Hello, Dianna ... I'll second "4Crawler's" suggestion on this as it is pretty easy to do & if you managed to get those rear shocks off (did you???), you can definitely handle this tiny bit of maintenance up keep.
That is , unless it's a sealed unit, I'm not sure.

No way to service, just replace.

Cannister is sealed and filled with charcoal. Part of the fuel tank evaporative emissions control system. Fill gas tank w/ cold gas from underground tank, park truck in the hot sun, gas in tank expands and forces fumes out. Cannister is in the tank vent, charcoal absorbs the fumes. Then later when the engine is running, vacuum is pulled on the cannister to suck the fumes out into the intake, where they are burned.
To clean, pull cannister out, plug the Purge port and blow ~40 psi compressed air into the tank port, dust and dirt should flow out the vent port on the bottom.

How can you tell if one is "bad" or needs to be cleaned? Sould it part of a PM routine?
To be honest, I learned my truck has a new part today

Factory Service Manual will have the full test/clean instructions. On my '85, it says blow low pressure air into the tank port, make sure it flows out the purge and vent ports. Then blow into the purge port and no air should come out the other ports. Suppose you would see liquid come out if it was saturated. Cleaning might help.
