It's pretty easy. Lift the back end, unscrew the tube, unbolt the accumulator, reverse procedure and repeat for the other side. The system is also self-bleeding.

Get out as much old fluid as possible from the tank, fill with fresh fluid, remove the return line, put the line into a catch can, run the engine with a helper bouncing the back end until clear fluid comes out, remember to top up the fluid as it's used from the tank, reconnect the return line, and top it up as it bleeds itself.
