I started getting a "diff grind" at full throttle but not on lower speed ups. When I opened the centre diff, I found exactly what you found - black thick putty and nowhere near enough to fill the diff. Looking forward to see what fresh diff fluid will do for mine too.
I put a set of front CVDs on the rear of my sledge due to them being 2mm longer and it seems to have fixed the dog bones popping out without having to use an o-ring. Might be worth a try
Believe Traxxas are now shipping with the O rings, we fitted O rings to ours and not had a problem, but yes the CVDs are an option we will look at when we need to replace
I am a little confused by thick centre diff oil effects. On the one hand you have less diffing out and more more power going to the rear so you should have more wheelies. On the other hand the fronts should be rotating at a lower speed as it’s harder for the centre to diff out. Is that the reason you get less ballooning under full acceleration?
I want to like this RC and keep going back and forth on whether or not to purchase. Sledge, Maxx V2 or Kraton 4S are the three I am choosing from. My concerns about the Sledge: price, motor mount, aluminum chassis. Not sure why Traxxas went with an aluminum chassis on this one. Metal chassis’s just don’t hold up well over time.
@pewterngold I have both and the sledge is the way to go. I like it better than my xrt even. The maxx v2 Is the best for all around. But the sledge has so much power and so much fun. If you were to only pick 1 rc to have I would prob pick the maxx though.
It will wheelie easier as it will keep delivering more power to the rear wheels. So great if you want to make it flip or wheelie if driving normally then you just have to be a but easier on power. Wheelie bars are needed for this truck. Come on Traxxas when will they be available.
Clay carving tool is so perfect for putting diff lube in
Yes I suppose it would, small flat head works as well

It will wheelie even easier!!
Great video guys! Will be checking my Sledge this week and already ordered the diff oil for it, just incase!
Worth a check for sure!
Need to check mine aswell. But I only got 1 mil diff oil at the minute, need to order some 20mil
Thanks for the good info 👍

Have you checked your front and rears yet? Should be about 1M rear and 500k front I believe is most recommended. Love the vids and your track 😍👍
Thanks for the feedback. No we haven't checked as yet. It is on the to do list
I have just done this but put 1mil in both front & rear.

Basically yes. Power always goes to path of least resistance . So heavier centre will make it wheelie more but less front ballooning
yeah why DO traxxas not fill them.....`and what can we does to fix it?
Service them and fill with oil!

Depends what you are doing. Big jumps will bend alloy chassis
@@TeamRC3D do you own a Maxx V2?

Will doing this cause it not to pop wheelies as easily too?

Wow - that diff was empty!!!
It was starved of oil! Wonder what the others are like!
@@TeamRC3D mine was empty

Pack them FULL
