Ok just finished replacing the gears in the front diff it took 4 shims on each side of it for just a small amount of play, but i have 1 more question.

When i removed the old diff fluid it was a "silver" color no longer clear, is this anything to be alarmed about it was the same in the front center and rear.

BTW i went with the 10k front 20k center 3k rear well see how it works out on Saturday

O yea also how often do you open up your diff cases and re-lube, when i spoke with Tim at kyosho he said that a gallon was alot to run through the truggy without opening up and relubing the diff gears.
