This is a new very correct and very high quality front output yolk. This is for the the Dana 18 transfer case. These are bad about grooving out on the seal sleeve and will leak gear dope. If you have replaced your seal and it still leaks it is the yolk that is worn out. This is a high quality reproduction and has the dust shield and felt already installed. This will fit the original transfer case in the MB, GPW, CJ2A, CJ3A, CJ3B, M38, M38A1, early CJ5, and M170. Yes this comes with the dust shield as shown in the picture. These are 10 spline.
