Koni Yellow Stuck Adjuster
Has anyone ever experienced a stuck Koni Yellow shock adjuster? My front drivers side shock cannot be adjusted and the shock feels very soft (even softer than the softest setting). They were recently installed used and were fine for the first few days. After adjusting the height and reinstalling them yesterday, I noticed the problem. Does anyone know what the problem might be?

Re: Koni Yellow Stuck Adjuster (gsr-mike)
I recently bought used Koni Yellows off of ebay and the adjuster on one of the shocks was frozen (stuck). It would not turn at all. With the shocks off of the car, I would compress the shock and the piston would take close to ten minute to fully rebound on its own. Soon after I contacted CRX Lee, the koni tech, and he gave me this answer:
QUOTE CRX Lee:
/////////////////////
The adjuster could be stuck for two reasons: bottomed and internally damaged or just simply adjusted to a max setting and turned too hard to thread bind the adjuster. The fact that the shock comes out very, very slowly on that shock would give some evidence that it simply may be stuck at a max setting so I would expect it to take a very long time to extend under it's own gas pressure. My suggestion would be to try to carefully turn it clockwise towards soft and unstick the adjuster. it will either break free or break off depending on what has happened. If it breaksfree, you are good to go. If it breaks off, it was already stuck and damaged so there is no real loss there as it adds no effort if you have it serviced. To try to break it free, put a small crescent wrench (parallel jaw and not pliers what are not parallel) on the adjuster tab at the top. Hold the chrome rod in your hand and lightly bounce the wrench in a clockwise direction with your other hand. The adjuster rod is about a 14 inch long "J" hook that reaches all the way through the piston rod, pokes out the bottome them hooks back up to interact with the adjusting nut on the bottom then hooks back up to interact with the adjusting nut on the bottom side of the piston. It is this nut that gets stuck with a jammed adjuster. If you lightly bounce the adjuster rod, it will twist and wind up and try to loosen the nut. If you turn it too hard, too quickly, you can just snap the rod off so be carefull to bounce and turn it without overstraining it too much. If it can be possibly loosened, this will do it. If the nut can't be loosened then the rod would break anyway and doesn't matter. If you do break off the adjuster rod, l;et me know and I can likely sell you a single new one for a bit over $100 each. It will be chaper and faster for you to buy a new one than to have the current one taken apart, fixed and rebuilt and tested.

I used a crescent wrench and bounced it like he said, and it unstuck the adjuster. I can now turn it through its full range of adjustment and the piston rebounds very quickly when it is set to soft. I don't know if you're problem relates to mine, but good luck none the less.
