GMC Truck owners- warning !
More GM innovative KRAP to deal with:
Does your truck have a spare tire SECONDARY LATCH SYSTEM in addition to the cable winch?
If so, you need to keep it maintained by spraying penetrating oil onto and into that latch box-along with forcing grease into it EVERY 6 MONTHS- or you'll find yourself on some lonely road with a flat and unable to remove the spare tire.
The latch system is open to dirt and road salt. It will quickly rust and will not release the tire when activated..
You can see the extent of the problem by just searching words: GMC ; truck ; secondary spare tire ; latch
and see what others say: @#@#%*
Of course, don't expect GM to slop a gob of grease on the unit as it leaves the factory. They need to keep their dealers' repair shops busy. Don't expect your tire dealer, who sees this problem regularly, to take a half minute to slop any oil or grease on it either .
