What you are seeing is the white grease that we use in our kits. You can clean and refill your diff with either white lithium grease or you can use a silicone racing grade lube at 5,000 weight to replace the stock grease in your MT2.

The grease will be thicker when it is at room temperature and will become more thin as your run your truck and the heat builds up.

Hope this clears this up.
