Broke a Half Shaft today - BMW 3-Series (E90 E92) Forum

joec500 · 11-13-2012, 05:41 PM

Just got my car towed to FFTEC, as I blew up my drivers side (left) half shaft, I am hoping there is a not any collateral damage.

I would assume if only one half shaft broke, the car would still move to one side?

I have a wavetrac LSD in the car, and was doing a 1st to 2nd gear rolling start, not even a launch.

That Vishnu Flexfuel kit is no joke.

I will hopefully have more updates and pictures for you guys shortly. Just another data point that even guys with LSD's and DO NOT drag snap these half shafts.

sorry to hear. keep us informed. I think this happened to BuraQ recently, right?

Dmacc · 11-13-2012, 06:11 PM

I guess lucky for me I don't have a second gear! I spin the tires too badly

but I'm sorry to hear about the way it happened, that is just mad torque

Thanks, I think we met at FFTEC last week, I see your car is running great!

The PSS's have great grip for street, what tires are your running?

enrita · 11-13-2012, 06:20 PM

sucks! what mix are you running? any logs ?

CHECKERED · 11-13-2012, 06:24 PM

Pics or it didn’t happen

Eric335 · 11-13-2012, 06:25 PM

Ouch! Upgrade both half-shafts?

Unfortunately I'm running only 245's on the rear and on the front I'm running some harder winter tires for the rain, but spring time i'll switch over to some PSS's

Yikes, sorry to hear that man. Hopefully you can get it fixed before your trip. Good luck.

100% E85, no logs yet, as I just solved my misfires on Sunday

cn555ic · 11-13-2012, 06:51 PM

What was the cause of misfires and what did u fix to make it go away

I couldn't get a pic underneath the car while it was sitting in traffic, but there was grease all over the inside of the wheel barrel and NO MOVEMENT when the car was in gear, just the sound of broken rotating half shaft

IT was some combinate of new injectors, replaced 2 Pre-cat o2's and removed a clogged cat (burned up cat clogging the flow and creating more heat in Bank2)

I can't point to the exact issue, but I think it was most likely replacing Bank 2 injectors for my bank2 misfires.

I honestly think the stock Drive Shafts are ok for Street assuming you resolve any wheel hop issues. I think Toe Arms are in my near future. In order to get DSS, I need working DriveShafts to be sent in, so I will be going with stock replacements and looking into Toe Arms to assist in the Toe Hop Issue.

It's the wheel hop shock jolting our DriveShafts into submission, because I remember spinning out 1st gear than droping right into 2nd gear, and I think I regained traction abruptly thus tearing apart my half shaft.

Okay, thanks for the explanation. Are there many options besides OEM ones anyways?

Also, car looks good as always, if it makes you feel any better

There are upgrades, but I need my car back soon, as I am going overseas and need to be able to drive the car home, so it doesn't sit at FFTEC's garage

I will eventually send my driveshafts to DSS for upgrading.

Thanks for the clarification! When you say overseas, are you being deployed? Or just for work?

Either way, goodluck!

So just to clarify, you were accelerating through wheel hop after shifting into 2nd when the axle broke, or did you just shift from 1st to 2nd quickly, and then dump the clutch which resulted in no wheel hop, but a broken axle?

Also, I don't think DSS needs working axles. They replace the bar and the CVs.

The Driveshaft Shop upgraded axles require you to send your half to them for the upgrade. They can be snapped in half and it doesn’t matter. They will tear your old half shafts down and upgrade the race and cage that comprise the inner CV, then upgrade the bar to much stronger parts.

Everything happend so quickly, but I do remember the snap occurred the moment I dumped the clutch from 1st to 2nd. I know the rear end was not as planted as I would like. Working with FFTEC to resolve the root cause rather than just getting stronger half shafts.

Also the big thing about going with DSS's is I need the car ASAP and don't have the flexibility to wait for DSS to rebuild my halfshafts.

ajm8127 · 11-14-2012, 11:18 AM

I see. I would say there wouldn't have been much wheel hop if it broke immediately.

What makes you think the half shafts themselves are not the root cause? With 100% e85, you should be making around 450 ft lbs. of rwtq, right? That like a 60% increase from stock.

Damn you got towed but please next time use a flat bed bro. I cringe when I see those front tow hitched tow trucks being used.
