Slide out actuator squeaking.

[RickV]

Been hearing a squeaking noise when opening and closing two of my slide outs. The noise is much more when closing then when opening. So I did some reading and thought the problem was that I needed to lube the pinion gear carrier. I did that and it made no difference so I had someone close it while I was underneath and the noise appears to be coming from end (where it is attached to the slide out) of the actuator. Is there a way to lubricate that? My 5ver has the enclosed underbelly and there are access points to the motor drives but the noise is coming from the other end.

You can get spray cans of slide lube. I'd spray everything you can get to a few times while having someone run them in and out.
