GMC 2008 Yukon Denali Clunk

To start off I have a thud/clunk when letting off gas and immediately going to hit the pedal again or taking a turn and hitting gas 9/10 it will thud and in the middle of slowing down whether or not I slow to a stop or use my brakes

So far I have repaired

  • motor mounts
  • trans mounts -greased slip yoke (felt slightly better after )

I planned on replacing these on next job to get rid of the clunk

-slip yoke -u joints -rear transmission seal ( efficient to replace while down there )

Was wondering if any of you have experienced this same issue and what the part failed for you whether it’s what I have listed or if it was something else I have seen that it could also be diff mounts but I’m not 100% I’m mostly googling and making educated guesses on what to have replaced
