Vehicles of the Military: Rearend Replacement and Custom Fabrication

Posted by Currie Enterprises
Military vehicles and transports require more stringent standards because of their inhospitable and uncontrolled environments they often are subjected to.  Currie Enterprises has fullfilled the military's need for custom front and rear end axles and drivetrains. These include a vartiety of vehicles  (i.e. light armored vehicles, HUMVEE or High Mobility Multipurpose Wheeled Vehicle, Desert Patrol Vehicle, Light Strike Vehicle, Wiesel 1 7, M996 Mini-Ambulance, M997 Maxi-Ambulance, M1035 Soft-Top Ambulance, M1117 Armored Security Vehicle, Interim Fast Attack Vehicle, Gun Truck, LAV 600, ULTRA AP, Mine Protected RG-31, RG-33, Buffalo, Cougar, Casspir, International MaxxPr, BAE Caiman, Oshkosh M-ATV, M60A1 Armored Vehicle Launched Bridge, M88 Recovery Vehicle, M104 Wolverine, Grader, Wheel tractor-scraper, M816 Wrecker, Medium Tactical Vehicle Replacement, LARC-V, Heavy Equipment Transport System, M35 2-1/2 ton cargo truck, M939 Truck, M970, Family of Medium Tactical Vehicles, Heavy Expanded Mobility Tactical Truck, JERRVs, Logistics Vehicle System, Palletized Load System, Commercial Utility Cargo Vehicle, R-11 Refueler, and more)

For a custom or specialized rearend order please try and initially determine these three dimensions on your vehicle before calling a Currie Enterprises sales representative:

    1. The Overall Width (Dimension A above): The overall width can best be determined by putting the tires under the car (make sure to allow a minimum of one inch clearance for the fender and the frame rails) and measure the distance between the wheel mounting surface on each wheel.

    2. The Pinion Location: The pinion location in most cases will be centered; in some cases the housing is off center (a .94" pinion offset is typical, as in the diagram seen above). This allows clearance for brackets on very narrow rearends, so as to provide a platform for mounting upper control arm brackets for triangulated 4 link suspension.

    3. The Wheel Lug Bolt Pattern: The lug bolt pattern is the number of studs (usually 5) and the diameter of the circle on which they are placed. The diameter is determined by measuring from the center of the axle to the center of one stud and doubling the measurement. See dimension BC in the Axle Dimensions Diagram directly below.

To further assist you, below are listed the three generic housing end dimensions that Currie Enterprises uses in rebuilding and manufacturing its custom & specialized rearends. If you know your vehicle's housing end dimensions, this will also be most helpful to your Currie Enterprises sales representative.

Once you have determined the three dimensions listed above (and maybe more), please contact a Currie Enterprises sales representative at: (714) 528-6957 and have your information ready.

If you don't know exactly how to determine the dimensions listed above, then it would be a good idea to have the following information before calling a Currie Enterprises Sales Representative:

   1. Tire Diameter
   2. Horsepower
   3. RPM Range of CAM
   4. Type of Transmission
   5. Intended Use of the Vehicle

Thanks — we look forward to hearing from you!
