whining rear end?

[khc3]

the few times I have gone wot (i know, i drive like a granny), I've heard a whining sound coming from the back of tthe car, obviously from the rear end. Is this normal?

yes, everything stock.

I would suggest going to the dealer. There have been some comments on the board regarding the occational axle bearing problem.

Good luck.

Cabbage usually does it to me.

Does the pitch or volume of the whine change with engine or vehicle speed? If it changes with vehicle speed, it could either be differential gears or axle bearings. If it changes with engine speed, it may be trans or engine related and just sound like its coming from the rear. 8.8" axles are know to have poor bearings - at least on Mustangs. Thats my guesses.

I had the same problem, the issue was resolved after I replaced the rear transmission seal.

Drive to Team Ford of Marietta...ask for Scott Levin...let him drive/hear the noise...consider yourself fixed when he gets done.

Bada bing, bada boom.

Mine starts to whine at about 5000rpm-almost sounds like a S/C. I think it is common and transmission related from what some of the other guys have posted???? :confused:

Todd, where is Team Ford located in Marietta? I took mycar to Billy Howell in Cumming (5 mins from my house), but I'm not quite sure about them. They are an SVT dealer; does that mean anything? I've read your raves about Team Ford, which means a lot to me, but I dread driving to Marietta, especially if I'd have to leave my car.

One last thing: if they have to work on the rear end on a warranty/TSB deal, woukd they be cool with putting in 4.10's?

Thanksagain for all the help, you guys are great!

[JamesHecker]

I get the same winding sound after wot and I have had the rear bearings replaced under the tsb and have 4:10's.

I remember seeing a thread on this before, but I can't recall what the consensus was.

FYI, put Susan's 300A in for the rear end whine. Got so bad you could bearly talk and hear. Brought a copy if the axle Silent Recall from the blue oval site with me. They took it in with no qualms at all, and of course, it was the axle bearing and axle. Now, the only problem is the axles are on back-back order, due to the failures. They are now being shipped directly from the vendor as they get made. Car has been in the shop since Monday, and there is no set date for the part to be shipped other than "any day now". So if you are going to put your car in to have the rear end checked, see if they will get an axle in first (or check availability) so you don't sit in the shop. Word to the wise.

I know several whining rear ends!!:lol:

People whine after hearing my rear end!:eek:

NORMAL! The noise you are hearing under hard accel at higher rpm's is coming from the transmission. I believe it is the pump. Mine has done this since day one and it is not indicative of a problem (I think it sounds kind of cool). This was a common issue about a year ago when the car was newer. Now those of us that have had them a while have become used to it. If it were a rear differential issue it would probably be consistent either on or off the gas at highway cruise. If it were an axle issue it would be speed depedndent and not matter if you were on or off the gas.

First, let me say that describing foul or odd noise here is very frustrating. What you hear, and how you decribe it, usually turn out to be two different sounds and two different causes. It's a shame we can't teach our ears to type, eh? I suffer this same frustration when I get involved in discussions of exhaust volume and tone. It's an impossible task, I wonder why we even try.

That said, we have tried again, and frdwrnch is right. I hear this short lived whine, or "wind down" on a regular basis. I can cause it to occur with a burn-out. I lock the tranny in 1st gear, brake up and add throttle. I spin and put on an impressive display, maybe dig a matched set of ruts in the blacktop too. Once I jump off the throttle, I hear this WWAAAahhh wind down.

If this is what you hear after your WOT adventure, it's the front pump inside the tranny. No worries mate, your MM was pumped to drive hard into the next gear, and you backed out. Kind of like falling asleep while your Lady "changes into something more comfortable."

A constant whine that increases/decreases in volume and pitch along with your forward speed, is rear end bearing noise. It will remain constant with the forward movement of the car and you can change pitch and volume by adjusting your speed. Bearing noise that comes from inside the tranny will appear only under power, even light coasting power, but go away when you let off the gas. Help you any?

I have the same problem started to notice last week, now it's driving me nut, Where can I get a copy of this recall notice. And will ther be any issue with my 410's

[vegasmarauder]

There really shouldn't be an issue with the 4.10's since they don't affect the problem with the hardness of the axles when they were made, but I wouldn't volunteer the gear info. I found the notice on Blueovalnews.com but I didn't have to show it to the dealer, once I mentioned it they said they were aware of it and would have to inspect it first. No problem with the repair at all. All the dealers are aware of it since it affects almost all the Panther platform cars. The axles got on back order because so many cars started failing at the same time. I think the back order problem is fixed now. 2003 and up is new axle shaft. Dealers don't always stock it.

I have a brand new 2004 (700 miles) and it makes a very cool sounding and distinct whine under hard accell. Of course, I haven't ACTUALLY pressed the accellerator that hard during the break in period. There is a faint whine (very faint) from the rear that I can hear on the highway, it goes away when I lift my foot. I think that the only reason I notice it is that the vehicle is so quiet otherwise. The accel whine does sound like the front pump, IMHO. It sounds like it is coming from the engine compartment or at least forward of the driver.

Let me be the first to correct your errant behaviour. Drive it like you just stole it. And the owner is right behind you. And he's armed and having a bad day. :uzi:

I think I speak for most owners here when I say, that is how we treated our rides, and they only come back wanting more 'abuse'. Change your fluids first at 5000km/2500 miles, but drive it hard.

If it's quiet, you're doing something wrong :)

I'm resurrecting an older thread because I have developed a constant whine that is audible at all speeds, and increases pitch with speed, and not just under pedal. I am not sure it is coming from the rear end, as though it is not very loud, it resonates through the cabin and I cannot tell where it is coming from.

We just took apart the rear end a couple months ago to check things since I was getting a vibration at 80+ mph, and we found nothing but normal wear on the ring+pinion. There are no leaks evident on my garage floor.

Reading Mac's post below it sounds like a bearing, but since we just checked that for the vibration I have my doubts. The whining did not start until a few days ago, and it was a few months ago (Dec.) that we took apart the rear end.

Any ideas?

Damn, I wish I lived near a mechanic that I could TRUST to give me truthful info. and knows what the heck they are doing. Seems everyone around here just wants money and doesn't have a clue. (dealers and service techs, that is) I paid almost twice what others have for the install, and paid for reassembly on top of that to prove to the tech it wasn't the gears causing the vibration problem I have (still).

I'll even drive to MN or Chicago if I have to, but this Iowa syndrome of people screwing up my car has to stop.

You don't have one of those fake turbo things you stick on your exhaust do you? ;) LOL j/k

[duhtroll]

Dang -

My secret's out.

No, unfortunately, I WISH it was that and then all I had to do would be leave the hood up at the McDonald's drive thru and some ricer would steal it - problem solved.

My God, there are just too many things wrong with these cars. Blue smoke, ticking engines, bad paint, blah, blah, blah. Sounds like my old Grand National.
