What grease is best for nylon gears?
Permalink  

I decided to have a go at fixing the power antenna from my Park Avenue. A member graciously sent me an entenna however its different from what's in the car (It may have to supply it's cord if my fix doesnt work). Mine had a broken cord and I used an interesting tip from a Youtuber for a fix.

Anyway, I need to clean out the old grease that the factory used and was wondering what would be the best type of grease to replace it with? I know the antenna itself should be lubed with a light oil like sewing machine oil. I'm more concerned about the nylon gear. I was thinking dielectric grease? Thoughts? The factory grease looks like standard bearing grease but I'm not 100% sure. 

Arrows point to where grease is needed:

If it was mine I'd be using a very light lithium grease because I would think something like a wheel bearing grease would be too stiff in the cold weather.

Also I know some guys say to lube the mast with graphite but if I am remembering right GM recommended extending the mast fully and wiping it totally clean with something like brake cleaner. I think the idea was any kind of lubricant on the sections caused dirt and grime buildup which in turn causes more issues.

I recall when I worked at the Windsor Transmission  plant that lithium grease was used on internal nylon gears.

From Google.....

Is lithium grease safe for nylon gears?
 
 
The answer is: yes, it is by far the best lubricant for nylon gears. No, it will not do anything bad to your gears. White lithium grease works perfectly with nylon gears. People have been using it for lubricating RC servo gears for forever.Feb 3, 2021

Super lube if you don't want to do it again in 60 years lol!

Lithium will separate over time.

I'm just going by the state of the grease as found in the window motors Todd. The power seat drive transmission and actuators I've gone through were Pretty hard, but I'm sure fresh lithium would be just fine.

One thing I'm onto now, is to not overdo the grease. Anything not on the contact faces or bearing surfaces really is just a dirt magnet like Carl suggests. Nylon on Nylon Helical or Spur gears probably can be left dry faced. Worm or metal/metal, metal/nylon might need a touch.

 

I really do like the Super Lube though. Have gone through two small tubes over the years, and have a tub of it now.  Seems to have all the right properties for small gears.

 I've mentioned this grease before, it became my go-to grease a few years ago.  I got mine at Home Depot, but while it appears on their website, there is no availability.  Gregg Distributors also used to carry it, and while they have many other Super Lube products, they don't seem to carry this specific one.

Looks like it'll be Amazon.ca fory next tube.

 I have to second what Mark has said. Super lube will still be "pliable" in below freezing temps. I know the car will probably never see temps that cold, but super lube will not solidify like lithium over time.  Even silicon paste which will be nearly as good as a lubricant
