2012 isn't new by any means. It's a good idea to do all that at once anyway, if the vehicle has high enough miles and it needs it. I mean yer in there anyway touching those parts. How many miles??
You didn't mention upper ball joints?? Hard to imagine the lowers going bad and the uppers still good. Might as well change those too. ...or buy new Upper Control Arms, UCA's. While yer at it, probably should install new
anti-sway bar end link bushings (and maybe center bushings too). *Check* or inspect yer truck's
hub/bearing assemblies and
inner CV up/down freeplay at the diff (if 4x4). It would be a good idea to
check the trans/xfer case output shaft bushing for 'free play', and remove the rear driveshaft and
pop off the U-joint caps and inspect the trunions for grooving, etc (change that if it needs it). And insert some new grease (like grease) before you put the U-joint caps back on.
Use good quality parts or you might be doing it again in a couple yrs.
And because you live in MO, I'd
squirt some oil above the rear box wheel arches (better yet,
First clean all the crud out that gets above there, and wash/dry)...
and some oil in the: door bottoms, tailgate bottom, rocker/cab corners, etc so those areas don't rust out on you. Because they will. Probably not too far from now.
Oh, have your mechanic (or you can do),
flush out the old steering fluid that probably looks like crap, with new Mopar fluid, and
exchange the brake fluid with new. A little preventive work there can make a big difference and save you headaches down the road.
She'll drive like a dream when you get all those things fixed and be ready for another 10yrs!!
Note: **Don't** oil the door hinge bushings. Chrysler uses a crushed graphite bushing...lubricating just wears them out quickly (ask how I know!...).
