I'm taking another chance with Dan, I'll see how it works out. I was a little bothered by the wide track of my ERBE with those LST XXL shafts so I decided to see what I could do to bring the track back to normal. It was simple enough, the axles of the shafts are hardened steel but not quite hard enough to keep from using ordinary drill bits on them. I made new 3 mm holes to reposition the hexes where I wanted them and used an ordinary but good quality M5 tap to make deeper threads inside the axles for the grub screw to go further in.

Here's the new hole. I measured the center of the hole to be 19.5 mm from the tip of the axle.

Installed on a spare RD Racing axle carrier with a thick aluminum shim that is used on the pinion of an LST XXL diff.

So I don't have to measure each time to drill the holes, I made a jig from a scrap piece of metal. The axle slips into it and I just have to insert the drill bit in the correct hole. This block of metal was used for many other projects as a jig so that's why there are many holes in it.

I now have LST shafts on with the correct track width on the truck.

Now this is cool, I just modified a stock axle carrier to accept a 15X21 inner bearing and a 8X16 outer bearing so the LST XXL shafts could be used with the stock axle carriers. The 15X21 bearing presses right in using a 5/8'' socket and a vise. The opening for the outer bearing has to be enlarged to accept the 8X16 bearing. This brings the total cost of parts needed way down. I'll post pics this weekend.

I made a mistake when I listed the materials for this mod, I wrote that the outer bearing was 8X15 but it is really 8X16.

Pressing the 15X21 inner bearing in the axle carrier.

The outer bearing opening was enlarged just enough so that the outer 8X16 bearing could be pressed in also. This makes both bearings nice and snug with no play.

A full set of stock axle carriers with LST XXL CVD shafts ready for use. This took me just under 40 minutes to make.
