Could anyone tell me what this fluid is that's coming out from my front driveshaft slip? There's only a very little bit of it that dripped down onto the cross-member below it, and it's an oily consistency with a reddish hue (see pic).
I did just hit all my chassis zerks with some grease, definitely not overgreased, so I was figuring this could be a little grease contaminated moisture that might have been pushed out? I know some grease might come out of there while greasing, but I only ask because this is a little more viscous than just grease.
Possibly a stupid question, but this shaft isn't filled with fluid from the transfer case or front diff is it? Because then this may be of concern.
