Just today this has started, but has been consistent all day. When I apply the brake, the Jeep will "clunk" when the speedo hits 30mph. It is not a audible type of clunk, more of a physical can-be-felt-by-every-passenger in the Jeep type of clunk. And it ONLY happens when braking, specifically at 30mph.
I've tried to replicate it when accelerating, gassing hard up to 30 to see if it will do it, but it does not. I've also tried NOT braking, just coasting down from 40 to 30 or less, and it does not do it then either. It only happens when braking, and exactly at 30mph.
I've searched thru several threads, but I'm not certain that I'm phrasing it properly to find relevant threads.
The Jeep is an 03 Sport, 4.0L I6, 76K miles, and Auto transmission. Any point in the right direction, or suggestions on what else I should check for along with the "clunk", would be greatly appreciated!!
Thank You All,
