2 Questions About Rc Leveling Kit

[mfennema]

First, when I installed mine the other day I put the bolt under the driveline in from the bottom up with the nut on top. Is there a problem with doing it this way? I didn't want to have to remove the driveline to get it in from the top down. The other side I put in from the top down.

 

Second question, by adding this kit am I putting my warranty in jeopardy?
