Lubrication
Hello all,
I have a general question on lubrication of various coach components. Often, I hear different comments on lubrication, grease and what to not use. Would like to hear your opinions on lubrication materials and grease products. For example on the following applications:
HDC Lifts
Qwickie Steps
Chassis lube and grease.
Slide lubrication.
Any other areas?
It's odd the manual does not seem to address this?
An example I hear is use silicone on the lifts. So I assume a dry silicone? What about white lubrication grease? Any use for that? Do the steps need special lubrication or will any dry lubrication work? Thoughts using WD 40 at all?
Thanks so much for the wisdom.

I just took delivery of a Thor Challenger. I was very surprised when the dealer told me to use WD-40 on the shafts of the hydraulic levelers to prevent rust. I asked him why he would use a solvent to prevent rust and he said they hadn't seen it cause any problem to the seals. Very strange. WD-40 now markets a rust preventive spray product. I haven't used it but it might be worth checking out. I've used white lithium grease both from the tube and spray with good results. Read your manuals, some of the manufactures recommend silicone lube for many applications.

I did read on one of the forums that one some had used motorcycle chain spray lube for the Quicke Steps, I just use motor oil. As far as the chassis lube, I have opted to use a synthetic chassis grease. I do not use WD40, stopped using that years ago.

Just my opinion, and what I remember reading. First WD 40 is for breaking bolts loose that need to move. Not a lubricant. My jacks have grease zerks, plus they recommend wiping the shafts with transmission fluid, I sometimes spray silicone in them. My steps, are recommended to use spray lithium white grease. My Rv mechanic recommends a spray graphite (SP) for the slide moving parts and gears. Chassis lube, any high pressure (HP) grease. In the Workhorse Owners Forum there is a long discussion on U joint lubrication. On Mine, the drive shaft is the parking brake, so the joins are under pressure..Basically you take all pressure off the ujoints, block the wheels so it will not roll, neutral, brake off. pump grease until it comes out all four joints, pump out all old grease to remove moisture and grit.
My opinion is worth what You paid for it..

My levelers run on dextron. I wipe the rams with it. Then wipe with a dry cloth. Regularly.

HWH recommends transmission fluid IF a wipe down is necessary. Usually just hose them off.
WD-40 is not a lubricant. WD stands for "water displacement" and it was the 40th formula tried, hence the name. HWH also recommends zero lube on their slide outs.
I use dry silicone on the steps.

Mine do as well.
The chassis manual will spell out exactly what lubs to use where and when.

I recently had a problem with my electric steps sticking and not retracting completely. Chain/Cable lube spray solved the problem. I had been using Kwikee Lube, but couldn't find it locally anymore.
My power gear jacks have zerk grease fittings. I grease them once a year and I'm good.
Protect-All makes a very good spray dry lube for slide mechanisms. I use that, along with their rubber seal protectant on the slide seals.

Lubes
WD40 has a problem because when it evaporates what is left is very similar to cosmoline. Similar to a sticky wax. Anyone who has cleaned a preserved firearm would be familiar with it. I use dry silicone on the jacks and Tri Flow on the steps. Tri Flow has PTFE and does not show static properties that would attract dust.

I use Boeshield T-9 for a variety of applications. Steps, generator slide, slide gears and track, Pacbrake lube points in addition to coating the engine valve cover and the portion facing you as you open the engine compartment (side radiator).
I have also coated any areas of the undercarriage and generator support frame that are subject to corrosion in order to prevent corrosion.
Silicone on the jacks, but very infrequently as the coach is used frequently.
Chassis lube, whatever Speedco uses which I believe is a Mobil synthetic. Slack adjusters(brakes) high temp lube that the heavy truck shops use.
Here is a link to the Boeshield site. It is an awesome product:

Thanks I will look into the chain lube. I guess that lube does not attract dirt. I have a teflon lube for my mountain bike. I wonder if that would work as well. I see others like dry Silicone as well.
