I have a 2004 Cayanne S with 145,000. After not using it for several weeks the right front tire will not turn, it is stuck. All other tires will move but that wheel will not.
I have checked the four wheel drive selector and tried both forward and reverse. There appears to be a lubrication nipple on the wheel by the brake hub , what does that get? could it be the problem? BTW I live in Maine and its been extremely cold this winter. I did use it in the snow and it was great. I left in April so its not been used for a month.
