I just replaced my shocks and springs in the front.  While apart, I decided
to replace the control arm bushings (upper and lower) and when I looked at
the ball joints, I found that both lowers had cracked boots and a bit of
play.  I went ahead and replaced all four (top and bottom).

My suspicion is that since the lowers require a lot more labor (and a
hydraulic press) they are not replaced during regular preventive maintenance
by typical owners.  As a result, they are subject to excessive wear once
they get to be the age of our Syncros.

Just a theory.
