Getting a light thump on light acceleration

[bykr]

Seems to be a powertrain issue not suspension related coming from the mid to rear part of the car.Makes a light thump when taking off and occasionally when hitting a low speed sharp bump.Never makes the sound when at speed.Going to take it in soon to have the dealer take a look,any ideas? 2010 SHO

If it is powertrain related, either the support on the driveshaft is loose/worn, or the RDU needs fluid replacement.  IMHO.  Favoring the ds support at this point.

There are several TSB related to this. I believe the latest involves some valve body modifications and updated ECM program.

Thanks for the ideas guys.The Driveshaft support bearing sounds very likely-I'll have them take a look.

Would be the 1st I've heard of this. Find the TSB's this issue your experiencing is well documented
