Forgot to re-install Pinion Oil Deflector: Problem?

[Hurtin'4ASquirtin']

Hello,

Just finished installing a new pinion seal on a 2006 Ford Ranger 3.0L Automatic RWD.
Upon clean up I noticed that I forgot to install this piece, e6tw-4859-aa.
Drive pinion oil seal deflector. (#7 on the diagram)

Will this be an issue if I don't re-install it? I'm kinda hoping that I won't have to pull everything off again.

I think I forgot mine, way back when I did the axle. As long as you have a good fresh seal in there, you're ok.
