Left rear wheel won't spin
 

My '98 Dodge Grand Caravan LE left rear wheel drags for a few minutes while driving. When I have the van jacked up the wheel does not spin unless the lug nuts are loosened. The bearings check out to be fine, that is no noise when driving and no play in the hub. Hub spins very well. Braking seems to be fine. Caliper is not leaking.

It is possible that the line to the caliper is bad. This happened on my van. The brakes would apply fine, but would not disengage for a about 30secs after braking.

Try compressing the caliper with the line attached. If it goes easily it's not the case, if it is hard to compress, remove the line and try it again, if it then moves easily, the line is deteriorated inside and needs replacement.

Maybe the wheel is hitting the caliper and causing the problem. Tighten the wheel and turn the wheel and see if its hitting or maybe the pins holding the caliper.
