I have a 2007 Silverado 4x4 5.3 with 54k miles. Bought the truck in February with 44k on it (yes I drive a lot). As far as I know the only flush/fluid exchange aside from regular oil changes has been the front diff. Next week I am moving across the country, from NY to Montana and will have the truck fully loaded with my things. I just put new tires on, and am having brake pads replaced up front and again getting fresh oil. Of all the other possible things, what is most important right now? Tranny flush, injectors, drive line stuff? I am getting a lot of info from my service manager regarding the BG services. This is all new to me This Silverado is a whole different beast than my old vehicle and I want to stay on top of anything that may cause issue if ignored. The costs of these BG services are quite large, from experience, does anyone feel there is a major advantage in using them over say...my local midas or monro guys for the fluid exchanges? Aside from these...is there anything else I should checklist for the truck before heading out across the country? Thanks in advance, I appreciate it!
