Hi there

Had my BRAND NEW 2010 GT500 for a month now.

I did and have always noticed a "slight" axle whine "from behind" when driving 5mph to 10mph. After that, no sound.

Anyone else having this issue?

Found some links, am i onto something?

Maybe this can solve my problem?

Hope you can help me out.

You actually go 5-10mph in your GT 500? J/K :)

Yes in my garage..

Im kind of a perfectionist person. I notice EVERYTHING. And hate unusual sounds etc. :)

Ford makes quiet cars, too. We have a MKX and it's like a friggin' tomb.

so i assume it is not possible to get any help in here?

It's under warranty. Have them fix it. Don't be dicking around with friction modifier. Then it's on YOUR dime.

If you have any aftermarket suspension components, you're gonna hear noise.

If you're completely stock, it should be fairly quiet.

I put on an off road x-pipe and the axle whine went away.

Not to hijack but I just started to notice axle whine on my 08 with about 11k on the clock. It's not loud but noticeable if I turn the radio off at highway speeds. Cause for concern?

Seriously though, it is a Mustang. Both of my manuals have some axle noise. My auto does NOT though.

Never experienced axle noise/whine in my previous three mustangs, all manual. I'm not complaining, just making sure it's not an issue.

i will soon put the roush exhaust on my gt500. its on my mod list :D

I dont have any warranty coz its been imported to denmark :(

I also notice that groan/whine when making "tight" turns to the left like described in the links i posted first time. They have added the friction modifier, and no more noises...

so maybe i should try it??

I have the same problem, its embarrassing when going through a parking lot with people around. The thought of the amount of money I paid for this car and it make a sound like that. It give the chevy and challenger crowed something to laugh about....
I have had it to to dealer several times about this and finely the service manager heard it while in the car with me. But after leaving it a day with them, they couldn't find the problem. No other service member could hear it either. The sound was there when it was stock and the sound was there after x-pipe and suspension was up graded. 2010 GT 500 7,500 miles bought in January.
By the way I don't need any replies from non daily drivers. My car doesn't make a sound either when it sets in the garage. And no I don't like to lessen to the radio to cover the sound. I enjoy lessening to the car when driving..

Dude take it easy. This is not like other forums where guys attack each other.
Sometimes when guys post things they are just goofing around.:lookaround:

I'd try one more dealer and see what they find. This is because your still in warranty, if you weren't I'd say try the friction modifier in the rear end, but then it's on your dime.

so maybe i should try it??I had the traction-lok clutch pack moan/groan when turning to the left. At first it was only after the trip home and then manoevering the back laneways. At 16K km the dealer couldn't reproduce it. Started becoming more frequent though and louder. Next trip to the dealer at 24K km they were able to hear it and added the friction modifier and the noise is now gone.
I still have a little gear whine at higher speed though...different issue and probably still within "normal characteristics for the car" as Ford likes to put it.

Yea your are right; but like I was saying I never thought of spending this much money for a car. This GT500 2010 and the GT 2010 I traded in, have been in the shop one too many times.
I have owned a Galaxy 500, Explorer, Escorts, Cougar, Elite, Probe all driven to 100,000+ miles. They never had problems I have had with GT500 / GT with less then 10,000 miles. All to have the dealership to look at you like your making things up.

This is one of several reasons I still haven't purchased a GT 500. There just seem to be too many issues for a car in this price range. Yes, I know it is a "performance" car, but for the money, there are many "performance" cars that don't have issues.

Dont think you will find a perfect car out there. The Mustang is the coolest car on earth, and these little "issues", that i don't really see as issues is allright to have for a mechanical car. Its not electronically car and quite like BMWs, Benzs or Audis. Where even the exhaust is quite too.. Its a mechanical machine, so yes, you will hear noises and so.

This is my second Mustang, and these stuff won't prevent me from buying Mustangs whole my life. It's a true American classic, and i just enjoy it every day i can with the sun out here in borring rainy Denmark!

I have an 09 with 15,000 miles. The car...clutch and all....runs fine....

After I had my suspension mods I picked up a little noise in the passenger rear wheel, or so it sounds, I'll have them check it when I get the rear sway bar put on next weeki. Good to know its normal to pick up new noises. I figured as much.

My car makes the noise during low speed turns are pulling into parking spaces. It's pretty embarrasing and a noise my 05 GT never made. I've never had a car that had so many issues like mine has.

Why are you on this forum? The only thing you do on here is flame the gt500 owners. Is it penis envy or what? If you don't like the 500's don't go away mad just go away.

P.S. i can only guess what the sj stands for.:thefinger:

GT1MYZ:
I had the same issue on my 08 gt500 also., Took it to the dealer and they did basically a overhaul on the rear diff. Mine was realy loud under load, if backed off noise would stop. THis was done this year and I had about 5k on it when it was done. Now have no noise at all.

I just started getting this noise on my 2011. Very similar to 08svt- noise under load and it goes away when I back off. I'm taking it in to have it looked at for sure.

I have an 07 Vert with 10K and no noise just like Melissa's 09. Maybe the verts are just built better!:thinkerg:

i know i am going to regret this but here goes. my car was great the day i got it and is even better today. never even a hic up. tons of mods. i love this car more than any car i have ever owned.

Thanks guys. Guess I'll let the dealer take a look.

I just noticed this while turning around in a parking lot, I will have the dealer check it out also.

The dealer I took mine to did add some fluid but then said there is a service report out that said the sounds are normal. After adding more fluid it had not been as loud as it was.

