Although the kit come with ball diff grease, I opted to use the Team Associated.
Grease up both Diff half's & Place a spacer/plate over each diff half. Then put a little grease on the plates.
Put a little bit of grease on the diff balls.
Place the two 5x8x2.5 bearings in the open ended diff half. One will sit inside & one will sit on top .
Place your 52T diff gear over the diff half with the bearings in.
The start to put your diff balls into the diff gear. I like to use the diff grease tube so the balls stick to the end!
I just put a smidgen of grease over the balls for good luck!
Place the other half of the diff over the gear.
And prep the rest of the parts for putting it together.
a M10x0.3 shim & a M10x15x5 on each side of the diff.
Put a little dab of Anti-wear grease on the thrust bearing & place it over the M2.6x22 diff screw.
Put a M2.6 lock nut inside the diff nut, then place the M1.3x2 spring in the end of the diff followed by the diff nut, & place the diff screw into the other side.
Tighten down all the way until its time to bed the ball diff in at the end of the build.
