The only free moving parts in the torque tube is within the firewall/floor bracket.
Held between the two halves of that bracket is a steel collar which holds
a bronze split bearing p/n 702058-6. (part 31 in the picture shown on the forum
site) When the torque tube twists under loads exerted to the nose leg attached
to the torque tube yoke, the tube yoke section rotates within that bronze
bearing. Although the steel collar is held tight within the two halves of the
centre brackets, if the friction between the bearing and yoke become too tight,
there is nothing to stop that collar trying to rotate within the bracket which
may also cause squeaking. Why the parts book call out that p/n for the bearing
I dont know because it is not a replaceable/servicebale item. The only way
to replace it is to remove the torque tube from the plane and debond/unbolt the
end caps of the tube.
I assume by lubricating you may mean spraying so may be that has penetrated within
and between the bearing and tube and helped some what.
For pictures of a broken down split bearing follow the Read this topic online here
link below.

Here are some direct links to the bonded tubes if anyone still wants to look at
them (see the end of my message). I don't think broken bonds are the problem
though. I think it was just the bronze split bearing referenced by Ian. When
I lubricated that area with some light silicone lubricant, the squeaking went
away. I think some moisture had entered the area through a torn nose gear boot...I
flew the plane about six hours then it sat outside overnight in a rain
shower immediately before the squeaking started. The annual is about a month
away, so we'll be replacing the boot, and maybe adding some lubricant to that
bearing, although I'm not sure what the proper lubricant would be. I'd say
we're really just trying to prevent corrosion there more than lubricating. Would
something like LPS-3 be good for this?
Thanks again for the help everyone...this is a great list!

I'd like to meet the genius who designed, or, better yet, approved the
design of the roll servo mount. Or Both. Genius. Sheer Genius.
Forward Mount: The factory mounting holes are 3.6 inches apart. S-Tec
chose 3.5 inch spacing. So, the installer is either crowds out both
holes, drills both holes to 1/4 inch, or picks one and drills the other
to fit.
Aft Mount: The factory mount has 4 holes. The S-Tec mount has 4
holes. However, if you pick one, none of the other holes are in the
right place. If the installer picks the two most obvious holes and
crowds them out to fit, THEN, drills two new holes for the other two,
the two mounts are 1/10 of an inch too close together. If the other
two holes are picked, the mount is 3/8 inches to close together.
Truth is, the original mount 'could' be modified to use. S-Tec didn't
need redesign the whole mount.
Bottom line is, there is no way to make the installation clean.
