Keep in mind this is coming from someone who is not mechanically inclined lol
You reckon? It looks too clean and thin for that. When ive had boots go (even the slightest) it makes a ridiculous mess. Splatters everywhere.I'm inclined to think the boot for CV Joint has a tear and that's CV lube that's flung off. Can be confirmed by looking at the areas on the other side of the half shaft.
Second this. Then youll know for sure.Spray the area with Brake Clean, wipe it all down and watch the area closely every day to determine the location of the leak.
