Squeaky slide out

[FrankPace123]

We have a 2010 Hickory Edition RK3000. Lately the main slide out makes a loud, squeaking as the room is actuated either going in or out. I've lubed the seals and the visible rollers, but the noise persists. I'm assuming there's another set of rollers in the belly that need to be lubed. If that's the case, is there a way to do it without removing the belly cover?

BTW, I tried using the search feature, but it takes me to the google site even though the MOC is marked.

Thanks in advance for any help.

The square rails also need to be lubricated

You should lube the gear teeth on the square rails with a PTFE lubricant. But the most likely source of noise is the gear pack. Below is the link to the owners manual for the slide out system and on page 12 are the instructions for lubing the gear pack.
