If you were considering the Whiteline anti lift kit, that would be the best time to install them. The stock control arm bushings are not known to fail prematurely, but the WL anti-lift kit come fitted with harder durometer bushings.
The Whiteline ALK is installable without dropping the subframe. the Anti-lift kit replaces both rubber inner control arm bushings with poly ones that push the resting position forward ever so slightly. basically all other lower control arm bushings you can get would replace the ALK's. Whiteline sold a full control arm assembly not too long ago and i would recommend getting that so you can also get a roll center adjuster as well as a thicc bushing and bracket. As far as i'm aware the only one you can replace under the subframe is the front swaybar bracket bushing which i've only seen sold as part of a swaybar kit.
