[QUOTE="FishFam JKU, post: 445030, member: 21779"] Yet another random noise from the 08' JK Rubicon. I can't isolate and identify it but looking for steps to do so. Sound comes at temperature at all speeds. Moves with speed regardless of gear (automatic). Both diffs had fluid changed within the last 3k miles. No sign of excessive wear in the fluid. Yesterday I pulled the front drive shaft and been running 2wd. Now I can't replicate the noise. I have yet to run the T-Case in 4wd with the shaft off but not sure if that would identify anything? Drive shafts are Reels and is in good shape, u-Joints all appear to be in good shape. The only thing that keeps coming to mind is the Front Output bearings on the T-Case but I don't want to tear into that beast if I don't have to. Any way to narrow down the front/rear pinons, T-case or Transmission? Thanks Scott [/QUOTE]
