Kid in a candy shop!
Curious if you replace front control arms and drive shafts as part of preventative maintenance?
Drive shaft ujoints for front and rear— yes.
Front upper and lower control arms will most likely be replaced in phase 2. Not due to PM per se, but I prefer to make a new-to-me-truck “mine” in terms of operating systems. That way I’m never second guessing the veracity of the work done on the truck.
I did it using the best parts available.
