I decided to try and replicate Steve's setup on my new 4x4 PE. This is my first Traxxas vehicle and when I went to remove the grease and replace it with 5k diff fluid I was surprised that the diff isn't sealed. Is there a trick to getting this to work without leaking? I'm already seeing some leaking from around the left bearing. If you have successfully done this how full did you fill the case? The more fluid I add the faster it seems to leak out. I'm going to be rebuilding the front diff shortly to replace the 30k with some 10k is it a similar setup to the rear?

Thanks for the assistance...
