Last year, I bought a 2005 Volvo S60 for my wife to drive to her job.
The car had 103,000 miles on the clock, so a few weeks ago, I installed a new timing belt, tensioner, idle pulley, and water pump. In order to complete the installation, it was necessary to pull the power steering fluid reservoir off to the side to gain the clearance to remove the timing belt. The timing belt installation was completed without any serious incidents.
I was also advised by a mechanic that the car needs to have new lower control arms on the front, as well as new joints. He said that the joints are "slinging grease". I don't even know exactly what he meant by that.
I inspected the hoses on the power steering fluid reservoir as best I could, but I can't see that it's leaking; I really have not idea how the car is losing its power steering fluid.
I have refilled the car's power steering fluid twice in the last week. What is the best course of action to take to find the problem and get it fixed?
