halfshaft phase???
greetings,
we are replacing halfshaft u joints in a '65. we checked in with the 1963 shop manual for refresher info and came across the following statement on page 4-17; ' rotate yolks so that trunion seats are phased 90 degrees apart'. that statement sailed right over my head. can someone please clarify ? I see only one way to install.
thnx.

That is wierd. The only way I have ever heard of "phasing" is on a driveshft where one end can be removed. With the haftsafts being one piece there is no way to change the phase.

I looked up that passage in the shop manual. It is in reference to installation of the half shaft. What it is saying is insert the inboard u-joint and install the u-bolts, then turn the outer u-joint saddle (trunion) so that it is 90* from the inner u-joint saddle. You have to do this to install the half shaft because the u-joints themselves are installed at 90* angles to each other on the half shaft.
Basically they are just stating the obvious but saying it in a way that is is somewhat confusing. If the outer saddle wasn't phased 90* from the inner saddle you wouldn't be able to install the half shaft because the outer u-joint wouldn't line up with its saddle.
