Front suspension some components are severely corroded

That is surface rust but it is pretty bad for a 3 year old truck. You must live where they salt the roads. Try washing the under carriage weekly in the winter.

I would remove and paint or powder coat the parts that come off easily. The rest I would look at coating with something to protect them, perhaps something like this. https://www.chemicalguys.com/barebones-undercarriage-spray/TVD_104.html? gclid=EAIaIQobChMI27bnqPzf4AIVdBh9Ch1jFwX8EAQYAyABEgKBK_D_BwE
