Front right side right behind wheel

better look at the green sludge i cant seem to identify almost looks like grease


Felt like something blew or my wheel bearing just died out of nowhere on a drive yesterday. Tires just got changed at a shop which had previously screwed my dads truck pretty badly more then once. Driving home and the whole truck starts to shake and grind and almost like stalling when you're out of gas but two three times that. Pulled over and got out to find this, no idea what happened

 

That green sludge is probably grease. Try to find out where the grease came from by inspecting the tie rod and axle boots to see if you can find a tear.

 

I bet if you check that CV boot, you'll find a hole in it.

 

My sentiments exactly, looks like it's coming exactly from that boot.
