ADVICE - Repair or Replace my '03 Tundra

Repair, and add upper and lower ball joints (OEM only). They are basically the only failure part on the suspension that you need to worry about.

 

Sounds like your leaning to Repair. Good decision. I sold my 2001 Tundra last year and upgraded to 2019 Tundra. Happy with my decision b/c I have kids now and needed more room for the family but my 2001 was running strong when it was sold and I still see it rolling around my town to the dude that purchased it. The engine you have is well know and legendary, even for Toyota.

I know all of this has been covered better than that i'm saying here; just wanted to add some personal testimony from my experience. I miss my 2001 for a bunch of reasons, it was the perfect size truck but family had to have more space.
