When jacked up, should my wheel spin freely?
Greetings,
While jacked up to swap wheels get an alignment. I noticed when I tried to spin a wheel, it was hard to turn. Not two hands hard but it would NOT continue to move at all when I let go. No freewheel or spin was possible. This was a front wheel but I may have tried it on a rear as well.
i thought this could be a cause for my horrible gas mileage.
Should my wheels be able to spin freely at all after i let go?

They should spin fairly free. At least one or two rotations before stopping, maybe more depending on how hard you spin it. It could be a caliper locking up. Jack up the whole front end and compare both front wheels for resistance. Also check brake pad wear from side to side. It will kill your gas mileage.

there should be some bearing drag when you spin the wheels.1 to 2 rotations at most when spun by hand as chiken said.
If your calipers are dragging badly, you can hear the pads scraping against the rotor, however, pads are designed to lightly drag on the rotors at all times. This is to keep the rotor surface clear of water when driving in the rain. There are flat springs that do this.

Another common source of stuck calipers are seized caliper bolts/pins, which you will want to check for before replacing the whole assembly. The rubber boot that keeps the grease packing on the sliding pins deteriorates over time allowing the grease to dry out and the pins to start rusting which prevents the caliper from sliding freely. It's a cheap fix if that is the problem. Just remove the pins and if they're not bent, clean them off of all the rust, regrease, replace the rubber boots, and reinstall them.
