hey, I was wondering if many people bend there axles on there 400ex's. I am wondering if mine is bent but I can't tell. I think this because when all four wheels are on the ground it drives pretty straight but when I am wheely-ing I dart off to the left. I am pretty sure the tire pressures are the same. If it is bent, what kind of axle should I run and how long should it be for mx. I was thinking a lonestar +4 thanks

 

please help

 

you should put it up on a jack ander the motor lift up the back tire start in put it in 3rd let out the clutch and go behind it and look at the tires if one is woppling there you go bent axle . IF your axle is bent then defiatly go with the +4 lonestar i plan on getting one for my 250X

 

Good idea KKKiller (love that name!!) When I had a bent axle on my Recon I KNEW it. I had to drive home feeling like I was on whoopes while I was on a smooth dirt road!! However, with my new 400exwhen ever I need a new one I'm going to get a andjustable one. For some reason I don't feel comfortable on a +4 axle with stock A arms. I feel like I'm riding a three wheeler. If you have +2 a arms then go with a +4 if not I would sitck with a +2. I'm gettin the adjustable so I can keep it at 2 then move up to 4 with +2 a arms. This is just my opinion though. I have a philospy about opinions some people might remeber it[img]i/expressions/face-icon-small-smile.gif[/img]

 

I would think the least amount of irregularity in the axle would show up with a simple jig-type setup pointed directly at the center or axis of the axle. Just about anything should work so long as it and the axle remain stationary on the same axis with the rear of the ATV elevated so that the wheel can be rotated by hand. Then just look for the least amount of wobble as the axle is rotated near the stationary pointer.

 

Ya atv69rider you should listen to redreconrider about the adjustable axle and a-arms i m going yo dot the same thing to my 250X

 

And Dont forget, if only one wheel is wobbling, then it might be the rim, which is alot easier and less expensive a fix. I have(pretty sure at least) a bent rim on my blaster right now, not too bad, but I can tell its the rim because it doesnt bounce the hole back end. Thats how I heard u can tell.
