1st gen Nissan Xterras are known for getting a power steering leak from the sector shaft seal (the shaft to which the pitman arm attaches)
I'm wondering if it makes sense to lather on grease on the outside as a preventative measure to protect the seal?
As you can see, there is a bit of an indent on the gear box body and the dirt and dust seal is a bit inset. I'm wondering if it makes sense to pack/fill this area with a nice thick waterproof grease to protect the seal from road salt and dirt?
Just to be clear on the set-up: there are two seals - the outermost is a dirt and dust seal, then there is a snap ring, and then the oil seal is deeper inside. Obviously, it's the oil seal that wears out and leaks, but I'm guessing that's primarily because dirt works its way up past the dirt/dust seal and wears down the oil seal. I figured if there is grease on the very outside, facing the elements, it will create a barrier for this.
