Quadra Trac input seal care
The input seal on a Quadra Trac transfer case keeps lubricant from escaping where the input shaft enters the housing. Because the transfer case sits low under the vehicle, leaks can collect on the underside and be mistaken for engine or transmission fluid. Wipe the area clean and check again after a short drive to see where the seep starts.
Replacing the seal means removing the input flange or yoke and cleaning the bore before the new seal goes in. Check the shaft surface for wear and rust, and use a seal driver that presses on the outer edge. Refill with the fluid the transfer case requires and check for leaks during the first few drives. Keep the vehicle supported safely throughout the job.