I am bringing mine in to the Ford dealer tomorrow morning for this issue. Mine is pretty loud and occurs in parking lots and all turns below 20 mph on the street. I will let you guys know how I make out.

Yes the GT500 has some issues and each model year Ford is correcting these issues and performing TSB's to the previous model years. I know a few people with various makes of performance cars and they all gripe about their cars quirks and issues.

All I can say is this that my GT500 has spent allot less time at the dealership than my brother-in-law's 2010 BMW M3.

The SVT Mechanic added some friction modifier and it is not as loud as it was. He said to drive it a few hundred miles and the noise should get less. If it doesn't and continues to be an issue then bring it back and they will change the clutch packs.

I got my 2010 at the end of May. Noticed the whine in the 3000 mile range. By 6500, it was louder and I'd had enough of it. Took it to a large dealer with two GT500's on their lot. Took both a service advisor and salesperson for a parking lot experience and both agreed to the level of the whine being too high. In for service appointment, the mechanic refuses to do anything claiming it is normal per Ford's TSB writeup. I take it to a much smaller local dealer. They replace the clutch packs without any discussion. The whine was immediately gone. I'm approaching 10,000 miles now and still no noise. Shop around for a dealer that will do the right thing from the start.

I have 2700 miles on my 11 and just got it back from the dealer while I wait for the parts to come in. The service guy said that they were replacing parts in the rear diff and tighten up the suspension.??? Just when I got mine back my wifes 11started making the same noise. This is crazy but atleast the dealership is going to fix it.

I have about 450 miles on my 2011, no rear axle whine, no gear grinding (I love my clutch so soft and effortless, and dont mind driving in traffic). I dont know if just blessed, or if its all waiting to go wrong at once. At how many miles do you guys start to hear axle whine?

Mine started around 2k miles. After the friction modifier was added the whine is going away, almost completely gone.

First noticed mine around 1200 miles. Dealer checked it out and gave me a bulletin on it, said it was normal duo to the high performance rear. I poster the their wording on another post about it.

What did the add the friction modifier to?

you gotta proof read buddy. sometimes it's hard to understand your post.

Yes I see what you mean, that seams to happen when I use the Ipad. Sorry Pal.

no problem. your just making me use my brain more..lol

:zlurking:

I am looking into buying a GT500 myself. I expect problems. Why? Any performance car is going to have some issues. This is probably true because money is spent on performance and not in perfection. Also, performance parts tend to be designed to be strong to take the “performance” What does that mean? It means that transmissions have stronger gears, bigger, bulkier, perhaps cut in different angles, etc., therefore they make noise but can handle way more torque. The lower the gear ratio in the rear (3.55, 3.73, 4.10, etc) the more likely they are to make noise. Then add to that a limited-slip clutch pack, it all makes noise, but give you the performance you want. The new Shelby carbon ceramic (or is it carbon fiber?) limited slip clutch pack in the rear is far superior in the traction bias, but is quite noisy. Then “suspend” all that with non-forgiving hard bushings, which will conduct all of these noises right into the car’s structure. You’ll hear noises. Super soft rubber bushings take performance away, but also isolate noises from the drivetrain. An aftermarket shifter in a Corvette lets you hear the trans and also transfers heat to the point of burning your hand, if you have a metal shift knob! But shifts much better than stock!

Back to the problems aspect. I have had a few Corvettes in the past. Not one of them was trouble free. The past one had the drivetrain removed at 5000 miles, because of a failed rear main seal that seemed to have exploded and the engine was vomiting oil. All of them seeped oil anyway, all of them had many small issues, including gear noise, etc. The fix for the gear noise in the rear was a different fluid with friction modifier (slip agent) added in the fluid already) That was the third recall for rear noise.

I know a Ferrari owner that paid $244,000 for his car. It’s in the shop every season with problems. All minor stuff, but nonetheless, problems.

The Mustang is a cheap car in comparison to the performance you get. So it will have its issues.

Performance cars are always troublesome in some way in my experience. Just for the record, it gets on my nerves too and I don’t like it, but I am learning that if I want fun, it will have a cost.

You can buy a Honda or Acura and have a super reliable car. But it won’t have a big V8 and the performance you we all want.

SJ buy gxsr you'll beat any car out there and it's in your price range.

Thumbs up. Nice post. :) Like i also wrote, if you want a quiet and perfect car go buy a benz, audi or bmw. I read about the lambos, that they are also spending pretty much time in the workshops coz of the roads they drive on. These car are not meant to be driven on bumpy and bad roads. We have them alot here in Scandinavia. Somewhere better than others..

We'll im glad i am not having the whine problem myself. Since its snowing here and the car is all jacked up, i will have it looked at it, next year when the weather gets better. Probably will go buy some friction modifier and tell the the mustang mechanic about the problem. You cant really go to a ford dealer here in Europe, coz they do not sell the big ass F-150, mustangs and shelbys here. (Im so much in the wrong country haha) And if i did go to a ford dealer, i wouldnt feel safe.

Benz, Audi, or BMW.................for perfect and quiet...........lol

Brother-in-laws 2010 BMW M3 in the shop for non-maintenance issues more then the GT500. Friend at work has Audi A6 in the shop almost once a month for electrical, ABS or check engine light. Friend at work with Benz SUV ML350 constantly bitchin about how many times her car has been in the shop and can't wait for lease to be over. Those are just a few examples.

Plus the maintenance costs on German vehicles are high in comparison to American vehicles.

Go on any Japanese, American, German...........etc performance car forum and you will find owners complaining about issues with their vehicles.
