Removed XREAS and installed springs and shocks from a 2019 4Runner that only had 1000km on them. XREAS was leaking ans had a terrible ride. I disconnected the hydraulic hoses at the banjo bolts not the check valves. One circuit had zero pressure inside and the other had almost none.
The install went quite well. One of the front top hats was stuck in the frame and had to be hammered a few times, and one of the rear shocks broke the shaft when I tried to remove it. Other than that it was easy. I used a cheap spring compressor and had no problems at all. Felt safe the whole time, not a hand grenade like most people talk about.
The ride is so much nicer. I just bought the truck a few months ago so I don't know what the XREAS setup was supposed to feel like new, but mine was making bumping noises over tiny cracks in the road. 2in lift in the front measured at the skid plate, and 1in at the back. This is exactly what I was going for and will suit me fine for a while. Hopefully I can get 32's under it with no real problems.

For anyone curious here are some pics of everything side by side. New springs have more coils but have the same free standing length. Thw spacer on top is .5in
The new rear springs were slightly taller than than original. The rear shocks surprised me being significantly longer. 7in travel on the new ones. I think 5100's are 8 something?
Camber seems fine but will take it for an alignment when I get new tires.
