During routine maintenace, I was told the dealership mechanic that my power steering boots were torn or ripped, as well as my cv boots. I am thinking to replace a the whole drive axles, not the boots alone. This should be more cost effective than boots alone, especially when one considers that joints may be compromised. When doing the install of axles, should I also replace the steering rack? Does the labor partially overlap enough that I can save a few bucks more than if I do them separately. I am tight on cash and my rack does not appear to be leaking any fluid, nor is my steering performance altered. Thanks in advance.
