This problem is often addressed by adding copious grease inside the
housing 
to both fill the void-volume, preventing too much condensation from 
forming, and also by keeping the spacer/stud lubed up so condensation
doesn't 
attack the sensitive parts. 
 
The stock setup requires periodic hand-greasing of 
this area plus the bronze bushings at each end. No one does this.
 
>>The bushings are coated with some substance (teflon?) and look like
they are designed to operate dry. If the spacer rusts this is of course
not much good.
 
Gary Hall sells drilled studs with zerks that first delivers grease into
the space 
between the stud and spacer. Then grease migrates end-wise into the
pivot 
bushings at each end to keep them lubed as well. 
 
>>Grease applied that way will never reach any of the moving parts. The
ends of the spacer are shimmed tight to the end caps of the assembly.
When the end nuts are tightened there is no movement between stud and
spacer. The A-arm and stud/spacer also move as a unit. 

Drilling the upright for a zerk (or two) only fills the void volume, 
depending on the grease used to migrate to both the end bushings. 
 
>>This grease reaches the radial bushing movement and is actually useful
for lubrication.
