Can't get my spare tire to drop down. My truck's a 2004 Sierra HD2500. The cable will lower all the way to the ground:money: but the tire only drops about 3". I've tried cranking it back up until it clicks a couple of times to no avail. I lower it and it sticks about 3" down. Part of the shaft that slides on the wire is stick in the housing. Dealer says to reef on it and it will come down..wrong- pulling down, using 2X4 as a lever wouldn't budge it. It's a good thing its not an emergency. I just want to clean the spare and undercoat under the bed. Whats the secret guys. Thanks Gregg.
