Lsd Failure Thread

[03Speed]

Wow! Wanna sell me your tranny?

I wasnt able to part the car out; the insurance company bought the title and they are going to fix it and resell it.

Well here is a pic of my diff. You can see the seam where the ring gear is a little off from the diff body. I'm going to have that gap between each of the "studs" welded so that the gear is fixed to that part of the body. that should prevent it from ever shearing the body off at all.

ddogg777-

The lsd is in 2 pics where the gear and the spool is shown
Its supposed to be attached to the center piece of the drive gear.

hmm im hearing all these problem with the speed and its getting me parinoid. I just hit 10,300 miles without taking it to the dealer. Actually now that I think about it...once for a blown tire and reflash. Im gonna go in for alignment...I will sure to ask about this problem.

well Ive always been told that the only lsds are quiafe LSDs. Doesnt suprise me that our LSD sucks but I didnt think it was that bad. I tought Tochigi Fuji Sangyo is a pretty ligit Japanese company that makes driveline components.

I am very concerned about this...and if they bill me over $2,000 im gonna buy a Quaife LSD and do it myself. Im hoping that my dealer doesnt give me crap when I bring it in.

I pamper my car and I guess thats why its been so good to me lately. Sorry to haer about all the pain in the ass problems...keep us informed.

Covered under warranty for now...rep came to inspect it.
Waiting on LSD to come one. Delivery is To Be Determined...
Meaning no body knows, just like my headunit.

Holes from what??QUOTE]
Differential pins blowing through the transmission.... nasty stuff. After adding too much nitrous, a ventilated tranny is the second mod on open differentials.

Damn, seeing this picture of the complete one, and then seeing the picture of the sheared one puts it into perspective. I may follow your lead on this one.

I especially have concerns with the amount of racing I do and pushing over 200 whp... And all that on R-compound tires and speeds up to 100 mph or better... so yeah I want that bastard to stay in one piece... not two! If it breaks even with the welds then next up will be quaife... but for now I'd rather spend 500 bucks on a diff then 1200... if my 500 holds up.. sweet In all honesty I can buy and install 2 MSP LSD's for the price of a quaife...

 

[spacemonkey]

How many of these blown diffrenetial are 2003 and how many are 2003.5...just curious.

 

[Captain KRM P5]

I could have sworn that the LSD was made by tochigi fuji sangyo? Doesn't sound very much like Ford to me....

the LSD is not by Ford. the bearings are Ford.

33% is enough to have some say in their interest. Go see how many idiots flood their Renesis engines. Leaks in Mazda 6s as well, just do a search on their issues. I'm not crying about Callaway's part in the turbo. I'm in this thread talking about how CHEAP the LSD is as stated on page 1 with the quote out of SAE.com. I for one would be happy if Mazda bought my damn MSP back. I didn't pay 20k for a car to keep having problems pop up down the road and have no warranty to cover it b/c they want to say the way you drive abuses the car and that's the reason why it broke. They sold the car saying its meant to be driven.

THE POINT BEING-
We bought it not to drive like a granny so we will enjoy our cars. I don't drive it everyday like I am in the Indy 500, so they need to quit pulling that excuse to why the parts are failing.

Now back to the original intent of the thread.
WHO HAS HAD THEIR LSD GO OUT ON THEIR MSP?

SAE.net said it made the differential more affordable. You applied the label as "cheap." You are the one saying it is cheap, not SAE.net...

The part is not a piuece of crap.

From what it sounds like, rough starts and "drag racing" style starts are breaking these things. Once again, go read the article in GRM and see what the differential in the MSP was designed for. IT WASN'T DRAG RACING!

 

[JDM Sam]

"You pay for what you get" mean anything to you? A Kia Rio is affordable and it's a pos.
Who said we were drag racing and rough starting our cars? I was driving into a parking lot and it failed. Yup, I always do smokey burnouts when I drive around town.

I dont drag, i do road course, i.e involves turns.

Then why did you buy a Protege?? According to your theory, the H2 would awesome and would never break because of its price tag.

Same would follow for Porsche, Lambo etc...

Affordable does not mean cheap. To you it might, but once again, I refer you to my previous question.

How often did you drag your MSP? Don't be foolish and assume that the breakage occurred because of your pulling into a parking lot. How often did you have wheel hop? How often did grind gears?

To say that your differential died from pulling into a parking lot is dumb. Things don't break instantly and you know that.(headshake

PS - Have you read the article yet?

WOW!! Never knew that was what a road course was...(jerkit)

 

[TurfBurn]

Guys lets play nice. Seriously the bashing back and forth isn't getting anybody anywhere.

The fact is that several of these differentials have broken so there is some weakness that can be brought out in them one way or another. It could also easily be bad quality control and a number of the differentials went out with bad welds. You'd have to pay a lot of money to have that checked and to do a study... so there is no real way of knowing in the end.

The only fact that exists and really matters in this whole deal is that the MSP LSD CAN and HAS been broken at the weld mating, and thus that is the weak point in the LSD and has been exceeded one way or another by more than one person.

First, I rarely had wheel hop because I learned how to launch and not drop the clutch. Second, If I paid 20k for the quality build of a KIA I would have bought a KIA. My tranny grinded maybe 3 times before I switched over to synthetic fluid. It's also been documented many people have had problems with the transmission shifting into gear. I know how to drive a stick unlike what you are thinking. (jerkit)

My Msp is my daily driver. I rarely race it, nor did many other people buy it for a drag car like you are assuming. I bought it for an all around performance vehicle. Anybody can look inside the LSD and know it's not strong enough to be used for DRAG use. Don't assume everyone who buys a MSP drags the s*** out of their car. Don't get me wrong I open up my car, but if you're gonna tell me it can't hold up to me flooring it, then its weak and bad quality. Mazda sold this as a performance vehicle, if its not performing what good is that?
Keep in mind not every MSP is on this board there are other failures that aren't listed. This was a known problem when the car was released. Sport compact car even stated that it's a weak point in this car.

BTW Why dont you link me to that article since I dont read that magazine.

PS do you work for Mazda b/c you have the mentality of a stealership.

Don't assume you know what I am thinking. I never said you don't know how to drive a stick. If you assumed that, that's on you.

And thanks for clarifying how you drive your car. That will help people understand if it failed becuase of abuse or because of an actual mechanical defect.

There is no link to the article becuase it is only in print. Why don't you go out and hang at the freakin' book store and read it. You might learn something from a real magazine that has real tech, unlike SCC or orther Primedia rags...

And, no I don't work for Mazda. However, I'm tired of whiny MSP owners crying everytime something breaks...There is no consistency between people. They either claim they know how to drive, when they can't, and it is actually their poor driving skills that breaks things, not actual mechanical failure.

The transmission failure in the MP3 and MSP comes to mind...

 

[JDM Sam]

Believe or not, I am working on getting a hold of TSF to see what they say about the failure...

A TSF will just tell you the LSD failed not how specifically. BTW How do you have access to each individual case?

And thanks for clarifying how you drive your car. That will help people understand if it failed becuase of abuse or because of an actual mechanical defect.

What does this mean? Still insisting it's driver error that caused failure?
Well then there are 7 people that have had their LSDs replaced, so all 7 of us can't drive then... (jerkit)

Grassroots Motorsports? Real, big time racing info there. I have better things to do than go to a book store and look for a magazine about auto X when I don't even auto X.

What's so inconsistent about 7 LSDs failing? That is what this thread was for till you and another asshole accused everyone with a broken LSD of driving like morons.
Oh why don't you just stay out of the MSP threads when you DONT HAVE a MSP? You wont have to hear us whine or b**** or cry about our problems!
