I've disconnected the power steering lines several times when lowering
for transmission replacement, but cannot recall whether this is
the '06 Sonata. Check your paperwork from the
transmission replacement. If
there's a part number something like
npnsteerfd, then it was replaced.
I don't really think whether it was replaced during transmission
really the important question, though. How did the shop
determine you fluid was
breaking down? What tests did they run to
determine this? Don't be afraid to
ask these questions. What you're
likely to find is that the technician sees it
hasn't yet been done or that
the fluid is dark in color.
Shops recommend fluid flushes and replacements because they're high profit
items. Service advisors and technicians typically get financial incentives
beyond their typical pay for these items. Check your owner's manual.
see there's no maintenance interval for the power steering fluid.
it's really gross, there's *no* good reason to change it.
I don't think I've recommended this repair even once on any vehicle. I
say, however, that some older GM vehicles had some steering problems
flushing will help compensate for or help prevent, so it's not
true that this
service is *never* a good idea.
