free to choose them out of our huge selection of genuine Nissan Armada Transfer Case Seal. All our parts are offered at unbeatable prices and are supported by the manufacturer's warranty. In addition, we offer quick shipping to have your parts delivered to your door step in a matter of days.
