i have a very loud rattling noise that occurs when i hit a bump on 2003 Chevrolet Trailblazer

sounds like its coming from mid to rear of truck. rattles until i come to a full stop. it NEVER happens at idle. mostly after ive hit a bump in the road. its sooo loud and embarrassing. as i come to a stop it begins to sound like its winding out then will stop completely as i do.

Sounds to me as though you're in serious need of a brake job. Could liken the sound you're hearing to a huge spring getting compressed, then bammmmm... gives you the impression that its been released and continues to bounce all crazy at the wheels. Or tie rods n ball joints. hard to tell at the keyboard.

May the wind always be at your back. May the sun shine warm upon your face, and rains fall soft upon your fields.

Sounds like your sway bar end links. Mine went out and this caused the exact same sounds on my 03 TB.
