installed 2 days ago. might be one of the easiest jobs to do on the these trucks, to swap UCA's. my original bushings and BJs were in pretty good shape for a 227k truck. could have gone another 10k or so. anywhooo...the results! had it aligned yesterday. mechanic was as nice and knowledgeable as could be. invited me to watch the whole thing from next to the computer. i think he understood that i knew my way around the truck. though the initial numbers are close, the last alignment that was done by the PO could not get the caster to any better than 0, so in installing the new UCAs and not hitting my matchmarks exactly, those are the initial numbers yesterday, which were pretty damn close to what he dialed in. the truck also pulled to the left "pretty good" as he put it. did it before and after a tire rotation. he swapped front tires left for right. he believes it is a bad tire that is pushing or pulling. so there is some overcorrection for that. i have KO2's that have 30k on them. he also set the alignment for the greater than typical crown/grade of the roads around here so it doesnt want to wander down to the curb.
bottom line is the truck feels much more planted, a bit tighter. easier to drive. have not been on the highway yet. im hoping more than anything that the decent wobble of the whole truck at +75mph will be gone.
