The GMC Yukon Transfer Case Seal is a tight barrier that ensures the gear lubricant stays inside the transfer case. This prevents detrimental leaks that may starve the gears and produce expensive damage. The Transfer Case Seal fits around the output shaft yoke, hugging the spinning metal while its flexible lip and spring keep the seal under constant pressure. This simple yet effective mechanism stops fluid escape even with high rotational loads. When the part grows older or the bushing that holds the shaft wears out, gaps form and fluid leaks onto the driveway, a sure sign that the Transfer Case Seal has gone bad. Owners can replace it by lifting the vehicle, removing the driveshaft, prying the worn ring free, cleaning the bore, greasing, and pushing a new Transfer Case Seal squarely into the housing before sliding the shaft back using the alignment marks. Across model years, GMC has maintained the same lip-style design since it is a good compromise between durability and affordability. Variations consist of small changes to the dimensions to match specific configurations of the Yukon driveline, and the part is applied equally reliably by every trim of the GMC Yukon. Ignoring a leaky Transfer Case Seal will rapidly cause the lubricant level to drop and will result in overheating of gears that need a full oil bath to cool and distribute torque evenly between axles.
