What is the bottle behind spare tire?
I replaced rear shocks yesterday and discovered a small cylinder container behind the spare tire. What is it?
While under there, I took a good look at my spare tire. The tire and wheel look fine, but the mount and screw holding it up is fully corroded. For sure if I had a flat no way could I get that wheel off on the side of the road. I've known it was a problem but since I don't venture far from the house, didn't worry much about. But now we need to take the truck on occassion to deliver furniture to our sons in college so I want to make sure I can get at the wheel in case there is a problem when traveling (especially since my wife will be with me!). I figure I just replace all the mounting pieces and get the parts from the dealer. Any other suggestions from anyone?
Thanks, Pat

It would be a good place to conceal contraband.

The cannister is for storing fuel vapors (i.e., "unburned hydrocarbons") that escape from the fuel system. Inside the the cannister is a charcoal element. When the time is right (usually warm cruise), the PCM commands open the purge flow valve and the vapors are drawn out of the cannister and flow into the upper intake manifold (via vacuum) to be mixed in with the a/f charge and burned in the combustion chambers. It only gets maintenance if it leaks.

pgw85706, your comments about the spare tire reminded me of some conversations last year, on this forum about just such a topic. https://www.ford-trucks.com/forums/5...pare-tire.html
Maybe a good antisieze compound on the moving parts, or periodically spraying them with something like WD-40 or one of CRC's products, or even white lithium grease, would be helpful in cutting down on corrosion.
If replacement parts bcome an issue, maybe a salvage yard would be worth a look, but if your in the rust belt, those parts are likely to be about as bad.

I just keep mine in the bed. After sawing/breaking the mounting hardware to get the spare out from under the bed I decided it was better to sacrifice the space than lie in the slush on the roadside trying to get that thing out from under the truck. Did come up with an inexpensive way to hold the spare against the edge of the bed with 2 eye bolts and an EMT hanger that minimizes it's footprint in the bed.
