Technical Air into steering fluid

[TSAF]

Hey,
I changed my steering rack and after that, the fluid in the reservoir in bubbling.
Any ideas where to focus?

Have you tried going from lock to lock a few times with the cap off

Yes, its not trapped air, somewhere is comming from.
Mechanic that installed the rack, could not find it.

As rob0 says, turn from lock to lock took ages for mine to be bubble free, I had the engine running also

Well, 3 months of driving, is it enough lock to lock?

I would be thinking that something isn't right if after 3 months your getting air in the system.
When I fitted my reconditioned rack, I jacked up the front, just to get the wheels of the ground and turned lock to lock. Took a while as I suspect the new components in the rack would have oil on the surface trapping the air.

Probably NOT.

You have to turn to full lock one way, almost force and hold. You will hear the pump straining. Now you go the other way, hard over (you won't break anything). Repeat multiple times.

It can take quite some time/cycles.

If air is getting in then it will most probably be on the "draw" / pump inlet side.

Just for the record,

new steering pump solved the problem.
