This is gonna be somethin new to me, so i would like some info from some of you guys that have done this. Is it an intense project to do, and do you guys think that it is really worth doing. Im not a hardcore everyweekend wheeler, but i do wheel often and when i do I have a problem whith breaking the crappy stock nissan axle, or tie rods. So do you all think that a straight axle in a nissan is alot better.  

How hard, how exspensive is relavent to what your recources are. I'm all for SAS. I've done it and continue to refine it. Some will tell you it's a breeze and can be done cheaply. Others will say you need a 2nd mortgage. People have done hack jobs all the way to factory like. What your budget, skills, wallet, recources, want and/or needs are what will most likely determine the type of build you undertake. If you want SAS tech for Nissans check out www.nissan4wheelers.com
