To check ball joints is relatively easy. There is a load carrying ball joint and a pivot ball joint. The pivot joint gets minimal wear. To check the load ball joint, jack up the wheel to be checked. With about an 1" of clearance off the ground, place your hand on top of the tire and wityh a long sturdy bar under the tire, move the bar up and down. Feel for lateral movement at the wheel. you want to make sure that the wheel bearings are good and the movement is slight if any.

check all your fuses, there may also be a code about to set. the timeframe depends on your driving habits. or it could be the garage you are taking it to. ask them for a "drive cycle" printout. this is a form that explains the exact driving conditions for your vehicle to reset the monitors. you could also try taking it to autozone- they can tell you if it is ready or not.

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.

You will need roughly 5 drive cycles for the obd2 to allow you to pass emissions. If you have no other issues with the car I see no reason to get rid of it.
Here is a link of what constitutes a cycle.

Testimonial: "Thanks for the quick response!"
U have to operate the engine at all kinds of diff speeds and drive modes, it is called a OBDII drive cycle, here is how u do one.
1. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.
2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel trim and canister purge.
3. Hold at a steady state speed of 55 mph for three minutes.
OBDII monitors EGR, air pump, O2 sensors and canister purge.
4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions.
5. Accelerate back to 55 to 60 mph at half throttle. OBDII checks misfire, fuel trim and purge again.
6. Hold at a steady speed of 55 to 60 mph for five minutes.
OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.
7. Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge
