Vadim,

First, I openned a new topic so this would not get lost. Topics are cheap.

Second, WD-40 is not a lubricant. So says the manufacturer and I have experience that confirms this. It may, in some cases, behave like a penetrant
but that is just a happy accident. WD-40 is and was designed to be a drying agent.

Lastly, there are no external parts of the ride height control that require regular lubrication. Here, WD-40 might help, but just to reduce the
corrosion of the metal parts, but it may also injure the rubber bushings in the control link, if they still exist.

I'll take a bit of exception here. The late model photocell controllers had a lube or foam or something inside them which at its current age, will
glop up and cover the photocells. Disassembe and clean, and they work as well as they did new.

Mat, Thank you for posting this a a separate topic. Your insight about possibility of damaging rubber parts on ride height controller is confirms my
suspicion. It is EXACTLY the reason why I did not want to start spraying anything in sight without additional info from the collective
