I've got a rear output seal leaking on my transfer case, so i bought a new factory seal from Toyota,
Now here is what i ran into with regards to replacing this seal, The factory seal has what i think is some type of dust lip sticking up about 1/8 of an inch from the face of the seal,
Problem is, all of the seal installing tools i have are flat faced disks, If i use one of those it will smash that lip while installing the seal, and could damage the seal,
So i machined a seal driver with a pilot to center the seal on the installing tool, along with a counter bore in the face of the tool for that dust lip to fit inside,
With this tool i can now hold, locate, center, and drive the seal into the case without worrying about causing damage to that dust lip,
In this first photo you can see how much that dust lip sticks up from the face of the seal,
In this photo you can see the custom seal installer i made, take note of the counter bore in it's face
This photo shows the seal being mounted on the installing tool
And this last photo shows the seal has been pushed flush on the installing tool
