I've copied this from a post I wrote on another forum. A lot of drivers seem to be having an issue where the shock adjuster O-ring is getting caught when they try to wind the adjuster down to add tension on the spring.
I believe it's the 13.95mm hole having a gap too large for the new smaller O-rings.
(Also, The exploded view of the '18 car also has the wrong O-ring part number on it)

Quote:
Having taken some old and new adjusters apart, the O-ring (despite having the same part number) is 1mm on the '18, they are 1.5mm on the previous cars.
The metal on the adjusters themselves has exactly the same dimensions, except for it's depth, 4mm on the '18, 4.75mm on previous cars.

The slot for the O-ring has also been reduced for the '18, but I think this is the important part, the diameter of the hole at the top of the adjuster is still the same, 13.95mm
I think the new slimmer O-ring is more easily able to get caught in the gap that exists between the main upper hole and the shock body, with the 1.5mm rings this is far more difficult.

It has to be said that although the first shock I tried to take apart tonight got very stiff, I still managed to remove the adjuster, the other three came apart easily.

Once I put all the adjusters back on they seem to have eased slightly, they are barely stiffer being wound downwards than they are being wound upwards.

If a running change needs to be made, I think it's the diameter of that top hole needs to be reduced to 13.5mm, should solve the trapped O-ring issue

Hey Skiddins...I wonder if anyone has found O-rings out in webland that work. My shocks are a lottery when I go to adjust them. Twice I'v had to take a shock off to be able to adjust it. I also took the orings out and thought I would try to run with out them but I'm not sure this is the way to go as they spin very easily.

I'm going to do some googling and see if I come up with anything. 8)
