Just a reminder that in the rust belt, the drop system for the spare tire system on Chevy trucks requires maintenance, especially if it’s equipped with a safety latch. There is a ton of You Tube videos showing rusted safety latches that cause problems hanging up while trying to drop tires. Annual lubrication is a good idea. Also, remember to mount the tire with the air valve to the bottom. We found my son’s 2010 Silverado was not equipped with a safety latch but we still had issues getting the bar in place to rotate the hoist mechanism. We used a scope beneath the truck to fiddle the bar into place. Good luck.
