I went ahead and attempted to repair the manual adjustment knobs on my RS9000X Rancho adjustable shocks. Several forum members were kind enough to reply to me earlier topic HERE.

To my disappointment, the two rear shock adjustment capabilities are seized. The adjustment knob is not water tight and has allowed water to enter the mechanism and both are severely corroded.

Despite that fact that one knob could be moved from #1 setting to #8 setting (and the other only went to #6 setting) the shocks are corroded on a high setting, (which I suppose is good news). When I removed the knobs, it was clear that the internal adjustment piston has siezed. However, the knobs still turn which have made me think that I was actually adjusting them.

I'll have to admit that I have noticed a stiffer ride in the last month since the camper has been off the truck, so I should have assumed something was wrong.

I removed and inspected the knobs on all four shocks. The rear ones are both shot, but the front ones are still operational... I think I caught them just in time and have cleaned them out.

Here are the photos:

1. Kinda rusty down there.

2. Corrosion on worst shock. Piston is stuck in place.

3. Second bad shock, even after cleaning etc. the piston is shot.

So, I would suggest others who own Ranchos may not be aware that their shocks are not functioning in the correct manner. Perhaps maintainance proceedures on the adjustment knobs might include:

1. Silicone the screws and the gasket when first installed to make future removal easier. I had a heck of a time cleaning the screws to allow the allen key to fit, for removal.

2. Come up with some way to avoid water, road salt, grime, etc from coming into contact with adjustment knob.

3. Annual or semi-annual removal of rear knobs to inspect, clean, and ensure water tightness.

Now it's off to the Rancho website again to pursue warranty replacement, albiet I will have to likely pay to have the shocks re-installed (if replaced).

I had two 9000's do the same thing on our 1996 F-250.

Keep us posted on whether Rancho will replace them under warranty.

These shocks are less than 3 years old. And the truck only sees less than 10,000 miles per year on the road. I wash the truck off after every trip and make sure to rinse off the shocks.

The roads here are salted when there is ice/snow, but in the last 3 winters I'll bet the truck has only seen 10 days on the road in such conditions. I was amazed at how fast the shocks rusted. [emoticon]

How old are those Ranchos? They look like the shocks on the Titanic. That's one thing I never liked about Ranchos, they rust real bad, real fast. [emoticon]

Hi: They just replaced mine for the same reason. Having to replace them is just a PIA, so I took my new ones apart and filled the void with fluid film. Don't know if this will extend there life but it can't hurt..

I wonder if it would help to smear them with grease every once in a while.......TD
