hey i'm plannin on instaling my tein stech this weekend and i'm not sure what kind of grease i need? also which is hard to install the front or the rear? THis is my first time doing any suspension work, but i'm not a total newb when it comes to working on cars.( installed my cai and exhaust, and worked on my old dsm)but is this even a good idea to do it myself? i've been reading alot about the diy and thinkin i have a good idea of what to do. has anyone else ran ito any major troubles doing this install?
