2017 Ram ball joints vs complete LCA

4spdragtop said

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 the ball joint actually showing wear or looseness? If not, I would rotate the tires front to rear and see if the wobble changes. Does not matter how many miles are on the tires for them be a possible cause of a wobble or shake.

If the ball joint is worn you just need to pick the replacement method you think you are comfortable with. Either way is perfectly acceptable IF the new ball joint fits tightly into the old control arm. If you try doing just the ball joint and it goes in too easy, you really should replace the control arm. Sometimes that motivates people to replace the whole arm so it can be a one and done repair.
