Tech Note 1: 1999-2005
The Dana 50 Monobeam front axle was only used in 1999-2005 Ford full size 4x4s. It was the stock axle in F350 Single Rear Wheel and F250 Super Duty 4x4s from 1999 to early 2002 when it was replaced by a heavier Dana 60 axle. The Dana 50 monobeam was the ONLY axle used in the 2000-2005 Excursion. I have been unable to verify the Dana 50 being used in the Super Duty after 2002, but it is possible it may have been put in fleet, export, light-duty, or foreign assembled trucks.

Tech Note 2: Spline Size
Externally, the Model 50 Axle looks almost exactly like the Dana 60, however, the Dana 50 axle shaft splines and internal differential components are substantially smaller. If you are unsure which axle you have, you can call us with the axle tag number or check your inner axle shaft splines. Dana 50 inner axle shafts are 1-5/16" x 30 spline. Dana 60 inner axle shafts are 1-1/2" x 35 spline.

Tech Note 3: Dimensions
TK20369 is manufactured from a high-strength, chrome-moly, U.S. made forging. The splined inner end is approximately 1-5/16” diameter and it has 30 splines. The yoke end is made for standard Ford/Spicer 1480 series axle u-joints with 1-3/8" diameter cups. The span between the inner yoke ears is 3". Length from center of u-joint hole to end of spline is approximately 15-7/8".

Tech Note 4: 4x4 Tech Publications
An awful lot of axle shafts and new axle shaft universal joints are wrecked by slam-bang methods of service. Do it right the first time. See my Technical Service Bulletin TSB4610 Super Duty Front Axle Shaft Service or my Super Duty® and Excursion Front Axle Service Manuals TM4688 or TM4637.
