Trim pump has Ratcheting sound

[RCSConstruction]

My trim pump works, it moves the drive up and down, but when I go down from when it's up completely up (parked) it will emit a slight squealling noise that makes it sound like it ratcheting down. It's not, it's moving smoothly. Weird thing is, if I go down all the way, then come up, BUT not all the way up, there is no noise going down. Only when I cycle it completely up will it make this sound going down.
I've checked all connectors, no voltage drop, etcc. Any ideas?

Have you checked the fluid level?

10-4 on fluid level.

Does something happen when the drive is raised all the way up? Does a relay click off/on?
I know when it hits it's limit, it seems like the pressure stops or something, so I was wondering if that would be the culprit.

You need to lube the rams on the drive.
​The seals do such a good job that they wipe all the oil off the rams.
​All the way up spray with WD or White Lithium and cycle a few times repeating the WD

Will give it a shot later today, thanks!

Drive still the same after spraying rams with WD40.

Any other guesses?
