Door hanging

I having this prob and its really pissing me off. At first i didn't have a prob, but this guy who has a 74 came over while i was puting in my clutch and tock my door and wiggeled it up and down. Hes all u need some new door bearings. Now my door u sometimes have to pull it up for it to close. Also i don't know if that can also cause ur door locks to not unlock easily. U have to wiggle the key tell it grabs. it sucks :mad:
Let me know what u think. also any one know were i can get these bearings?

door hinges, or pin and bushing kit, can get at almost any parts store, don't think lock is related key or door cylinder is probably worn out.

Do u think Napa will have the bushing kit?
