Sigh. Maybe. I like my guys a lot. Solid people. But maybe my rig is too much for them to take on at this time. Its certainly not the fun stuff like putting lift kits on.
Your guys can be good guys and bad diagnosticians, that's okay, and actually very common. They're probably very good and thorough when it comes to replacing or installing parts, and that's commendable, but what you need right now is a proper diagnosis. Best of luck.
