[DeTomaso] Parts for Rear Uprights

[John Taphorn]

I agree with Dennis.  The drilled shafts are a poor design as the grease 
will not easily migrate to the exterior of the larger long sleeve that the 
drilled shaft slides through.  As a consequence, through condensation or 
splash, water can still form in the space between the hub carrier, bushings 
and the longer sleeve leading to corrosion and freezing up.  I've worked on 
many cars where the shaft slid out easily from the sleeve, while the sleeve 
was married to the bushings and carrier.

A singe zerk in the hub carrier is the superior solution.  It fills the 
space on the back side of the sleeve displacing air with grease and assuming 
the sleeve is drilled, lubricates the shaft and eventually gets squeezed out 
by the shaft's ends.

If you lack this zerk, be sure to add it. Or the job is incomplete.
