Being new to E-Maxxes, I had a question I hope someone can help me with. Last night after running, I brought it home and was cleaning when I noticed that all around the seam where the differential goes I had dust stuck to an oily residue. Is it normal for the diff to seep here, or do I need to take it apart and tighen it up or reseal it? Also, I think I remember reading, but correct me if I'm wrong, it's nomral to have some oily residue on the bottoms of the shocks? I have a little bit in the rear, almost none in the front. Thanks for any suggestions.
