Hey everyone, I need some help.

I am attemoting to rebuild the diffs on the Hyper ST RTR. I am attemoting to get rid of the grease and go with fluid. My question is where does the fluid go on the center diff? Do I a open it?

For the front and rear there is a diff case, so I am assuming I fill this up completly and put it back on the chasis.

Thanks!

I replied to you already.

You have to take the diffs out of the rear and front bulks first. Then open the front and rear diffs up. The center diff just remove, then take the spur gear off and fill.

Here is a picture of the rear diff case. Courtesy of AMAIN.

Before filling make sure you clean and get as much of the grease out as you can.

This is a picture of the center diff in a revo, but this will help you get the point of what it looks like at least.

Thanks! I really appreciate it!!!!

Also, its hard to tell from the pic, but from what I understand you only fill the dif to the crosspin, you dont have to totally fill it all the way up. I had the link to the Xray page that showed it but lost it.

This is a nice read also. [link]http://www.xtremerc.com/pages/howto.php?howto=24&page=2[/link]
