After nearly a three-year hiatus, the Baja Bomber is back in action and ready for service as a desert racing support rig. But before we head south to chase Trophy Trucks through the silt of Mexico, we figured it would be a good idea to fortify our Dana 60 front axle. After all, nobody wants to deal with a broken front-end in a foreign country, especially where spare parts are scarce and vehicle abandonment usually results in a scavenger free-for-all. The last time the Baja Bomber graced these pages, we highlighted a custom-built aluminum flatbed designed to accommodate some very specific tasks associated with desert racing support scenarios.The last time the Baja Bomber graced these pages, we highlighted a custom-built aluminum f To complete this project, we turned to the very capable team of axle builders at Right Gear and Axle of Salinas, California. For over 15 years, Right Gear and Axle has been building high-end axle assemblies for everything from agricultural harvesting equipment to mud drag racers. Follow along as we address some of the weaker points of the Dana 60 front axle found in Dodge Ram 3/4- and 1-ton pickups built between 1994 and 2002. The first thing we wanted to address was the weakness of our factory Dana 60 housing. Unfortunately, Dodge used a central axle disconnect (CAD) setup on all second-generation 3/4- and 1-ton front Dana 60 axles. The arrangement consisted of a large cast-iron housing installed on the longer of the two axle tubes. This unit housed a vacuum-operated axle disconnect device designed to engage the front drive system whenever four-wheel drive was selected. While this setup is convenient for most drivers, it splits the long-side axleshaft and axle tube into two individual pieces-not a good thing for serious trail work. To fortify the weak area, we added a three-dimensional axle truss fabricated from laser-cut steel plate and tubing. This setup tied each portion of the axlehousing and CAD housing together for significant improvements in strength. This one-off axle truss was custom-built by a well-equipped fabrication shop and cost around $600 to complete. Once the truss was completed, the whole axle assembly was powdercoated to protect it from the corrosive saltwater common to Baja's low lying peninsula roadways. A set of 4.11:1 gears was added to the differential along with a master install kit from Precision Gear.A set of 4.11:1 gears was added to the differential along with a master install kit from P Here, you can see how the new ring gear was installed on the ARB Air Locker we already had in the front differential before we started this project. Notice how the wear pattern focused the tooth engagement in the middle of each tooth. This setup helps distribute the torque across the entire tooth rather than just the edges. This type of pattern is critical to long gear life.Here, you can see how the new ring gear was installed on the ARB Air Locker we already had With the new gear and used air locker installed properly, Right Gear and Axle's technician began assembling the new manual hub conversion from EMS Offroad.With the new gear and used air locker installed properly, Right Gear and Axle's technician EMS Offroad offers manual hub conversion kits for Ford, Chevy, and Dodge pickups. The parts eliminate the troublesome unit bearings and replace them with tried-and-true tapered roller bearings and Warn Premium lockout hubs. Additionally, the kit comes with stronger 4340 stub shafts for each side. The 4340 long axle shown here is also included to eliminate the CAD function of the axle. We like this setup because it offers significant improvements in strength over the factory two-piece axle design.EMS Offroad offers manual hub conversion kits for Ford, Chevy, and Dodge pickups. The part In addition to the EMS hub conversion kit, Right Gear and Axle added a pair of Mad 4WD inner axle seals to help keep contaminants out of the differential. These seals install inside the axle tube to provide an additional seal between the knuckle and differential. Each seal received a helping of high quality grease prior to installation.In addition to the EMS hub conversion kit, Right Gear and Axle added a pair of Mad 4WD inn To help preserve seal life, the new long-side axle was polished with a special high-grit sandpaper to create a smooth sealing surface for the Mad 4WD inner axle seal.To help preserve seal life, the new long-side axle was polished with a special high-grit s Here you can see the new stub axle mated to the factory short-side axleshaft. This inner axleshaft is the only axleshaft we reused for this project. This part is probably going to be the first part to break if we get into a bind on the trail. The nice part is that these shafts are inexpensive and easy to find at most wrecking yards. We like the idea of having a fuse in our drivetrain because it allows us to carry spare parts and all the necessary tools to fix a problem while traveling south of the border.Here you can see the new stub axle mated to the factory short-side axleshaft.
