Well my dealer said "we hear it, but can't figure out what it is. You have lots of time on your powertrain warranty so just drive it for a while and see if it gets worse or we'll see if Jeep issues some sort of TSB."
On another forum I read a post that stated "FYI, there is a very recent TSB (issued February 24 I think) about drone noises at high speeds; the TSB tells the dealer to put the vehicle in some sort of mode (done by hooking it up to their computer) which basically let's you drive the vehicle while the four wheel drive is disabled. If the noise goes away while in this safety mode, the TSB tells the dealer to REPLACE the front prop shaft. Unfortunately, this TSB did not fix my vehicle's drone (it still made noise in safety mode)."
I can not find the aboves tsb. Someone earlier in this post said a front drive shaft fixed their problem. Can anybody confirm this tsb or that a front drive shat actually fixed theirs?
