    Specs. When the underside of your Jeep Wrangler starts getting covered in oil, and you need to top up the transfer case frequently, it likely means that the seals in your NP231's rear extension housing have given out. Replacing these seals and the bushings inside the case can be done without breaking the housing. Omix-ADA's transfer case rear housing extension matches the stock part perfectly, and provides you with the part you need to complete the seal change and stop the gear oil from leaking out.

    Construction. Omix-ADA manufactures its transfer case rear housing extension out of aluminum, precisely like the original part. The part measure 6 inches by 4 inches by 4 inches and secured by 3 factory bolts. The inner bushing is also included, but not the seal. This component is rust-proof and lightweight, and is made to match stock fitment and performance. A 5 year limited warranty applies to this part, direct from the manufacturer.

    Application. Fits 1987-1995 Wrangler YJ models.

            Great fit

            Replaced due to the old one being worn out and not holding the yoke in place. No slop in there now.
