Front End Creaking Noise

70 Duster with Dr Diff spindles & new lower ball joints. QA1 UCA & LCA and K-Frame. PST adjustable strut bars. New tie rods, idler, & pitman arms. I upgraded the entire front end at once but there was no noise before doing so.

I get a creaking sound especially when going over bumps and using the brakes. Here is what I've done to try to isolate the problem:

- Removed shocks & sway bar & drove car. No change in sound.
- Installed different disc calipers & pads (to verify it is not just the pads rattling)
- Visually inspected the frame & UCA mounting areas for cracks that may be causing the noise
- The LCA rubber bushings look to be intact

I'm at a loss here.
