do you mean when you are running the slide in or out....or the creaking noises you get when driving down the highway?
Shwintek has some good videos on youtube for their slide systems.
Here's one for lubricating

It'll help with the noises when operating the slide in and out.
I seem to remember a bit of noise coming from my slide when I drove. That was when we fist got the unit. After a while it diminished.... or maybe I just go so used to it. Honestly, I think it was a little of both.
This reminds me, I should probably lube my slides again.....
I've been all over and through my unit...same year and model. happy to help with any questions that I can.
