So every time I roll over a little bump or crack in the road I hear something from the rear suspension, sounds like something is loose. I checked everything all tight. Could be my springs, isolater is in place. Im stumped, its really annoying.

 

Perhaps a bushing. See 2004 Land Rover Discovery Suspension Bushing at CARiD.com

Would be hard to eval on the ground, up on a lift may reveal more.

 

I was chasing this same noise and it seems to be my drag link. If I rap on the link while parked it I can replicate the sound. Looks like it is coming from the threaded section with the clamps. I am going to try and tighten the two clamps. Mine also looks a tad tweaked.

 

Can you hear it if you manually rock the truck, while standing at rear wheel?

 

Did you check the watts linkage? Lucky8 has a viedo on YouTube on how to check it.
Push, side to side, on the rear of the body.

 

I'm with acamato on this, sounds like watts linkage. Does it happen when you back over a bump usually? Here's justin from L8's video on it.

 

Me 2 that's why I asked about rocking it

 

Watts linkage or warn shock bushings. Both easy to fix or replace.

 

Must be watts. It makes sound when just turning sometimes.

 

What do I do to the watts
