      Specs. One of the possible causes of oil leaks from the transfer case is a broken or worn out selector shaft O-ring. Though the cause of transfer case oil leaks is more often a poor seal around the output shaft, this O-ring can also be the source. If you pinpoint the oil leak to this place, you can use Omix-ADA's Selector Shaft O-Ring for the NP231 Transfer Case to substitute exactly for the OE component, stopping the leak and keeping your Wrangler running longer and better.

      Construction. The Selector Shaft O-Ring for the NP231 Transfer Case by Omix-ADA is a replacement part designed to exactly match the measurements, characteristics, and performance of the original O-ring. Made out of composite rubber, this part is an excellent quality replacement for all rebuild and repair jobs on the NP231 Transfer Case. The part comes with a 5 year limited warranty against defects in materials and workmanship from the manufacturer.

      Application. Fits 1987-2006 Wrangler YJ and TJ models.
