What can I do to help the angles of my driveshafts? I have 4.5" springs and 2" shackles. There's only a little vibration at 55-65, but it's also time for new tires. So that may be contributing. Both driveshafts are at severe angles though. You can start to see the splines on both of them. The guy I bought it from said he already did an SYE and added a new Tom Woods drive shaft in the back. It looks like there was already a small transfer case lowering kit added. Can I just put on a bigger transfer case lowering kit? Can post some pics if that helps.
