Who's done them? Are they bad to do? I've done lots of ball joints but never on one of these.
I see just ball joints are available for the uppers, I remember looking at the front end when I bought it and thinking I would "have to" replace the whole control arm for just the ball joints but I looked them up and I see "just" ball joints available for top and bottom.

although i have never done a replacement on the particular vehicle you are asking about, it seems the quality of the bushings used in newer vehicles today almost dictate that when the ball joint wears out, the bushings need replaced at the same time or shortly thereafter.
with that said, it is almost always cheaper and quicker to replace the control arm [or both arms] than it is to just replace the bad ball joint, even spending more [hard earned] dollars to do so.
just my personal experience doing this stuff when required to do so.
your mileage will vary. especially if you need to purchase a ball joint removal/install tool and kit when you don't have or can borrow one, for a job you will only do once...........
[even using the "free loaner tool" most local parts stores have, you will usually find they have been used and abused [mostly abused !] by previous "customers", and won't work worth a hoot for you to get your new joint installed correctly.]

No I have the ball joints tools. Use them alot.as a fleet mechanic.
Just never done one of these particular trucks.
My work is in love with their Ford's.
Not me

And with bushings I've always replaced the bushing in the original control arm. Unless it's the type of control arm where the ball joints are integral and can't be changed seperate. That's the only time I ever replace a whole control arm.

Ok again I guess. I ask a question about how to do something and get crickets....
Something I'm sure others out there on a site dealing with the common brand, have dealt with...
It wasn't bad after I made the 70 mile round trip to work and back on a Saturday when I usually don't have to work, to get my ball joint press I have there as I have a partial set at home but not the adapters I needed. Yes it's possible to change just the upper ball joints without replacing the whole control arm. Something I try not to unless there's some kind of damage to that makes them unusable. I am glad they aren't like the Ford's I deal with at work, where they are integral with the control arm. And can't be replaced by themselves.
I know everyone these days wants the easy way out so they just buy the assembly whether it needs it or not.
Even on the 60s-70s cars I see all too often where people on all the forums want whole new (mostly Chinese) control arms for their projects. Rebuilding control arms is not that bad it's cheaper, and the parent metal on THE OE ones is better than aftermarket 9/10 of the time....
Hopefully this helps out somebody here in the future who runs into the need to do the same job.

Not sure what year you have but i have a 2nd gen 1500 and have replace the uppers/lowers with out issue i put a little anti-seize on the new ball joints threads for future replacements.

I resent the "gen" reference on Dodge trucks as Dodge made trucks way before what is known as "1st gen" but going by that crappy reference I think mine is "4th gen"
Before this one the "2nd gen" was the newest Dodge truck I had ever done ball joints in, and I used to do a bunch of them when I was an alignment guy.

I agree with you on the "Gen" crap. If you go be the different body changes, my 49 Dodge truck is like Gen 9 or 10. What some want to call a Gen 1 doesn't look anything like a 1917 Dodge truck.

Dodge trucks didn't have a problem with ball joints until the 1972 model year, before that it was usually "king pins" on the beam axles. The 72-93 truck's screw in upper ball joints were a challenge to remove and install. Most after 94 were press in, but some had clip retainers and some didn't. A lot of aftermarket ball joints added clips, rather or not the original ball joints had them or not, so before you start pressing them in, its a great idea to check for clips. I have seen several of the press in ball joints tack welded in after replacement. Bet those are fun to change. I have seen some the guy that replaced the ball joints wasn't happy just adding a few tack welds.

A welded in ball joint on a control arm with bad bushings and a bit of rust on the control arms themselves, are the reasons complete control arms became available. Usually, a ball joint press out kit works well, but a cheap set often doesn't have deep enough sleeves to get the Mopar Ball joints in or out, so you will need the proper sized and length of tubing to get the job done. I'm betting that promotes a lot of complete control arm replacements. The parts store you get the ball joint tool set from doesn't have the correct sleeve, so they can tell you it won't its too muck work to replace the joint, but they can sell you a complete arm for only this much more.

Got them done Saturday, yeah athe new ones came with snap rings .
I just don't agree with jumping to replacing the whole control arm when it's not necessary.
If they're not integrated, (one piece,) and there's no damage to the original control arm, and parts are available it's just stupid to replace the whole arm
And yeah I did a lot of the 72-93 style in cars and trucks.
I only ever had to weld them in one, and that was my dad's 86 B van. Back then if I wanted to change the whole thing the dealer or junkyard were the only choice.
I replaced control arms on a van one time at work (boss though it would be "easier" even though I was the one doing the job) and the aftermarket ones (weren't Moog, done there brand is never heard of to that point and from China) and they sucked.
I ended up getting just the ball joints and replacing them in the original arms and putting those back on. Problem solved.
