100.000 km problems solutions part iii -1

[BOTONOSI]

3rd problem : From 90.000 km I was feeling and hearing a metallic noise for a while when I was accelerating hard and suddenly from 0 km/h .After initial acceleration didn’t have any problem or noises There is a relative topic in this forum written from me asking for any help from any of you.This noise was getting more annoying and stronger from 90.000 to 100.000. Note : This noise didn’t have any effect on reducing acceleration of the car.Just this annoing noise.
continuing with solution...

That noise may be a catalytic converter letting loose internally.

This is maybe completely off but before I change my brakes I always noticed a grinding from the rear and thought it was the old brakes or rotors. After new brakes I still heard the noise, it was not rattling just a light clanging and a strange grinding from the rear, very difficult to pinpoint. My mechanic took it to the shop and they found out that one of the drive axles was gone, no leaking or other damage visible.
