HWH Levelers
2003 Challenger 347 with HWH 210 Series levelers. Single action spring retracted pistons. Have to pry the fronts up, but they will go down with authority and am able to level the rig. Once asked to re...

I still have the old style springs on mine and they work fine with some silicone spray once a season. Sometimes when I hear a creaking sound that is an indication that it is about to stick. It is only the front left that does this. The points that Bud was talking about are the roller and small cylinder that need to be cleaned.
And where specifically are these two components? Are they part of the control panel?
As to which lubricant, I've been in the marine field for almost my entire professional life, and rarely had a use for silicone spray vs the WD40-type. except when lubricating o-rings. I also use silicone grease when putting together pool equipment components, for instance. For petroleum based lube, I like one called Corrosion Block, from H&M. But if the goal is to loosen up tight seals, maybe silicone has an advantage. Since I have two tight cylinders, I'll try one of each and report.
YOUR Jacks are NOT the same as this post. The post refers to KICK DOWN HWH jacks.
1. When they cannot retract and you CANNOT push them up with your hand and must use a lever to get retracted-------NO LUBE OR NEW SPRINGS WILL FIX THE PROBLEM----PERIOD
2. The ONLY correct fix is to either replace or rebuild the offending jacks, the internal seals are bad.
3. 2003, I would also replace all 8 springs. You have the older springs that lose their tensile strength. New style springs will quicken the retract when the jacks are fixed and odds are the 15 year old springs are rusted and will probably break in a few years. Doug
