Is this just grease from driveshaft? (1 Viewer)

Just got back from a 500 mile round trip vacation. Right before leaving had my oil changed and drive shaft greased. Looked under truck tonight and see this red stuff - first reaction was coolant but on further inspection it looks to be grease. Am I right?

Yup. You can mitigate this by wiping down the u-joints of any excess grease that comes out after greasing. You may also smell it on your exhaust.
