F 250 Drivetrain Upgrade

Excerpt from Ford F250 Super Duty Drivetrain Upgrade - Putting Some New Guts in a HD Truck's Drivetrain: Rebuilding Our STD Instead Of Buying A New Truck
From the May, 2009 issue of Off-Road
By Jerrod Jones

But even with the advantage of the one-stop shopping at National Drivetrain, we still needed to visit our favorite drivetrain shop, South Bay Truck & 4x4 in Hawthorne, California, to get everything installed. National Drivetrain may be able to box up all the parts, but you cannot mail order all the knowledge, wisdom, and experience of a good drivetrain installation shop. It was a big job, but South Bay Truck had everything from National Drivetrain into our truck and ready to go in a day and a half.

  • F250 Super Duty Drivetrain Upgrade - Putting Some New Guts In A HD Truck's Drivetrain

  • With all the parts that National Drivetrain had sent us sitting on the bench, except for the driveshafts that showed up half a day later, we were ready to start tearing into our 1-ton work truck.

  • Frank Gilliland of South Bay Truck started tearing into the front axle. We had recently rebuilt the front hubs after an incident about eight months ago, but it was necessary to do again since we had to replace the ball joints and front differential.

  • With our front Dana 60 ARB locker, Motive gears, Spicer ball joints, and bearings installed, it was time to move on to the rear axle. South Bay Truck's Herrington popped off the differential cover while Gilliland removed the eight bolts from each full-floating axle shaft and pull them out so we could remove the differential.

  • Gilliland carefully installed the ARB locker into our factory Visteon 10.25 rear axle. ARB units are extremely reliable, but only if set up properly. Installation is everything with these lockers. An improper install will lead to air leaks and a locker that will not stay engaged. But luckily Gilliland is an old pro at these, and he was actually the first one to tell us years ago that any problem with an ARB was usually due to an error and installation.

  • When we said "increased capacity", we were certainly not overstating the case. Once the new pan was on, Frank Gilliland started pouring Ford automatic transmission fluid back in. If this was a factory pattern that we just put back on, Gilliland told us that we would likely need to pour four or five quarts. With the Mag-Hytec pan and place, we ended up pouring 15 quarts of fluid into the transmission! Now that is what we call increased capacity!

  • Once everything was buttoned up and put back together, we took the truck for a spin back to the office. It was like driving a brand-new truck! All the clunks were gone and the steering felt much tighter due to the new ball joints.Thanks to National Drivetrain and South Bay Truck, we were back in business with a well working heavy duty truck.Except ... if you can believe this, on the way back home we were rolling smoothly down the 405 freeway when the engine started to shutter before making a large bang and shutting down permanently. Oh gosh, what now?! Jeez, just when we thought we had this thing back to tip-top shape.... I guess we'll be making another trip out to Diesel Tech to see if he can salvage our Powerstroke 6.0L diesel engine.
