Always checking them is a good idea. However, I found that if you out a dab of blue Lock-Tite or silicone(does the same thing), you have a very low chance of those bolts coming loose.
On bolts that are seeing constant vibration and movement, this is definitely a good idea. Lower ball joints, upper ball joints, the four bolts that hold the lower control arm to the spindle.
Honestly, if you torque them to the correct specs, the chances of them coming loose are slim to none, unless you just installed something and it needs to settle. Then, checking them would be necessary.
Add some BLUE(that way you can still get them off if needed, he red will never let go) Lock-Tite or silicone and you'll be good to go.
