I brought my X-terra in to have the the power steering looked at, there was a leak and you could hear
some noise. They did some diagnostics, couldn't find a leak, so they topped off the fluid and added dye to pinpoint the leak. Brought it back 10 days and nothing significant was found and they said to keep and eye on it.
I already had another shop tell me they "Determined" that my PS pump was bad.
I will be taking my vehicle to the kar shop from now on and would highly recommend them!
