Rebuilding suspension. Where to start please!!!

[Professor]

Hello all. I've got an 05 4.4 (non sports ride) w/ 128k on the clock now. I have had a lot of creaking and popping when I take a turn or go over a bump. I've done some forum searching but came up with a lot of different things of what to replace.

My question is what kit is worth buying? I don't want to do anything made in China, but I do t want to spend big money either. I thinking in the $500 range. Is this doable with good parts? I looked at FCPeuro and ecstuning. Just not sure which kit to buy from either. Ecs seems to have there own kits at a significantly less price but I don't know the quality.

Any advice or direction is greatly appreciated!!!!
