Problem with Subaru Legacy 1995 4WD

The car is a Station Subaru Legacy 1995 4WD 2,000 CC, the problem is that it entered a workshop because the address was very hard (as mechanics) and repaired the steering box, the bruises were changed to both sides, they ruined calipers and change of pills. With all that repaired he left the workshop but the address is hard, a little better than before, but when the address does not come back.
The consultation is: what could be the problem if the repairs that the mechanic said.
The manual manual is in the manual section and I have it.

I will appreciate your help not to keep spending without a solution.

Thank you.

The address box may be well, but you would have to try the pressure delivered by the hydrahulic pump to it to rule out that you have a problem in the discharge valve (eg) the pump, and deliver less pressure from which it should and is why it remains as hard. In any case; The fact that the address does not return or return when turning is already alignment (parallel). Greetings!!
