Replacing LX470 AHC shocks

[NYC570]

I've searched and found a ton on info about the AHC system, how it works and how to maintain it. I also saw that a few people mentioned that they replaced their shocks, but I couldn't find any of the specifics on how to do it.

I actually own a LX570 but there's very little info about the AHC system in the 200 forum and since the system is fairly similar, I'm coming here for help. I'm not actually going to replace any of the shocks but to install spacers to do the sensor lift and try and keep the hydraulic pressures in check.
My main question is about the hydraulic line that attaches to the top of the shock. From what I've read on this forum, if you just unbolt it you'll be showered with hydraulic fluid. So how do you go about it? What have those of you that have replaced shocks done to prevent this from happening?

Thanks

The only reason you should replace an AHC shock is if you are ripping out the entire AHC system (I would not do that on a 570) or you are replacing a bad one. In this case you need to use the bleeder value to remove pressure, which you will then re tighten after. I just finished this job on a 470... it's not easy. Expect a least 4hrs for 1 shock. And, be prepared to get creative... I had to use a ratchet strap a few times to get through this project.
