Sa akin naman pag biglang release ang clutch sa 1st and 2nd gear meron akong marinig na "bog" sound,pero kung releasing the clutch slowly wla akong marinig. i went to mitsu davao and tagum.they drove and checked my strada(2013 4x4)but according to them its normal since meron clearnce ang differential na up to 5cm ,mine is only 2.4cm(differential backlash).
