2000 rpm Rear bang on c43 amg
Hello everyone, so two days ago I had taken my car to the shop and lifted it on a hoist for a nice check up. I asked my mechanic couple of question if it's okay that the diff is sweating and drips a little oil he said it was normal. I also asked him if the tranny mount was worn out and he said it's a little loose but not worn out. He also checked the flex disk and it looked fine. Today I started noticing some sort of bang when going from 15-20mph. Whether I let go of the accelerator or press it I felt some movement and a loud thud noise in the rear.

We did a visual inspection on the flex disk and there were light cracks on the flex disk. I asked him do you honestly think this is okay? He said yes you should be fine. I bet the inside of the flex disk is toast. I had a feeling it could probably be it. When we checked the tranny mount he used a plie bar and jiggled the transmisson a little. He said oh its okay that's normal for a 16 year old car. I don't know well thanks for letting me know man. I will put the tranny mount and flex disks on my to do list lol. I probably have to change the seals on the diff I can smell oil when I open the trunk.

Open the wallet. If a visual brings up cracks etc on the flex disks, they should be changed. I hope your drive shaft doesn't fall off when driving, that can be very nasty. In all cases, you need to get the car on the hoist and a have a very close at things.

I would add that if your technician says everything is fine, change workshop. A sudden bang is nothing you should ignore, not unless you drove over a policeman...
