OK so the denali is feeling great. I just got the truck a couple of months ago, when I test drove it I knew the suspension was done. the first thing I had to do was replace the hydro-boost unit since it was leaking. Well I guess the guy I bought it from didn't really tell me how long it had been leaking because when I reached out to him he told me that he would add about a quart of power steering fluid every three weeks and did so for about a year. That's when a lightbulb went on in my head, I ordered upper/lower control arms for the drivers side since those ones ad been covered in power steering fluid for about a year. Well low and behold the truck rides great. I ended up doing the passenger side also just so everything was new on both sides. The only thing I had left was the sloppy 4-ply tires so yesterday I had some nice 6-ply cooper discoverer at-3's put on it and it is even better. Friday I am taking it to my fathers garage and realigning it, probably add a little more positive camber to see if it gets better.
