As everyone knows, I was having issues with my steering on the super. Knowing that I have been going over every piece of the steering mechanism to see where it can be improved.
Here is something I did that makes a huge improvement on it.
TXT Knuckles are attached to the axles by shoulder screws that screw through the Axle C to the knuckle. This causes slight binding especially when the hole starts to hollow out. You get a lot of slop.
A couple of things you will need...
Dremel or file
Drill with a 5/16" Bit
(8) 5 x 8 Flanged Bearings
Exacto Knife
Threadloc
First thing is you need to disassemble the knuckles from the axles. Make sure you don't lose the small washer between the C and the knuckle.
Now take the drill and slowly drill as straight as possible, the existing hole to a 5/16". You can step this up to the final size to minimize cracking the axle case.
There will be some remnants of the raised part of the old hole there. Use an exacto or some other sharp object to trim it off flush with the main surface of the C.
Now with a dremel, file down the bottom edge of the shoulder, there is an edge there. Don't remove a lot. You could probably accomplish it with some sandpaper. Test fit the screw in the bearing. Do not force them.
Next, Press the bearing in from the outside in. Just use your finger pressure and make sure it is flush. It should be tight. After that, replace the knuckle and proceed to screw the shoulder screw back in. Do it slowly to make sure that the doesn't bind.
I would recommend threadloc if you are using aluminum knuckles.
And here is the final product..
The steering turns much smoother and you don't have to worry about binding or any sloppy steering.
Good Luck

I know of a TXT that needs this treatment.
