Why is power steering air so hard to bleed out?
Purging air from power steering lines after a repair is physically exhausting and repetitive, requiring fast sweeps of the steering wheel. Even after working hard to bleed the system, trapped air causes persistent bubbles in the reservoir and leaves the steering tight and whiny.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Turning the steering wheel back and forth 20 times with the front end jacked up, both with the engine off and on.
- 2Keep the reservoir cap off and run the engine while turning the steering wheel fully back and forth to bleed out trapped air bubbles.
