Chrysler: Intrepid (99) wheel noise - CV joints?

consider "morning sickness". you will need a new rack and pinion soon.
for details search for morning sickness.

steerign will heavy at the start ups and you might feel some force pulses.
when it is hot, it does not cause any problems. it becomes more obvious at
lover speeds because you need more power at lover speeds.

It might be loose belt or low fluid level also.

good luck.

"Morning sickness" has a symptom of stiff steering, which is not my case at
all. In fact the steering if quite normal and takes little effort. The
steering fluid was changed (by dealer) about 5000 miles ago with no problems
noted. So I'm not convinced that this is the problem. Any other ideas?

Sounds like classic belt squeal, which can be very temperature dependent
(tend to do ti more when cold). Also, the biggest load on the belt is
when the car is sitting still or moving very slowly and you're turning
the wheels (steering wheel). Belt either needs to be replaced or simply
tightened.

I know the belts on certain (all?) LH engines do not have automatic
tensioners, so they do need manual adjustment and proper tensioning.

If the noise is mostly dependent on turning the steering wheel and not
on the tires/wheels rolling (which I think is what you were saying),
then it's definitely *not* CV joints or brake rotors. If it *IS*
related to the tires rolling at low speeds, it could be the front brake
pad tell-tales telling you that your pads are at end of life (they're
intentionally designed to squeal at that point). From your description,
I'm betting on thbe belts.

Thanks Bill. The noise only happens when the car is moving, I haven't
noticed it when applying brakes. Unfortunately it doesn't happen everytime,
but I think it is coming from the front right side of the vehicle. I'll
have them measure the belt tension. Good news for the CV joints is that
there is no clunk-clunk or anything like that.

Greg - Now it's leaning more towards brakes rather than belts (because
you say it only happens when moving). If the pad wear tell-tales are
sounding off, often they will get quiet when the brakes are applied -
only sounding when either not applied or very lightly applied. It can
be, and often is, very intermitent at first, and can be dependent on
turning or not turning because we're talking about a thin metal piece
just starting to scrape the rotor to make the intentional squealing
noise as the pads wear (at end of life) - IOW a movement of the rotor
only a few ten thousandths of an inch one way or the other due to
axle/bearing/rotor flexing from sideways stresses from turning the
vehicle can mean the difference of no scraping contact (no noise), light
scraping contact (squealing noise), or hard scraping contact (possibly
no noise). As they wear even further, you may find that they will make
noise even when not turning. I think you will find that the pads need
replacing and are trying to tell you so.

I hope this makes sense. (BTW - the rear brakes on the LH vehicles do
not have the tell-tales.)

It makes sense, but there appears to be quite a bit of life left in the front
pads, at least from what I can see from the outside of the wheels. How much of the
pad should be visible when the wear tell tales become audible? There's no rhyme
or reason as to when the squeaking occurs, although it happens more when first
using after being parked for a while. The squeaking tends to be when steering
hard left or hard right and sounds almost like an annoying squeaking door hinge.
Thanks!


Here are the brake sounds diagnostics
-------------------------------------
Condition: DISC BRAKE CHIRP
-
Possible Cause: 1. Excessive brake rotor runout.
Correction 1. Follow brake rotor diagnosis and testing. Correct as necessary.
-
Possible Cause 2. Lack of lubricant on brake caliper slides.
Correction 2. Lubricate brake caliper slides.
-------------------------------------
Condition DISC BRAKE RATTLE OR CLUNK
-
Possible Cause 1. Broken or missing anti-rattle spring clips or rail shims on
shoes.
Correction 1. Replace brake shoes, spring clips or rail shims as applicable.
-
Possible Cause 2. Caliper guide pins loose.
Correction 2. Tighten guide pins.
----------------------------------------------
Condition: DISC BRAKE SQUEAK AT LOW SPEED (WHILE APPLYING LIGHT BRAKE PEDAL
EFFORT)
-
Possible Cause 1. Brake shoe linings.
Correction 1. Replace brake shoes.
------------------------------------------------
SCRAPING (METAL-TOMETAL).
Possible Cause 1. Foreign object interference with brakes.
Correction 1. Inspect brakes and remove foreign object.
-
Possible Cause 2. Brake shoes worn out.
Correction 2. Replace brake shoes. Inspect rotors. Reface or replace as necessary.

I don't know the spec. for minimum pad material thickness, but it's
something on the order of 3/32" (2.5mm). If they're way thicker than
that, then it's not the warnings.

Sometimes the bearings can make squeaking noises like that too (sorry to
be all over the map on this - first belts, then brakes, now bearings).
It's hard to troubleshoot something like this without being there. If
the pads still have some meat on them, then I'd not worry about it until
some more certain and steady symptoms develop (may never happen - may go
away completely on their own).

It may be some contamination (grit) on the pads in combination with a
little drag. Possibly some day you will have some brake work done (new
pads and rotors), and it will go away. Make sure calipers move easily
on their slides, pistons are not stuck, and pads are installed
correctly.

Hmm, the plot thickens. I will take a casual look at it this weekend. Dealer last
week said they didn't find anything out of the ordinary, but couldn't take it on the
road and listen with windows open due to heavy rains. The noises are coming
more frequent. Still more often after being parked for a while, but not always.
The damned thing is that today I heard one pitch of squeak turning left and
another pitch, more creaky when turning right! So whatever is
making the noise sings in two keys. Go figure. I would love it to be some dirt
in the brakes and I plan to wash them this weekend as well. Thanks, Bill!
