Hi people have a mazda 121 db (ei) 72ps bj93 150tkm have a problem the noise (appendix) first time coupling is new complete so durck plate disc and rear bearing when I press coupling noise completely away, when I let it come it starts, the higher the speed the louder. in the empty run you hear it loudest. the higher the passage the quieter when driving naturally. was today mazda workshop the thought immediately out back bearing, when I was just renewed (ca 5tkm) he actually said it must be possible to have material errors or something, if it’s not main bearing from the gear, but he was pretty sure to get back bearing costs 30€, but main bearing he meant with change a few hundred euros, because you get cheaper at ebay gears. hope you have a clue of what it can be thanks in advance At the sound file one hears only with then without a pierced clutch and then without and then driving off
