Developed a clatter what could it be

I have had my 06 Liberty CRD since new. :JEEPIN:

It has developed a clatter that sounds like a diesel clatter you expect to hear when it is very cold. This clatter begins when slowing down from about 20 mph until stopped. Once the truck is stopped the clatter stops. If I rev the engine while stopped the clatter will not restart. This makes it very hard to diagnose or discover the source of the clatter since it only happens when slowing down. :furious:

It is also impossible to tell if it is coming more from the right or left :banghead:

My current theory is it could be the motor mounts. Anybody out there think I'm right? What else coud it be? :ALONE:

Next time you're stopped - switch from drive to neural to reverse
listen for the noise and see if it's there..

motor mounts rattle - but the stress changes forward to reverse.

Another possibility is the vacuum pump or a line leaking. You're putting more load on it when you hit the brakes and it gets noisier- at least mine does. It only happens for me when I am towing a trailer and stopping a little fast.

What's the sound like when you coast to a stop without applying the brakes?
What the sound like when you go over a speed bump?

I had one of the motor mounts replaced on mine at the stealership for like $400. The CRD would have a slight knock at idle and would have a very rough shut down (shaking and knock). The MM repl. seemed to fix the problem. Good Luck.
