Three problems related to power steering fluid have been reported for the 2004 Jeep Liberty.
While driving my 2004 Jeep Liberty I lost power steering. I was able to pull over and stop without incident. My steering rack and a power steering pressure line started leaking a lot of fluid resulting in loss of steering. I have since learned that this is a familiar problem to Chrysler/Jeep but there is no recall. Sudden loss of steering is a serious problem and a recall should be considered.
I have had repeated problems with my 2004 Liberty power steering. It appears that in very cold conditions the fluid leaks, maybe a shrinking gasket or seal? a seeping power steering line? the leak is at the fitting where it goes into the pump. It appears that the pressure from the pump is overpowering the o-ring in this fitting. Unfortunately the leak went unnoticed until the system went dry.
Noticed that one power steering hose was pressing up against the plastic fan shroud. Inspected the hose and found that sharp edge of the fan shroud was cutting into the hose. The hose developed a small leak of power steering fluid. Had car into dealer for an oil change and asked the technician to inspect the hose. He confirmed that the shroud had cut into the hose. The hose was replaced and correctly located away from the shroud. This was a factory error in that the hose should not had been installed up against the plastic fan shroud. Undetected the end result would have been an unexpected rupture of the hose and loss of power steering fluid,and steering ability.
