Unfortunately not. Sealed units. Buy another OEM shock, which can fail again or go aftermarket. Many here have gone with Scott Ahlman's Ohlins which are rebuildable and adjustable.
No the stock shock is sealed. It appears the leaking shocks heavily happen on lower mileage cars. I believe it happens when the car sits for long periods and the shaft seal dries out and then the next time it is driven damages the seal.
Thanks Scott. I try to get mine out for a few miles every couple of weeks. Guess even that is not enough driving. I just replaced it with an OEM shock at $502. Would love to install your suspension system, but no one close that I would trust to install it. Maybe someday the stars will align and I'll be where it can be done.
