Fixing the passenger window regulator is on my roundtuitt list. I bought the Help! kit with the three nylon cylinders. What grease would be best to use in the gears?

 

I did mine a few weekends ago and just used some multi-purpose automotive grease.

It made such a difference. I could turn the window crank with the tip of my finger.


The one thing to keep in mind when greasing it up is to grease the flat, broad sides of the gears, since they do slide along each other.

 

Thanks. I forgot to mention mine are electric but, I was thinking chassis lube for it also after cleaning out the gear box.

 

It should still be the same. As far as I know, the motor just spins what the hand crank would spin. All the regulators and gears are the same.

Yeah, that's probably the same thing. Chassis, wheel bearing, multi-purpose grease.
Just be ready for your cab to be a little "strong" smelling for a few weeks.

 

Personally, I don't lube those parts with anything petroleum based that stays put for long. The environment inside the tailgate is one of dust and road debris that comes up through the drain holes and down on the surface of the glass each time its raised and lowered. Dust/dirt and oil or grease is a recipe for sticky mechanisms. Graphite the heck out of it. I use a product that unfortunately cannot be purchased anymore but can be mixed. It consists of a very light (I'm talking sewing machine) oil mixed two-to-one with powdered graphite. The oil is light enough that it dries up quickly and leaves the graphite behind. Since the oil will wick into the crevices, it carries the graphite deeper into the mechanism than it could get on its own. The mixture will not remain blended for more than a few hours so if you have any left over you will have to shake it thoroughly to use it again later.

 

Thanks gs. Too late on the tailgate. I did it last year with wheel bearing grease. Do you suggest your mix in the worm gears of the passenger window?

 

In a sealed gear-head I wouldn't worry about dust contamination as much but any location that has components bearing on each other and exposure to the elements is possible, I use "lamphouse" lube. (Which is what the stuff I mentioned above is called in the industry it was employed.)
