The other item that may be causing trouble is the electrical contact between the rotor and the capacitor frame. Sometimes a drop of oil in the bearing and/or on the rear point of rotation will clean the contact and get rid of the popping sound.
Some variable caps have "wipers" that do the job of maintaining the electrical contact. They can also benefit from both cleaning and lubing.
