[DeTomaso] Oscillating vibration

[Dan Mixon]

I disassembled my half shafts a couple weeks ago. Apparently whoever had
assembled them last didn't know about the alignment arrows. One half shaft
was 90 degrees out and the other was one spline out. Never had any
vibration.

The halfshafts can be disassembled, by unthreading the collar in the center 
and separating the two halves.   They are 'clocked' and balanced, and there
are 
arrows stamped on each side to ensure that they go back together the same
way 
they came apart.   But the splines are universal, so you can accidently
clock 
them in any number of different ways.   If the U-joints aren't properly 
liined up with one another, it will create a horrendous vibration problem!

Mike (who sat for hours on the side of the road in rural England with George

Gordon-Smith and his Mangusta, waiting for a tow truck, after he picked it
up 
from a race shop that had tuned the suspension and accidently put the 
driveshafts together wrong, leading to horrendous vibration at certain road 
speeds....)
