lsd warning?

[MrDiggler]

i had none..just happened

Welcome to the club Discreet. Sorry to hear about it.

Yep, it's called branding. It sells cars.

I thought that Mazdaspeed was a racing division of Mazda. I think it goes something like this. Mazdaspeed is Mazda's in-house race and street car tuning arm and is highly involved in both amateur and professional motorsports.


Hmmmm, I think I saw racing in threre. (scratch)

Well, I know that, of course, but that doesn't mean the car is built for racing, which it clearly is not. I guarantee you don't see stock MSPs on the racing circuit.

didnt a msp finsh 1st or 2nd in SCCA nationals last year?

and nope theres no warning that your lsd is going to pop, and its not only when racing that it will pop either. I was taking my g/f home and pulled in her apartment complex, hit the gas to carry me around the corner (1400-1500 rpms) and *POP*

these threads ******* scare me

That's why I ordered a quaife while replacing the clutch.

and this is why I pulled my LSD out,and re-welded it,and replaced the clutch with a stage 3 hybrib SPEC.

BEFORE it became a issue.

 

[goku4658]

did you go to a shop to get it welded?

i was under the impression that the lsd cracks from the inside out meaning that rewelding it before it broke would only serve as a band-aid?

I pulled the diff,and had a friend weld it.

no,the reason they breake is because the stock wels are not enough,there are 4 small welds,and they are not sufficient to hold.


look at some of the pics here on the forum,they broke at the bad stock welds.

after looking,and spending a long while thinking about how else it could be fixed,I ended up TIG welding mine just like turfburns

Me too. Noticed it after I installed the AWR Front Motor Mount. Sounds like two pipes hitting each other. I pulled out all my FMIC pipes, wrapped any areas that looked like they were hitting something and reinstalled. No difference. I'm going to mark my front motor mount, drive around and see if it is loose (if markings don't line up).

If it's not a loose front one I think it is a torn rear one. My clutch still grabs strong, doesn't slip. There doesn't seem to be any corrolation to the sound and turning/power, it only happens when I engage first gear, or sometimes in second if I let the rpms drop close to 1000. I've checked everything else I can think of.

I'm going to take JDM Sam and LinuxRacr for a ride tonight to get their opinions. If we get this figured out I'll post back up.

you guys figure anything out?

no worning,when it snaps it snaps.

agreed.

 

[carbonkid]

QUOTE=MrDiggler]No. There was no warning on mine before it went, and it went when I least expected it to. Putting along in 1st gear at under 3k rpm's. (WTF?) All of a sudden you'll hear a pop-crunch-grind thing and the car won't move under power anymore.[/QUOTE]

exactly what happened to me!

do you like your SPEC s3? I ordered the s2 (debated on the s2+ but didnt see my car ever seeing that kind of power). Is is fairly streetable?

Nothing defenitive. General consencous is the rear motor mount. Haven't pulled it out yet to check for sure. I'm going to go in and try to warrenty it later this month when I get the front bushings replaced.

3 hybrid is a great clutch,feels just like stock,exept you have to be more accurate with the gas,and release as it is easer to stall.

Only thing I can think of re: the banging of pipes sound is that the tranny mount for the exhaust on aftermarket exhausts wasn't replaced - pic of where it should be. with stock motor mounts or softer aftermarket mounts there will be a lot of movement at this spot and it might more around that much.

Plus, if it's not attached here all the flex is being absorbed by the exhaust manifold / turbo manifold which could be a reason for cracked manifolds... Check this anyhow, and if you don't have a bracket/support there, go get one put in.
