I say yes, do it.

I like the fact that my CVs aren't spinning on Highway anymore. Wait, did I mention I did it because of my lift? :-)

 

We just bought a 99 4runner w/ a lift already installed. I want to convert to manual hubs as well. Where do I get them and what do they cost? I really need to keep cost down, as we have new born and funds are tight right now.
