I noticed a low frequency whine the last couple of times after exiting
the highway. The whine is loudest after exiting the off ramp then
slowly dissipates in normal city traffic speeds in about 15 minutes.
The whine is RPM dependent. Any ideas?

Are you sure it's not the power steering pump? The one in my 02 Voyager is
pretty noisy...and it only has 58k miles on it. It is most noticeable after
coming to a stop after about 2.5 miles from home after running at 55mph on a
cold morning. As it warms more it seems to go away. If you are at a stop
when you are hearing the noise and turn the wheel just slightly, does the
wine sound lounder and more like a groan?

It definitely is the power steering pump. Got off the highway the
other day and came up to a stop light. The low frequency rpm dependent
whine was there. I happened to turn the wheel and the whine changed
with every turn of the wheel. I'm glad I know what it is; now is this
a sign of the pump going south? The 2006 caravan is pretty tight. It
might be a nightmare getting it out. Thanks for your suggestion.

Try changing the p.s. fluid - especially if it came from the factory
with something other than ATF+4 and is now Ok'd for use with ATF+4 (see
below). If that is the case, no guarantees, but this would not be the
first time I would have read of replacing the fluid and switching to
ATF+4 solving a noisy p.s. pump problem.

Check out TSB No. 19-005-03. It tells what fluid came in what years of
Chrysler vehicles, and which ones are now recommended for ATF+4 as the
service fluid - or if you post what year your Caravan is and what the
build date is, I'll tell you what the TSB says about it.

Hi Bill,

It is a 2006 Caravan; manufacture date 04-06. I spoke with a friend
today who mentioned that there was a problem with the PS resovoir
itself. Something about a filter that would get clogged. I don't know
if there is any truth to this though.

Oh - 2006 - definitely came with ATF+4, which of course is the service
fluid for it too. Is he saying that the problem with the
reservoir/filter is a common problem with those, or did he look at yours
and say that he sees that problem on yours?

Is there any warranty left?

Please keep us posted...at least me. :-) I've got an 02 Voyager with the
same symptoms. I've been corresponding with Bill off list and he suggested
changing the fluid, which I think I'm going to try - unless you find out
something more about this filter.

Thanks,

Wesley

I've got R and R instructions for the pump but its for a 2004 with 3.8 so
I'm not sure its the same..........
