This parts search exercise that he performed for you is no small task. He's been a tremendous resource to me with my 2007 Yukon XL Denali.
I recently did a complete suspension rebuild on my truck, and I used all GM/AcDelco parts, except for the front springs which are Moog (GM no longer manufactures the front springs for my truck), and the compressor, which is Dorman.
I replaced the upper and lower control arms in the front, but did not change the trailing arms in the back. I replaced all components, as I did not know the previous owner's driving habits, and I was fortunate to have the needed cash available. However, as
@Doubeleive suggested you can limit the number of parts replaced, to be in balance with your own budget to complete the project.
I had a shop do the front with my purchased parts, as I don't have a large capacity spring compressor nor an alignment machine. I did the rear components myself.
I purchased all of my parts from Rock Auto, GMPartsDirect, and GMPartsGiant. My total freight costs were approximately 10% of the total parts costs.
If you have any questions regarding your project, let me know.
