My 2000 LX470 with about 160,000 miles lost it's suspension fluid, via leaks through the shocks, accumulator, and rusty lines. LEXUS wanted about $8700 to fully repair....and that did not include a new pump or other leveling switches which were working. I did some research and I just converted to a Toyota 100 land Cruiser type suspension system for about $1,700 installed. The ride is great, but I lost the rise and lower feature of course. There are a few kits on the market, but I choose Strut Master mainly because my mechanic had good luck with them in the past. My kit was $500, and labor to install was $1200, which included a new alignment. The top of the rear shocks are a !Removed! to get off, so my mechanic cut a small hole in the floor above, and patched it after the install, which is hidden under the mats anyway. The kit has 4 shocks and two stronger rear coil springs to simulate the Landcruiser. I highly recommend this conversion as once the hydraulic suspension begins to go, you could spend thousands to repair. The original system has so many parts that can fail so I highly recommend the conversion. My 17 year old LX470 is probally only worth $8,000 now, so I am not concerned about any loss in value from the conversion. And I never have to worry about expensive repairs on the suspension ever again.
