Any of you folks know what I can do to silence the mainroom slide out noise when extended or retracted?

The smaller bed room slide is silent, the other you can hear a blick away.

Is there lube or somthing taht could be the problem?

Thanks

It depends on where the noise is coming from .... could be some dried out seals or squeaky rollers. try to isolate to a specific area of the slide and then narrow it down from there.

When mine was noisy it was determined that the hydraulic pump pressure control was not not set properly and the tech adjusted it, which reduced the noise. The it was discovered that the rod which is attached to the slide and moved with it to activate the limit switches was dragging on the trailer foundation where it passed thru. A little lubrication quieted it.

Use dry moly slide lube. Anything sticky will attract and hold dirt, dust and small stones. This combines to form a crude grinding compound and while it may be quieter, is wearing at an accelerated rate.

Dry lube user here too. On a regular basis. Also is a wise thing to keep your seals clean and sprayed. They can be a big source of noise.

Check th e5vr owners manual, it should tell you what to look for, where to grease and what to grease it with. I use AMSOIL HD Metal Protector, which is also used on motor cycle chains and will not attrack dirt.
