Front End clunk???

Hey guys is there a step by step to test/track down front end noise?

Here is what I have replaced in the past 3 months:
New Drag Link (both ends)
New Track Bar
New sway bar links
New Shocks
New Hubs both sides
New Upper and lower ball joints

All of the above got rid of 60% of the noise, but I am still hearing a knock when I turn left or right or go around a curve left or right....I have read every thread and cant seem to find a checklist for diagnosing clunks.....

Last night I had my wife turn the wheel while I laid under the front end but the engine noise made it impossible to find the noise.

I'm pretty much in the same boat as you.
Replaced all but the shocks. I'm beginning to think it's just all the suspension and body bushings.

Loose track bar bolt? It is susposed to be 410lb of torque I think. Just a thought that's what was clunking on my truck.

176000.00 rarly use 4wheel drive. When I did the ball joints and HUBs the ujoints seemed good, but that was just from handling them when I pulled them out on the shaft.

I use a small prybar inside the joint and apply a little pressure while looking for movement. This wont help with a tight rusted up one but if you have a clunk then I doubt that part is tight! Lol
