LSD Failure LIST

[Jspeed17]

Anybody's tranny whine loudly? Or is it just the kartboy bushing making the noise travel up into the car? Had to change the clutch due to slippage with the added power, so i put BG synchro shift synthetic 75w-90 in it with an act clutch. Could it be the fluid i used, the bushing, or my LSD going???

I've been searching this broken diff subject for quite a while now and have not found the answer:

Does anyone know of a verified revised diff (no spring) being broken?

All the photos I've seen here and on other forums of broken MSP diffs have the spring (ie, pre-revision).

Any insight would be appreciated.

I have a 03.5 MSP with a production date of 01/03.

And this is my LSD it has no springs.

Awesome. I thought that post went un-noticed.

Thanks man.

Mine went in downtown Dallas. Just let the clutch out at a redlight, heard a small pop, and them vrrrrrmmmm the motor just free wheels no movment. I reved it up enough to get out of the road a bit and waited for the wrecker.
Mine went at 103,000 after 3 yrs+ of 12-15PSI daily.
Just random as hell how and when these LSD's decide to let go.

Nope not your fluid. Mine went at 103k miles all stock fluids.
The welds are just defective and I think all of them will break over time.

 

[TheMAN]

all stock fluids meaning you never changed them? :wtf:

No you dufus! Meaning the gear oil was stock gear oil and not some fancy pants, overpriced, syncro-whats-its-fluid. Some people felt that the after market fluids were a contributing factor to their diffs failing. The fluid has nothing to do with it. These diffs have failed under various conditions varying numbers of miles, under all kinds of driving conditions, and with both kinds of MazdaSpeeds with both versions of the LSD.
I personally feel that all of them will break over time. In fact some people have had two of these diffs break within a fairly short amount of time.

I will either buy a Quaife, buy someone else's rewelded stocker, or have my LSD rewelded.

I'd be happy it lasted 103K miles especially on the original version. Go Quaife if you want it to outlast the car.

 

[Pirana]

get an STi

 

[Fast lane]

Danm thing failed while i was cruising in second gear at 30mph..i then floored it the car took off then, just heard the car go to redline... oh well now its time for the quaife and the new gears.
15,000 miles 8,000 at over 300whp

Built Mazdaspeed Transmission

If any of you guys are interseted, I am selling a built trans. with a Quaife ATB LSD and cryo-treated gears, shafts, and syncros. I have a thread up on the FS index under jvjcivil Mazdaspeed preformance parts (pics and prices) page 2. I am located in central, nj and have a mechanic who would do the swap on a saturday. If you're wondering, I blew my motor and decided to go completely back to stock. I'm looking to upgrade to a luxury car.

Please feel free to send me a PM if you have any questions.

Looks like I might next on this list. Developed a leak on drivers side where the axle goes into the trans. Running on borrowed time, I think....

 

[JDM Sam]

Replace those axle seals quick unless you want to rebuild the entire gear box.

 

[Alejo_NIN]

do the o3.5, even tho are missing the spring, break easily too?

 

[Metal MP5]

24000miles, dealer replaced under warranty even though i have alot more hp than a stock msp

 

[carwurk]
