According to my estimating program, this model has three hoses in the power steering system.
The pressure hose is $375.93
The return hose is 115.62
The supply hose is 96.11
Labor time required to replace them is 2.4 hours. Hourly labor charges vary from one shop to another, but using an average figure of $75/ hr this would be $180 in labor.
You will also need some fluid, which costs less than $5
So, a total average cost for replacing all the steering hoses would be around $773.00 plus tax on this model.
