Wanted to post up for all those wanting more steering on a budget. This is fairly simple way to put XR10 universal shafts into your AX10 axles, and get the benefits of the 8* kingpins and adjustable caster.
First you will need these CreationFab Delrin Tubes:
http://www.rccrawler.com/forum/axles-trannys-t-case/374227-creationfab-delrin-ax10-tubes.html
A local guy was nice enough to lend me his sportsman truck to test these tubes on, and do an install to post pics for an instructional post. Time was limited, so you don't get any fancy pics, but some on my dinner table pics:mrgreen:
I would like to note that I put about an hour on the truck and gave it a really good beating. None of the screws came lose. I am using plastic knuckles and chubs as well as a piano wire tie rod. So there is a little flex in the steering, but I don't think that effected weather or not the hardware kept the tubes secured.
The truck started with stock dog bones. He has struggled with turning in our local novice class. So I offered him some free and/or cheap parts in exchange.
These are the parts and tools required to do this procedure. I forgot to picture my fancy hi-tech vice grips.
Parts:
-Axial XR10 universals(Part # AXI30563)
-Knuckles and Chubs of your choice. I HIGHLY recommend Vanquish chubs and Vanquish Wraith knuckles
-CreationFab Delrin tubes
-New tie rod and drag link
-x8 3x6 button head screws to mount tubes firmly into housing
Tools/Other:
-Drill
-#40 bit
-Something to cut the stock tabs off(I used my band saw and bench sander) Dremmel or xacto knife will work too
-Common hand tools to dis-assemble your truck
-Something to measure the angle of your caster. Non-matched caster might result in goofy steering. I used the angle finder pictured
-Vice grip pliers or something to clamp the 2 halves of the housing together.
-RED LOCKTITE
First thing I did was take out the front axle. Then I took off the stock knuckles, chubs, and axle shafts. Once that was done, I cut off the stock chub mounting tab FLUSH at the edge of larger part of the housing as pictured below. I rough cut it on my band saw, then sanded it flush on my bench sander.
Now, I didn't take apart the 2 halves, or take out the ring and pinion because I didn't feel it necessary. Although you will get plastic shavings in there, and it wouldn't be a bad idea to take it all apart and clean out all the crap before the final re-assembly.
Now, I mounted the chubs onto the tubes.
With the tubes and chubs mated, and the axle housing trimmed, it was time to slide the tube into the housing. I slid it in as far as it could go. It took me a while to figure out a good way to measure caster OFF the truck. But I figured out that the 3 mounting pegs for the servo were all level. So I flipped it upside down, and then measured the caster that way with my angle finder. Once it was set I clamped the housing to the tube so it wouldn't move on me while drilling the holes for the hardware.
Started with drilling and installing the 2 inner most front screws as seen in the 3rd pic down. Then I drilled and installed the inner 2 screws on the back half of the housing as seen in the 4th pic down. With those both firmly secured, clamped the ends of the housing. Then I drilled out the tube where the 2 screws on the top go in for option parts as seen in the 5th pic. I did this procedure last because I didn't want to risk the drill bit making the caster move while drilling the pilot holes.
This is what you end up with.
New drag link and tie rod made up. Steering as you can see is respectable for a sportsman. I used 2 stock XR arms for the steering arms because they are 0 ackerman angle, and were accessible.

PLEASE NOTE:
Do not tap the holes. Running the screws directly into the plastic ensures a tighter fit. Also, use a generous amount of Red Locktite. Let that sit overnight for maximum hold.
