The "Who broke it's axle" thread

[trueno86power]

If someone could take a picture under the car to check the angle of axle when at stock height would be great.

To the people who put on the DSS axles, how long have you been driving/tracking on them? And no clicking/creaking/etc issues whatsoever?

I just went out and checked mine. No pic.

It's almost perfectly horizontal but with a slight rise from the diff to the wheel.

Has anyone encountered this issue with the stock suspension?

And at stock power level.

@Ninjin I believe started clicking at near stock power. Just TRD intake and tune.

Hard to tell in my case, I went from "basically stock" to "full retard" in about two weeks. I don't recall ever hearing the clicking noise stock though.

Oh clicking was after the header & front pipe ? I thought you had it before. My bad! Regardless he is still NA. So i guess he is off the board for stock power.

Im having this same problem and I am gonna try to bring it to the dealer tomarrow morning. I think its been happening to me even before i got my mods. Right now I have coils and for a while I maxed them out so I was pretty low. Sound has gotten so much worse. My friend told me it was because I used my ebrake to drift but now I know that its an axle problem.

I will post this picture from an old thread here:


As far as I know, nearly all the breaks are in the same area and every one of them has been on a car that is lowered. Some have been tracked or autox but not all. But all have been lowered which apparently is adding additional stress to the CV joints. If you watch the above video you can get a better understanding of why that may be the case. That car is on RCE yellows with a drop of only 20-22mm (.80 inch approximately). Look at the angle of the axle during cornering and large bumps. Now think of what the angle would be with the car lowered 2-3 times that much.

This is a problem on many cars with independent rear suspension that are lowered not just the BRZ/FR-S.

A longer shaft in a lowered car would be a good start. It's tracking at the end of the race and you can see where it pulls itself down under power to cause the indents towards the outer range of that movement.
That wear suggests the car was lowered early on and either heavily tracked or had engine mods?
It's no wonder they are failing when the CV's are being pulled to their limits at an angle.

So am I getting this right? Any power mods and suspension mods (as in lowering) will cause premature axle wear/break?

That sounds reasonable generally except the problem here seems to be the shafts are a bit short.
Could the diff be raised by the amount the suspension has been lowered to keep the shafts straight?

I lean more towards suspension ride height and lower physical travel is the likely
Culprit. I'm not saying power isn't. But the lower you go the faster the axles seem to wear. I'll try and get some video this weekend of where mine is as I am near the lowest height on ksports. I am sure once we get enough fees back from users with a list of what they have done, driving style, and the event of breakage, as well as a vendor that sees the interest we an come up with a solution. Hell I know a local CNC shop that would love to start producing product for our platform if we get enough concrete info.
