XJ6/XJ-S DRIVELINE U-JOINT REPLACMENT

[Dan Jensen <Dan.Jensen@GAT.COM>]

One note of caution when replacing the drive (propeller) shaft U-joints,
center bushing, etc. on the XJ6 and XJ-S. It is a split shaft that is
balanced with the halves together. Be certain to mark the relative location
of all components: front and back halves of forward shaft (the half with the
splines), and forward shaft-to-rear shaft). I would use a metal punch or
marking paint. I did not do this before replacing the driveshaft center
support bearing on one occasion in the past and did not assemble them in the
balanced condition. When accelerating from a dead stop, it practically shook
my teeth out. I was able to put the pieces back approximately as balanced by
the factory, but it has retained a small vibration to this day. I have not
bothered to have it rebalanced, but it is a minor irritant that I could have
easily avoided.
