I've got this annoying 'clunking' sound that seems to be coming from under the passenger side floor boards. Mostly when driving on bumpy or uneven surfaces. The shocks are all new and I've even climbed around underneath trying to muscle parts around to see if I could locate it, but still haven't. I'm thinking that it might be a bushing (primarily the one in the image below). If anyone has any other ideas, please share. Thanks!

 

if it was that radius arm bushing you should see it, try to tighten the nut?

how bout the swaybar? on some vehicles the frame bushings on the sway can be mega loud and they look fine

 

One thing to note; If you tighten the radius on one side you have to do it equally to both sides or your axle wont be equal distance to the rear, that will throw the axle alignment off.

 

Really sounds like shocks. Might have lost a rubber bushing.

 

Thanks guys! The shocks are all brand new and didn't resolve it. I'll torque down both equally and see what happens.

 

I had a horrible clunk from under the floor once. Turns out I left a full water bottle under the seat. Make sure it isn't something stupid like that.

 

I heard a kind of rustling noise that sounded like it was coming from inside the dash the other day - I think it was coolant. My system was low and it was gurgling. Probably not what yours is, but it came to mind.

 

Nothing under the seat or dash. It's definitely mechanical. Gonna tighten down those bushings tonight. Anyone happen to know offhand what size that nut is?

 

What about the front axle vibration damper (donut). Is it loose?
