SES is on. when coming to a stop I hear a clunk/thump noise.

What is your question?

The vibration starts when I'm driving 40mph for a while and I have no clue why I just got a new drive shaft, and mass air flow sensor. Had previous problems and got a tune up . 15 new hoses. New thermostat. New serpentine belt. Fuel flush. New oil seperator. New valve head gasket. After 6,000 put into my car my service engine soon just turned on after I got my driveshaft rebuilt with MAF. Any suggestions?
