Recently picked up a 2010. Swapped out the front rotors, pretty good shimmy to the old ones, though the seller said they were in spec. Once rotors start to shimmy they are toast. New driver front CV shaft, previous was a few months old but had a torn boot. Swapped in some used Gen 1 front shocks and springs. The truck came with Gen 2 shocks all the way around and Gen 1 coils on the front shocks. It rode horribly and was too high in the front, may be what ruined the newish CV shaft seal. It now rides so much better, like a raptor, not like a dang ol' work truck. Gonna do the rear shocks tomorrow.
The Gen 2 shocks are pretty new, so I will swap them on my 2018 when mine wear out.
