Last night I tried to lower my spare so that I could access the wiring for the CHMSL feed for a cap. The tire would come down about 4 inches and then stop. The cable would unwind all the way to the ground. I pushed and pulled and was unable to get it to drop any further. Am I missing something here ? I froze my a$$ off laying on the ground trying to get this thing to come down, good thing I didnt have a flat and really need it !
