I'm a 'bonified' newbie as far as LC's go...so "hello" to all and I'm thankful for such an informative site about our vehicles. I'm getting a strange 'whirring' noise coming from the rear of the vehicle in overdrive at approx. 55mph under load / acceleration...any ideas? TC, Trans., Rear Diff.? Other than this noise...the vehicle drives out great! Any / all help is very appreciated...Thanks
