With my 4" susp lift there was some vibration in the back so I installed a t-case drop down from Skyjacker, the spacers are 1.5" long. Question: I adjusted the linkage for the t-case and column shifter but there's a strange sound when I have it in Reverse. When in gear and not even moving It feels like a super rough idle or small grind, shifting it into P-N-D-2-1 is like it normally is, smooth idle... Does the motor get torqued differently in Reverse?? Don't wanna drive it too far until I figure this out but other than that it feels the same before I dropped the t-case... Anybody experience this? Any suggestions?
