Should I take it apart and add shims so there is no movement at all?
Hi Barry
Have you found that you had to change the setup from what you normally used with a ball diff, I found you have to keep on the power more into the corner.
Any chance you could pm me your setup please.

Cheers Malc

I dont use the gaskets that come with the gear diff I just used gasket maker from autozone and my gear diff doesnt leak at all. When I tried using the gasket supplied with the diff the two pieces didnt completly seat together their was like an 1/2 mm gap

I just bought a new spec r diff for my 417 and I have a problem. It binds a little bit don't know if that's normal or does it have to smooth? And I did polish the gears as well.

.

They need to be smooth. Use very fine sand paper. Sand the back of larger diff gears, then reassemble the diff and try again. Keep doing it until it is smooth. If it is not smooth will strip the gears easily. It will take sometime as it took me 45min last night just for this process.....

Ok so I polished the hell out of it and it got a loooooot better. But I still feel a little bit of the gear when going left to right or is that normal?

Malc,

What oil are you using in the gear diff?
I tried it back to back with a ball diff and had more rear traction and slighly less steering but way more control of the power out of a bend.
I run 1K oil.

If you need any setup help just drop me a PM

yes, as there will be some play between the outdrive and the diff case. if you push the outdrive in and turn the diff you will feel the diff not really smooth. As long as it feel smooth if you just turn it "normally" it is ok.
