Recently I have noticed a high pitched harmonic whine at 70mph. As soon as ilet off the gas it goes away. It is def tied to vehicle speed and not engine speed. I noticed last week when working on the Jeep that the rear driveshaft is slinging grease, however i asked the advice of a mechanic next to my work that works on truck/humvees and he said it sounded more like a ring/pinion issue.
Any thoughts? More important what would be the damage in time/hours? Im hoping for just the DS as that is a simple/cheapish upgrade.
Thank you for your help!!
