are you doing the drop near moore im about to bag the front of my truck here in a few weeks and would like to help just to get some more experiance if thats cool i dont know much about drops but want to learn
I've heard different stories about balljoint separation on NBS trucks, but here's my personal experience in dropping NBS trucks (don't try to separate the UCA balljoint like OBS): If you are replacing just the springs, remove them from the back of the control arm. Basically, once you have the truck on jackstands, put a jack under the control arm. After removing the swaybar endlink and the shock, ubolt the LCA from the frame (2 bolts), and gently (and slowly) lower the jack until the spring is uncompressed. Lower the LCA until the spring can be taken out. After that put in the new spring and reverse the process. Should take you no more than 30 mins.....
Well when I did it, By Ball joints were seriously stuck. I didn't want to ruin the lowers, so I separated the uppers instead since It would be better to scrap an upper balljoint than a lower one. I have heard that you can use the spring itslef to pop the lower balljoints out after you have disconnected everything(shocks, swaybar, balljoint nuts)
Just make sure to get the brakelines taken down and out of the way. You won't need any spring compressors, as the drop coil will be much easier to get on than the stock coil.
Not a tough job, spindles are another story but springs are tit. I popped the lca by unbolting the sway bar and ball joint and hitting the side of the control arm with a mallet. The vibration pops it out. Put a floor jack under the control arm though. Never did the uppers to get the spring out, have to try that on the next one. Good luck
