If you haven't done so already, I'd recommend a diff drop kit. They're cheap and will save your axles some stress. I'll be completely honest, and this isn't good to do, or admit, but I drove around on a ripped axle boot since 2018 up until April of this year and had no issues, clicking/clunking, anything. Again, definitely would not recommend.
I ended up going with the Napa 1258 heavy duty axles (new, not reman) but they are basically Trakmotive axles, which can be found on RockAuto for about half the price I paid. Link is here:

These will fit your truck and are currently in stock, so grab them while you can!
So far, I've had great results with them. If/when you do your axle job, I'd also recommend doing your axle seals, no matter the condition of them. Might as well do them while you're in there, and OEM seals for both sides came out to about $50~ for me. Not a job you'd want to have to do after installing your new axles.
