Glenn's response made sense to me, and I would point out that neither
of the frayed cable ends of the spare tire retainers displayed rust.
I'm in the midwest and we get our share of road salt.
Another thing worth noting is that I had removed another _intact_ one
from a junk caravan without first turning the nut to see if the cable
moved or not (never dreamed it wouldn't work--how often do they get
used?)... got it home and installed it and went to turn the nut to lower
down the cable and it did nothing either direction.
So I don't know if it has stripped gears inside or the cable is frozen
up somehow inside its housing.
In fact, I discovered the gears inside my original (frayed) one were
stripped, after I originally tried to just clamp a makeshift steel
bracket onto the end of the existing cable (above the frayed part) using
two cable clamps, and was just going to use it like that...and when I
put the end of the cable through the centerhole of the rim it would
crank up about halfway and wouldn't move anymore although the nut would
In any case, they must have their share of problems, for whatever
Grateful for your replies, as always.
