Default New Axle Shaft Breakage/Damage TSB

SOA recently issued a new TSB and its description is at http://techinfo.subaru.com/html/disp...p?doc_id=73234. I hadn't realized that people were breaking their axle shafts often enough to warrant a TSB about the problem.

I think that has to do with the STI more than anything else. If the DCCD stays open or you are in manual mode and set it that way 2/3 of the torque goes to the rear wheels. If guys launch by just dumping the clutch at 6000rpm, you can get axle hop in the rear which snaps axles, usually at the outer CV. I've read 5-6 cases of this on the board here alone. It's a lot better than breaking the rear diff or transmission. The new axles are expensive, although it only takes about 10 minutes to swap them, I've heard of them getting covered under warranty. I can't see how under any normal driving you'd break them.

I've snapped 2 axles... it's annoying.

Exclamation Broken Rear Axles

I experienced the disappointment of breaking my rear axles first hand last week. My factory STI has been in the shop since. I have gone back and forth with the dealer. I was not launching at 6000 RPM as the TSB describes the root of the problem. I hit 2nd gear at like 4500 RPM and that was enough I guess. So donít drive like Solberg because the rear end in the STI are not designed to handle the 300ft-lb of torque the engine and transmission are touted deliver. They did agree to pay for 1/2 of the more than $1200 service fee.
