yes, one of my manuals (spitfire 1500) mentions 'chalking' them before
disassembling to facilitate reassembly. I unfortunately read that AFTER
changing the u-joints... The joints made slight clicking noises for a couple
of days, I wasn't thinking of what it meant when it quit making the
clicking. The edges of the flanges were chipped off by then. There was also
a lopsided sort of vibration on one of the axle-shafts and a heavier
thumping sort of vibration on the main (prop) shaft. The vibrations went
away once I read about having to ensure the correct alignment and
reassembled them correctly.

Subject: drive shaft vibrations and ujoints TR250 TR6
My local non-LBC mechanic told me that I can risk the chance of drive
shaft vibrations if the drive shaft *flange* yokes are installed 180 out
of phase with respect to their original orientation.
I understood from Bentley and threads on this lists that the yoke halves
that are part of the drive shaft had to be at the same angle (the yokes
of both ends of the drive shaft had to be in the same plane), but I
never heard that one could not be 180 degrees off from it's original
orientation. I also never heard the flange end of the yokes could not be
reinstalled 180 degrees off with respect to their original orientation.
Any comments?
I'm concerned that I have already removed the u-joints from the IRS
axles and have lost track of the original orientation of the u-joint
yokes with respect to being 180 degrees one way or the other.
Any comments?
Did this make any sense?
