2004 Volvo dp SM power steering issues
Yesterday, 11:40 PM
Steering is stiff at all speeds when minimal pressure is applied to wheel. With a hard jerk to wheel, power assist kicks in.
Have done or tested the following:
Replaced steering cable
Verified cable and actuator move freely
Replaced fluid
Pump is quiet and works perfect once the actuator engages the ram (both directions)
Other observations:
When engine is off actuator slides freely back and forth from stop to stop (about ? inch)
When engine is started actuator returns to center position and will only move about 1/8 inch
If manual pressure is applied to actuator in either direction the power assist will engage or
If you jerk the wheel the power assist will kick in.
These conditions exist at idle speed, neutral or while on plane. It appears that the actuator requires more force than necessary to engage. I have been to a Volvo dealer and they are not sure if it is the pump or actuator and could not give quote. Can you tell me with the information provided if I have a bad actuator or pump? Thank you for your help
