Infiniti QX80 Hydraulic suspension replacement and bleeding.
Please dont judge, this video is not to promote my repair shop (I don't have any, I'm not an auto mechanic), just sharing my experience. Making mistakes, not doing right...English not good... but at least my cur is running, and running great :)
Ite really hard to find information about this car, many auto repair shops have no clue how to do it and don't want to do it at all. Here in New York the Nissan dealer didn't want to help, the Infiniti dealer said get ready $800 just for bleeding !
So, 2 rear air hydraulic shocks from ebay $350 (if you want to replace only one side make sure you order the correct side !! front left/right and rear left/right are different ! )
Hydraulic fluid 2 liters got from CHF 11S Hydraulic System Fluid

1 Pump fluid into the pump.
2 Attach connector
3 open 3 top valves 2 circles
4 take off the rear driver side wheel
You have to start from the rear left strut to bleed
5 Always keep pressure in the pump and make sure the bottle or canister with fluid is always full so it will not get inside. If the released fluid is clean you can use it again.
6 to bleed other struts, not necessary to remove the wheels, it just doesn't have to touch the ground.
5 after bleeding tall of the jack
This system is completely independent. No electrical components, no codes..etc.
After pressure released I took a test drive to see how it feels ... it's horrible, falling to the sides when turn, feel all bumps ..etc
