Yep, that looks like Moly grease in those wheels - filthy stuff to remove! Bit late here, but a 50/50 mix of petrol and diesel works well at shifting it.
I used to have to do that on the CV joints, and inside the steering knuckles, on the front end of my old FJ45 Landcruiser when I serviced it. It was quite a regular job, as I used to take that truck through river crossings up in the High Country quite frequently, back in the day. I was buying 2.5kg pails of Moly grease, for that job.
The thing about that grease in your wheels though is, it shouldn't have been there! The manual says 'Grease the Dust Seals with Multi Purpose Grease. Do not grease the gear teeth.'
Cheers, Gadge
