Window sash lubrication

[Thealien]

What are you guys using to lubricate where the rollers go in the window sash for the side glass?

I am installing new side glass in one of my blazers soon and I’d prefer to do it once and correct.

Thanks

Will it be a problem if the sash is installed about 3/16 to 1/4 inch forward on the glass? My glass guy who is a friend just centered it and an original glass I removed from another door shows it a little more to the rear. I don’t want to make him redo it if it’s not needed. And I also don’t want to install it to find out he needs to redo it?

I use Dielectric grease. It seems to work well.

White lithium grease is what I always used in my glass shop.

I've replaced a lot of side windows on a lot of different cars and always lubed window regulators with Valvoline synthetic grease. It sticks and doesn't get hard, even in cold temperatures. For the glass run channels, I always clean them really well and wipe on a tiny amount of silicone lube. Doing that will even make an old window work better than a new car.

Thanks gentlemen. Any thoughts on the sash placement mentioned above.
