Removing and Reinstalling Suspension Strut Accumulators on the Q45a
Written as if only the 4 strut accumulators are being removed.
1. Support the rear end on jack stands.
2. Remove the access panel on the right rear.
3. Carefully open the 2 brake bleeder screws on the hydraulic valve unit, one at a time, and release the system hydraulic pressure.
4. Close the bleeder screws when all the pressure is released.
5. Loosen the 3 bolts holding one of the rear accumulators until the unit can be moved freely. Then remove 2 of the bolts, carefully checking to ensure the residual pressure is not excessive. If the accumulator can be moved by hand back on its seat, remove the remaining bolt, and slowly lift the accumulator off the seat and central pipe fitting. Some oil may spray and drip out. The accumulator will be full of oil so be prepared with a drip pan or container to catch the 4-6 oz of oil.
6. Reinstall the recharged accumulator right away. Rotate the accumulator so the heavy weld near the bottom faces out and does not interfere with the base. Tighten the bolts to 10 -15 ft-pounds.
7. Repeat for the other side.
8. Reinstall access panel.
9. Remove rear jack stands and move them to the front.
10. Remove the plastic half rings on the top of each front strut.
11. Lift up the rubber cap and slide it out of the way to expose the brake bleeder screws. Attach a rubber hose to the brake bleeder screw and carefully open them, one at a time, and release the system hydraulic pressure.
12. Close the bleeder screws when all the pressure is released.
13. Remove and reinstall the front units as for the rear
14. Remove jack stands.
15. Add enough fresh Active Suspension Fluid (Nissan Only please) to replace all the fluid bled out and spilled.
16. Start the car and check for leaks, top up the reservoir.
