Small update. I took a 4 hour road trip yesterday to Houston. I filled up before I left and then topped off on my way back home. My hand calced mpg was 13.1 !!! Now, I really can't stand when people get on vehicle forums and exaggerate mpgs, so I swear this is not that. I just think the tune-up I did a couple of weeks ago made a big difference.
So, next on the to-do list is the front end. I almost ALWAYS do my own work on my vehicles no matter what it is, but right now, I don't have a shop or a really good place to do front end work. I do know a very good mechanic shop that my FIL and wife's family has used for years. They quoted me $980 to do the entire front end with all new parts....tie rods, BJs, idler and pitman arm. I hate other people working on my truck, but it needs done and I am considering going this route. He did tell me they have doen quite a few OBS GM front ends and he is very acquainted with them. They want to use all Moog parts, but I think I want AC Delco. Opinions?
