I can't take it anymore, I must fix the vibrations caused by a 3 inch rubicon express lift kit i put on. I know it is going to take a SYE. Right now I'm thinking about using Rubicon Express, I know Currie also makes one. Does anybody have any suggestions, I kind of like the Rubicon Express one, but am open to any suggestions or comments becuase i know little about these things. Also these are the numbers stamped on the front of my rear axle can anybody tell wheather it is a Dana 35 or 44. On area says 46587AY, another area says 8277 or 8217 (couldn't tell). Then there is an A with a 3 right by it. Thanks for the help guys.
