If the balljoint binds they are cut to make the balljoint at a better angle to lay and get the most lift possible. I put a tech here on doing it. Toyotas don't really need it unless you have stock spindles and a larger 18" tire, or drop spindles with decent sized 20s.
i just finished my 94 toyota it has stock arms, 2 in drop spindles, stabilizer bar, i had to pie cut them so i could lay out flat without zing the frame with 20in by 9in rims. no z and layin flat oooyea
