2017 Ram ball joints vs complete LCA

What's the mileage on yours? There's a line of Mevotech that is lifetime(that's my plan). Stealership is 3 yrs(I think).
I bought Mopar upper and lower arms from a dealer but I haven`t gotten around to replacing them yet on my 2014 ram 4x4 1500. I was thinking they should of lasted longer than that.
I had planned to do a tire change anyway, but not till spring. Still some tread left after 130 kms, but LOTS of cracking between treads.
Good news Steve......Easier to replace a tire, but probably just as much $$$
