My Lincoln has been making this noise since I bought it last year with 35000
miles. The dealer told me it was the tires (bought 2 new tires). The
dealer has since had the car several times but has not been able to find the
problem. I can hear the noise inside the car with the AC and radio on. The
noise changes pitch as the speed of the car changes (not the engine speed),
is rhythmic and just loud enough to get your attention. It does not come
and go at different speeds From the driver's position it seems to come from
the front right.
Can anyone help?
Take the tech that will work on the car for a ride..... be absolutely sure
he hears the sound..... be absolutely sure he is a tech and not just some
damned Yankee with a toolbox (you guys really need to get some sort of
proficiency regulation going).
See if you can find a tech or shop that displays certifications proudly - it
is the man (or woman) that is proud of their labours you are looking for. Be
aware that they will charge accordingly.
I have taken the dealer service manager and his technician for a ride and
they heard the noise. They have changed tires, rims, front end parts and
every time the noise is still there. The last time they returned the car
they said they ere going to contact the manufacturer. We didn't hear back,
my wife called Ford PR dept. and was told Ford has decided the noise is
normal and not a defect. I will call the dealer this week to confirm this.
All work has been done under warranty except buying tires.
After the warranty expires, I would take it to an independent garage and ask
them. Remember, you had the complaint during the warranty period. If a cause
is found after the warranty expires, they still have to fix it.
At this distance it's hard to make even an educated guess. With info coming
in dribs and drabs I'm sure to repeat many things that have been tried or
I have come across sealed front wheel bearings that DIDN'T exhibit any
symptoms that didn't feel or sound real good once the rotors are off of
them. Our shop has also seen a couple of CVs or GMs that showed insufficient
hardening of the bearing surface on the rear axles... noisey but certainly
not a "tire" sound. Having said that, I have the nagging "semi-memory" (it's
an old fart thing) that these are IRS but there remains the chance for
noises to 'telegraph'.
TSB 01-21-07 deals with a moaning noise during light acceleration at highway
speeds but I haven't enough information to decide if this might be
applicable or not. One thing that I will mention is tire pressures and
direction of rotation..... recommended tire pressures are on the VIN decal
at the drivers door (too many folks inflate the tires to the pressure marked
on the sidewall) and, in the case of directional tires, other folks don't
notice the arrows.
You might want to try another dealer, maybe in another town. A large
Lincoln dealer may have someone who can recognize the noise right away. You
might even ask if they have a NVH (noise, vibration, harshness) specialist.
Ford used to have a special certification for that.
Keep us informed...
Ford still does..... odd as it may sound NVH certification and Basic
Electronic certifications are pre-requisites for all the other
certifications. It's neither easy nor extremely hard to pass cerification
but a tech needs use his/her head and the knowledge given (sadly missing in
all of todays society).
Sorry I haven't gotten back with more info on what has been done but I
haven't been able to get the service people to return my call. I will go
there tomorrow and try to get more information. Hawaii is a small state and
this dealer is the only game in town.
