How bad are these lower control arms and how far can I delay them? I understand that we can’t just press new bushings onto these LCAs like in some other cars for eg our GX460, I just pressed new bushings onto these.

 

Edited - I mistakenly thought you were asking about the rear LCA bushings, but now I see you are referring to other LCA bushings. If your suspension is firm and you have no handling issues it is probably OK for a little while.

In case you are also looking at the rear bushings see below.
Original reply:

How does the handling perform under hard braking? I think the rear LCA bushings are oil-filled, and if so they could potentially leak with the type of damage I see in your photo. Even when working properly, these LCA bushings allow some toe-out during braking resulting in inner tire wear in the front.

I don't know if these could be pressed out, but I think it's possible. I replaced my LCA bushings with the following (stiffer bushings used on the GS-F and LC-F). Pricing from Amayama was reasonable.
