So after i did my lift before winter 2010, I started to get a thump under the middle of the jeep. could be just small cracks in the road it thumps. I thought they were syptoms of needing BPEs do i got those and still happens. Now i think Tranny mount. I got under it and push up with my hands and it moves up, down, left and right. It sounds more below the rear seat more o to the back of the jeep. Im thinking the T-case hitting the floorboard when the tranny jumps. any help im probably gonna just buy one from napa seeing as they are $27 but would like some other thoughts
