Broken drive shaft
 

Fortunately it failed on the dyno and not on the road. One year old DDS aluminum drive shaft. No warning NVM. Tech said the bolts had worked loose. Hard way to learn a lesson: Check and retorque bolts.

Did you reuse nuts and bolts?

Use blue locktite

Damn, what does the underside of the car look like? Any major damage?

looks like to me its a bad driveshaft no way loose bolts cause that but where is the carrier bearing at?

I'll go with the "bad driveshaft" theory.

Is that blood all over the floor? - :eyebulge:

Yikes! I have a stock driveshaft if for free. You just gotta pay for shipping from California. :)

Oooof. The red stuff on the floor makes it look like the driveshaft died a horrible bloody death.


How's the underside of the car look?

First of all, I'm not answering any questions about possible blood on the floor.


There was no damage to the underside of the car. The tuner shut it down as soon as he heard/felt it go.


PTuning already sourced a replacement shaft. Thanks for the offer



It's a one piece DDS aluminum shaft.


Yes, I reused the bolts.


And yes to the Loctite.


I'll add checking driveshaft to my pre-track check list.

...pending litigation and all that ;)

i'm sure tommy had it coming.

I bet when it went the drivers seat got totaled!

Subaru notes these as one time use items but I never understood why, if its not rusty/striped what's the mechanical reason they can't be reused?

Looks like a two piece shaft to me!?

Maybe the bolts are TTY?
