Leaky diffs

Well, I have about 50 packs through my 22-4 2.0, and the rear diff seemed a little light and the rear wheels were a little loose under power, so I opened it up. Getting to the rear diff isn’t TOO bad…

• 3 screws on top
• 4 screws on bottom
• 3 screws on belt cover
• 1 screw wire stay on servo mount
  
• 2 nuts shock mounts
• 2 screws swaybar

So 15 screws to get at the diff.  You don’t have to do the last two steps, but it makes your life a little easier to get the shock tower off to the back of the car.

Looks like the fluid had all leaked out, there’s not a whole lot in there so it didn’t really make a mess, but I’m guessing it will tend to leak through the o-rings if anywhere.  The only sign was a tiny wet spot on one outdrive.

The outdrives were on pretty good, so I ended up having to stick the diff housing in a vice and use a small flathead as a chisel to pry the outdrive from the housing.  I guess they were on a little TOO good.  I think motor spraying the black oxide parts makes them super clean for assembly, but they will tend to gall together.

One rebuild kit can service two diffs, which was nice.  Hopefully it stays together better this time.  I didn’t pop open the front diff, but I didn’t notice any leaking and it still feels pretty good.
