2008 Silverado 2wd shuttering Grinding noise coming to a stop

[greglowe]

I've been chasing this for weeks but, when driving and coming to a stop I get a grinding /chatter right before coming to a complete stop , sounds like really bad brake pads,or slight abs engagement.

I've Check front Brake and calipers, Rear Shoes and drums front hub bearings for play .

one other observation I've noticed it more if the engine is in 4cylinder AFM mode. If I put the truck in Drive3 to keep it in V8 mode its a very hard to notice but its still there but not as noticable

I also hear something that sound loose under the truck when it happens and I feel a sensation in the gas & brake pedal

no codes present
