Well, I've read some writeups on regearing, and if you're no pro, it will take you ages, let's say 3-4 days because you're getting stuck with parts you need, and lack of experience; at least for me, this efford isn't worth what I will have to pay for labour... Maybe in some 30 years when I get retired I could try this kind of things, but now it's just too time consuming.
BTW, it's not that I'm lazy, I installed the whole suspension lift of my XJ myself (LCAs, coil springs, shocks, leaf springs with some home-made mods), but I did it because a shop wanted about 100 - 150 USD for the labour and it took me one saturday, so I thought it was worth it.
