Good afternoon,

Can you post me some pictures?

Repaired the boost? You should have replaced it. There is about 800-1000 pounds of pressure in that unit.

How did you bleed the booster? Since it is part of the power steering system, it has to be bled.

I attached the procedure below for you as well as the brake bleeding as well.

1. Fill pump fluid reservoir to proper level and let fluid settle for at least two minutes.
2. Start and run engine for a few seconds. Do not turn steering wheel.
3. Turn engine off. Check fluid level, add fluid if necessary.
4. Repeat above procedure until fluid level remains constant after running engine.
5. Raise front end of vehicle so wheels are off ground.
6. Start engine. Slowly turn steering wheel in both directions, lightly contacting wheel stops.
7. Add power steering fluid, if necessary.
8. Lower vehicle and turn steering wheel slowly from lock to lock.
9. Stop engine. Check fluid level and refill as required.
10. If fluid is extremely foamy, allow vehicle to stand a few minutes and repeat above procedure. For additional bleed procedures, refer to Fig. 2.

Okay. Can you elaborate on what you did to repair these components? Clearly they are related and it sounds like the accumulator is at fault but that could change depending on what you have done to it.

I attached the info about this system and the likely cause of this for your review. Let us know the detail about the repairs and we can go from there. Thanks
