they said to use silicone lube... i used some WD and it worked fine

 

Where would i apply the lube?

 

I wouldn't use WD-40 as lube. You'll be putting it on every week. Gunk white lithium grease is good stuff.

 

Do NOT apply the lube on the window if you have tint. I believe it was the tint that made it such a headache. I had the same problem and shot wd-40 down the window track and it took 2 months to finally get all the grease off the window, it caused the window to be blurry.
