oil leak - from the spare tire?

I posted this a while back, but no solution was found, so I'll try again...

At the rear of the MDX, a small amount of oil drips from the bolt that hangs at the center of the spare tire. Just enough oil for a drop the size of a dime. Doesn't happen all the time, but quite frequently.

Dealer said it was from lubricant used on the spare tire cable. They cleaned it off, but the leak is still there.

Anyone have the same or similar problem?

This happened before and after I replaced the donut with a full size spare. It now leaks onto the tire cover.

I think that the lub type in the cable housing is solid while the outside temp is cool or cold. Once it gets hot , like now, the lub liquifies and drips down the cable and onto the garage floor or in my and
DaleB's case, the spare tire cover.

I think that the only way to stop this is to change the type of grease in the cable housing. For long hot summers, I would think that nearly all of the standard grease will liquidy and run out. Maybe the dealer has a different lub than is being used by the factory. Any good graphite lub should stay solid and not run and keep the cable nice and slick. However, it is not obvious how you would get the new lub where it is needed. Perhaps a dealer problem.
