I actually have all three of these vehicles, and cannot get the diffs to seal. Every time i go to take it apart some diff fluid has leaked out!! usually 3 race days

Is there any trick to gettin them to seal properly??

Never owned one of the AE models but lightly sand the diff case and get a good quality diff gasket. Also use grease on outdrive shafts to help seal that area.

most people from what i have seen use mugen diff seals, and just sand the case, also try get the clear coloured diff seals they are supposed to help alot to.

Using a light coat of red gasket sealer does wonders. tho, you will need to replace the gasket sooner than usual, the sealer tends to make the gasket brittle. If youre leaking from the out drives.. then you should upgrade to the new clear o-rings. Theyre a running replacement to the black o-ring.. meaning they have the same part number..

I have even used a flat file before...
If you want to use sandpaper I would use something like 800 grit and make sure it is on something very flat! You just want to take a little material off.

800 grit ? would be the way to go.

I would start with 400 grit.

But, another possibility is that you might be overfilling the diff. If you fill the diff way beyond the cross pins it will leak no matter what you do.

Sand the diff case down a touch, but the main thing is to get the new o ring set. The large o-rings will be clear instead of black. They provide a better seal. A little grease on the input cups, (where you insert the smaller o ring) never hurt anyone either.

AE has newer diff seals which do not leak like the old style. The new style are clear rather than black. If you use these you should not have leaking problems.

You don't need to sand anything or use silicone to make a good seal. As long as you use the newer clear seals and a fresh paper gasket (and replace these parts occasionally) you will be good.

Also do not over fill the diffs. Fill them so that the cross pin is covered.
