If the gap is rust free you can probably skip it.

Did you clean all the WD40 off, and out of the gap? I'd probably clean it with soap and water and then blow it out with air....... or maybe alcohol (the 90+% stuff) in the gap, and then blow that out with air.

Disclaimer...... I've never worked on a HF driver, I'm just tell you how I would approach it, given my experience in cleaning other things.
