Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Incredibly violent banging under hard acceleratio?

Hi all,

(New here but loving this forum)

Driving my new M3W today on its first drive (with the exception of taking it home last week) and at one point I put the pedal hard down. I immediately felt a violent and very loud BANG-BANG-BANG. It sounded very destructive and I was sure the driveshaft had come loose or something. It does it in lower gears, the lower the gear the more violent it is. It sounds and feels like someone is hitting the underside of the car with the sledge hammer. Feels like it’s coming from the tunnel area. Anything up to about 75% throttle the car is fine though.

I can’t for the life of me work out what could cause this (I’ve built cars from scratch but the M3W certainly has some bits I’m not familiar with!). I’ve not found anything searching. Has anyone seen this issue before?

Thanks,

Greg
