thought this was only effecting the 09 models but alas, i believe it is a design issue with the long upper a arm bolts. i am an over tightener by any stretch of the imagination so, i cant believe this happend to me.

make sure you all check your upper arms on stock and aftermarket front upper a arms a few times a year.

the wife and i switched sleds because hers broke the scratchers and she couldnt keep the sled cool in the spring riding conditions we were encountering. i could drag my feet and keep the sled cool. as she crossed a road on my sled to go to the home we were renting, the sled made an abrupt right turn, and flipped over sending her over the bars, rolling the sled on to it's side. the bars stabbed her thigh, and her knee's took some abuse from the ground impact (didnt have her kneeguards on as we were on a cruise ride just going out fishing).

thankfully she had her tekvest on and she didnt get hurt any worse than she did, and the sled didnt get any rash at all. the sleds right upper a arm bolt backed out and caused the failure. i tore the front plastics off the next am and found the issue, reinstalled the bolt with locktite (again) and for giggles checked the left side. IT WAS LOOSE TOO.

i cant imagine what would have happened to either of us at a higher rate of speed. she was only going 2-3 mph crossing a road/driveway from a stop. i was testing clutching, and the new drivers i installed just minutes before we switched sleds. someone was looking out for both of us.

just giving a heads up to check your bolts guys. ski
 
incredible you mentioned this....I had the same thing happen today, returned from two days pounding hard in the hills...and pulled the sled out of the trailer...and then the bolt gave way...bent the suspenion forward, and since I was going slow it just stopped me...cant imagine this happening at speed...

got to locktite them I guess???

and oh yeah....EPIC day!!!!!!
 
thanks for not rubbing it in MT. LOL!! we have had a few great weekends as well. the snow is winding down in the north but we made lemonaid when mother nature gave us lemons, we just started ice fishing, and antler hunting. LOL! the walleye bite has been awesome. and lynne found a HUGE moose shed. ski

after a review of the fasteners and thinking (yeah i know) what we can do to fix this... i may have a really cheap and easy fix. LOCK WASHER on the back of the bolt head. it will cost about a dime to fix both sides. remove the front bumper and nose cone, remove the long bolt, clean the threads on the bolt and the nut insert in frame, add loctite, and the lock washer. re-torque. things you come up with when you are in the shower. (sorry for the visual). ski
