I was riding today and snaped the drive axle in half :help: What would cause this?

To much power? We where riding on some rough trails, but not any worse than in the past.

Boy does it suck when the drive shaft breaks , guess what, you dont go to far after that. Doesnt appear to have damged anything else

Back to the MEN'S CRISIS CENTER

Fatigue. Not a common problem, but I have seen it before, usually from hitting a hard bump just right. Don't stress about it, no way to prevent it.

Sorry to hear about the bad news :banghead: All of those years of "blindenley fast" acceleration, and "monster torque' has taken its toll. A drive axle, HOLY $@*!, the f-7 boys will be scramblin when they read this

I've broken 2 shafts, 1 on my 99 xc700 , 1 on a borrowed 98 Indy500.
On both shafts, the break did look rusty , like a casting fault in the metal. Only a minor spot (less than half) was shiny.

Edit: And be happy you saved the chaincase , more often than not , you'll have to replace that too when the shaft breaks.

Yes I have not looked super close at the chaincase yet, I am crossing my fingers.

I was slowing down for a bump coming out of the woods, felt a WIERD vibration coming from the track, stoped looked did see anything, hoped on tried to accelerate NO GOOD, I thought the chain broke, but nope.

I have never had a drive line failure on a POLDOG

Oh well

ivar, thanks I looked at it closer, got a spare chain case laying around :banghead:

I have broken my drive shaft on my 98 500 and have two friends that broke theres as well on different models.

seen more than a few during winter of '03-'04 on slightly older 700's and one 600



exactly same as i saw, polaris covered all of them, one broke again less than 2 weeks later too! , seems to have been a casting flaw was polarises answer
