&nbsp;

You can hear the cracking sound from the joints when you move your body without warming-up.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

However once we start moving the body parts, the sound discontinues and the movement gets much smoother!

Check if any protective plastic

cover

or foreign substance is trapped where the louver or components are.
