I use to drive around and the smallest bump would create a thump sound similar to grabbing your tie rod and rotating it up and down with your hand. It is a very annoying sound. Well the other day I found this. A loose hose running across the front frame rail. It has a stock zip tie on it but looked as if it had slipped off the metal fitting. Well all I did was add some double sided adhesive where the metal to metal was contacting and two additional zip ties. Now my Jeep is running quiet again. I hope this helps others.:D

Middle zip tie was the original one. Right side zip tie is where the noise was coming from.

Good find, glad you eventually found it :)
