A few of the studs on my truck have pretty rough threads, some lugs took almost a minute for my Milwaukee impact wrench to bust completely off (normally takes 10 seconds, if that.)
Should I chase the threads? Or replace the studs? I've never replaced them on a vehicle before. On these trucks can it be done with the hubs still on the axles? Both my 10.25 rear and D60 have rough studs in a few spots.
I'm buying new lug nuts all around. I think the PO always used an impact and just torqued the lug nuts too much.
If they are that rough, when you chase them and clean up the threads there might not be enough thread left to be safe. Chase a few and inspect them VERY closely. Don't take a chance!

I don't have a chase or die set, so I'd be putting out money either way. Not looking forward to pulling off hubs to do this, was hoping if I had to replace studs it could be done in vehicle.
I've pounded out the rears, with the axle on, and replaced them after pulling them on with lug nuts with spacers to draw them up. Front rotors have to be pulled to replace them.
Most affordable sets won't have a 9/16 fine thread die; they usually stop at 1/2". It would be best to buy them as they are need for sizes bigger than 1/2".
Not to be picky (well..) technically there are taps and dies for cutting new threads, tho actually a different tool is used for "chasing" threads?
What would be the correct tool to use in this situation, a thread chaser, correct?

Thread dies and chasers are a bit different. I just bought the Lang 7 piece set on Amazon for $32. Specifically made for chasing hardened lug studs. Same exact set Lang makes for Snap-On
If you've never used thread chasers before, don't forget to back it off a quarter turn or so for every few quarter turns of forward resistance.
And a drop or two of lube probably won't do ya wrong.
Since the thread is here I would like to know how you make out, and if you have to go ahead and replace a few of the worse studs when you're all wrapped up...

IIRC $50ish on eBay will get you a set of coarse and fine taps and dies through about 1". The wrenches are crap but the taps and dies are what really matter.
I'm sure someone who's trying to not feel ripped off for spending $1000s on Strap-On tools will complain that the eBay and flea-market junk is made in China but they work fine for chasing threads and work fine in softer steels as long as you're not hard on them.

Personally, I would have replaced them but...........And arse_sidewards........Snap on has to pay for those fancy tool trucks somehow They do sell good stuff but a lot of it comes from outside sources just like the OP said........you can usually find just as good of quality at a lot cheaper price...

I would think knocking out the lug studs with a hammer, and then hammering in a new would, would be easier than chasing threads,
when you chase the threads you're still gonna have old lug studs.
just seems like alot more effort to save old lug studs,
it is possible to do, with the hubs still on, just watch this video, many other videos very similar.
HAMMER TIME!
probably the most fun thing to change on a vehicle.
one thing that will help in the future is to use anti-seize on the threads when you put the lug nuts back on.

good point. I just read the last part,
dont take a chance!
plus the lug studs are gonna be cheaper if you dont already have a 'chaser' or a tap and die tool that you would need.
especially if you're just gonna replace a few of them, I think they're are about $1-$2 for a wheel stud.
if you have a hammer, all you need is lug studs dude.
and maybe some penetrating oil like PB blaster or WD-40, just spray the studs you wanna remove, and hammer down.
The rotors on these old trucks are behind the hub, so no luck on the front axle like in the video. That approach may work on the rear? Seems hard on bearings to me though. Roller bearings don't like sharp hits like that but maybe they're big enough where they won't be hurt. I really don't know.
I'd try chasing them, and x2 on anti seize. Use a torque wrench to fully tighten not just full blast from the impact.
