i havent ridden in over a month and im goin nuts, last time i road was out in the ditches by my house. i was crossin a hwy to go to a beanfield. i dropped off the hwy on my scrambler and landed in the beanfield, i heard a loud noise but i thought nothing of it because i figured it was the chain, i slowed down and shut it off just to let her cool down. after the air cooling shut off i started her back up and went wide open and pulled up to do a wheelie and all i heard was the worst sound of metal and metal griding together. i look back and figured it was something with the chain but i didnt notice anything, i drove it back in 4 wheel drive and didnt ride it for about a week. a friend of mine came out and he wanted to see my flat track i made in this bean field. i told him what had been goin on and we pulled it out and i punched it and he watched the drive, we figured out it was something intertal with the rear drive system, the engine was runnin great and the front drive works. i dont have very much knowledge about mechanical problems with four-wheelers and i cant take it into the dealer cuz my dad doesnt have the money to fix it right now. if u have any ideas at all what the problem could be please help!!!

 

Is the chain loose and skipping on the sprocket? Also, take a close look at the sprockets and see if you have any missing or broken teeth

 

Nope the chains not loose and yeah i check the front and rear sprocket and theres no teeth missing at all so it has to be internal

 

Check your gearcase fluid.........see how many metal chips are on the end of the dipstick.......It could possibly be your chain is not lubed, and is binding....you you have a broken sproket(?) in there.......

 

Check the trany case on both sides.This is what it sounded like when my son broke the case on his Trailblazer.It was broke into onthe belt side.

 

I experienced that situation last week, but for me it was my front sprocket. We took it off and wow, no teeth on it at all, rounded out completely. It's hanging on my wall.[img]i/expressions/face-icon-small-smile.gif[/img]

 

what did he do to get it broke on that side? rock hit it? i wrapped my chain around the sprocket a while back over the summer and raipped a huge chunk out, started on the right side and went to the left side. 600 bucks to fix. ouch

 

He was jumping too high with a loose chain and landing on throttle.Fixed it for $250.Got a tranny off ebay and had to redo it.Looking for a left hand case for a 2000 -up Trailblazer or any other 2wd chain drives would take one with a small crack that could be welded.

 

Hey!! thanx for all your suggestions and when i have the time ill get out the manual and check some of your suggestions out, ill keep ya posted if you were right, thanx again

 

it sounds like it could be the bolts where the swing arm mount they will work them selfs loose it will let the swing arm slide to one side under acceleration and the chain will jump.. sit the quad with the rear wheels off the ground and see if there is any left right movement...
