and the distinct smell of gear oil as you come to a stop, it fills the cab with the odor. It started on a trip from Ottawa to Welland (5.5 hrs) heard some whining and the smell happened as I exited the highway. I got it home and noticed the leak today. I have an 03 with 196,000 enjoyable kilometers (Canadian truck). I realise I'm in for a repair bill but has anybody else experienced anything like this?
