O.K. Gang.
As promised, here's the guide for converting the steering and the rocker arms on you xk98 and up, as well as you touring (not sure which model is the first compatible), to full ball bearing.
What you'll need:
A 6mm drill bit with a drill, preferably mounted on a stand or with a very steady hand, as the holes need to be drilled accurately
3X6 flanged bearing - 6 pieces
8X4 bearing - 2 pieces (comes with the original kit)
4X3 metal tube - 6.3mm length - 2 pieces, Comes with the original kit, but can also be found on Tamiya cars, shouldn't be too hard to find in hardware stores either.
some motor shims with 3mm inner hole diameterM3 shims - 2 pieces.
First lets start with the rockers.First thing you'll need to do is to enlarge the hole in the rocker to a 6mm diameter. Be very careful to drill it straight so you don't bind the suspension later.
Next, insert a 3X6 flanged bearing into each side of the rocker, slide the rocker over it's pivot, slide a thin motor armature shim above the outer bearing and tighten the nut.
The pic below shows the order of the parts...
Congratulations, you've got BB rockers
-----------------------------------------------------------------------
Now lets move on to the steering which is a bit more tricky.
First thing you need to do is to remove the "shoulder" on the gearbox cover, next to the crash pin.
Here's a pic
WITHthe shoulder...
And here's one
WITHOUT the shoulder and drilled to the correct diameter (6mm)...
Next you need to drill the top hole on the gearbox cover, to a 6mm diameter. Again, make sure it's the
TOP hole and again make sure you drill it straight.
Now lets assamble the steering
Here's the layout of the parts:
Insert the 8X4 bearings into the bottom holes on the gear box covers...
Insert the 6X3 Flanged bearings into the top holes on the gearbox cover...
Insert the 4X3 metal tubes into the bottom bearings (As the size is very important, you might have to modify them a little. What you want to achieve is the 6X3 flanged bearings to sit in place while the tube is protruding just a little out of those bottom bearings...
now slide your m3 screw into the steering arm, place an M3 washer on the other side, and run it thru the tube ...
*Slide a motor armature shim over the top of the screw and secure you nut
Congratulations, you now have BB steering in your Pred
Hope you guys find it useful ...

* The reason for the armature shims below the the locknuts is to prevent the nuts from apllaying preasure on the whole bearing thus allowing the bearings to work freely while the nut is tightend.
You might need more then one shim or something a little thicker, any way just experiment with it untill you get it to work just as good as it works on the X10 ;D
