Sorry, not sure then. (stick here) I wouldn't think its an indication of anything bad coming though, (but i'm no expert) I know when its cold my shifts are a noticeably stiffer but I just attribute it to the fact everything is a little more compact/tight when its been sitting in the cold all night. I had an old Ranger that I bought in Florida and it hated when it got cold here in Virginia. It would make all kinds of sounds and act a fool until it was warm again, never had any issues with it though.
