2017 Ram ball joints vs complete LCA

Hey, looking for some advice here as to which way to go. Truck developed slight wobble(enough to foam beer while driving) :lol:
So I pulled tire and all looks good brake wise, so I'm fingering it's the LBJ. Truck only has 130kms(80k miles).
I can get lifetime LBJ for approx $103, OR lifetime LCA assy for $400.
Both are Mevotech TTX line(heavy duty).
There is also a cheaper line of Mevotech that's lifetime for the LBJ, it's $70.
Do you think it's worth the extra $$ to get a complete LCA?
I would do both sides
Thanks
Steve
Is it a diesel? Loaded is the way to go. Might as well replace both sides
