Default right rear axle popped out again!!!!!!

Ok, I am getting tired of this happening this is the third time for me! I have had both sides pop out on me - the right side twice.(both sides have the replacement clip) The funny thing is I rode the piss out of it on last weekend and then went for a light trail ride on Sunday doubling and the I could feel the back end handling funny so I stopped and the right axle is sticking out about 2 inches. I rolled the quad in neutral for about 4 feet and I was able to slide the axle back in - so I hope I havn't screwed up the splines.
Anyways I have been reading on here and some guys say they have put a "o" ring under the new clip before putting the axle back in - does any one know what size "o" ring? I was also wondering if anyone change the shocks and if this makes a difference ie. stiffing up the ride so the axles don't get into an angle so they pop out ??? I am thinking of going new as I am getting tired of pulling on the axle every time I stop after a ride.

Any help would be appreciated, Thanks!

I know that we've got guys in here who have either fought with this or have changed axles before so c'mon guys... Tellthe Fish what you did to lick this problem...

Hey Gunny! Didn't you have the whole rear end of yours apart this Spring???

Top of the morning Fish .... like Bob said, I had my rear end apart a fewweeks back, but the Grizzis still in pieces so I haven't had a chance to ride it to see if I'll have any problems like this.

When I tore mine down I re-used the stock"C" clip inthe axle & I had to "Pound" the axle in witha dead blow hammer (I didn't have to wail on it mind you, but Ihad to give it a couple of good raps)... I couldn't get it in by handnor by trying to shove it in.

You say you change the "C" clip ... with a factory stock one ?? And this is on the axle splined end, not the inner CV joint, correct ??

Riding doubleactually makes the Grizz squat more, which would level out the axles, so I'm not sure why they would pull out then ??

Another thing, with the way the A-arms are bolted up to the frame & the rear hub bolted to them .... how does the axle come out ?? I have my Grizz up on an ATV lift, with High Lifter Springs on the shocks set at the 5th position, & the A-arms & axles are just hanging in the wind & there is no way the axle .... on my Grizz .... can move enough to come out of the rear diff .... unless I'm missing something ?? .... which Imay be.

HopefullyHammer, Hillbrigger, Timmior GwrGrizz700 will see this & have some ideas, but I honestly can't see how the axle can move far enough to come out, especially when riding double.

You don't happen to have any photo's of this do you ?? You haven't "Flipped" your rear hubs over have you ??

Try this ...when the axle is in where it's suppose to be & with the Grizz resting on the tires, grab the axle & pushing in & pulling out, see if the axle moves .... then lift the back of the Grizz up so the tires & A-arms are just hanging &try it again. Let us know if there's any movement & maybe we can try & think thru this.

i haven't had this happen, but there are plenty of threads on here about it. there is a larger replacement c-clip, which you said you have installed. some guys have also mentioned that over filling the differential will cause pressure to build and pop the axle out. have you checked the fluid level? is the quad lifted? flipped hubs? anything else done to the suspension?

No problem Bob ... and I was just go'in thru my mind what might cause this problem. Like Hammer wrote, it's been discussed on here before & if I remember, most the time it happened when guys flipped their hubs.

But really, I have no I-D as to the "why" ?? ... Let alone the "how", after putt'in mine back in after the rebuild.

Thanks for the responses guys!

The new "clip" Iam talking about is the one Yamaha is recommending, and it is on the axle spline end. I have not flipped the hubs or done any modifications to the atv besides bigger tires on the stock rims which the dealer put on. I filled the fluid to the filler hole on the diff and was very carefully to make sure not to overfill.
My thinking with the double riding thing is just that the axles are more straight so they are easier to pop out! I don't know I am not a engineer I just drive truck for living!

When I was putting the axle back in the last time I had to tap it in with the hammer as well and once in and all back together there was no movement. Right now the right side has movement in it and the left side does not.

I have not got the axle out as of yet as I am waiting for my buddy to bring over his air gun so I can get the wheel hub nut off. But, when I drained the fluid out there was no metal flanks in it so Iam hopping I did not screw up the splines when the axle poped out.

Again, thanks for your help!

I'm even less of a mechanic than you are Fish... and that's pretty dang scary!

It seems to me that if one side is now different than it was before, and it's also different from the other axle, then something smells, well... FISHY!!

Iwas thinking about this & the instructions I gave ya about "Pull'in & pushing" on the axle. If you go to this thread,

www.grizzlyowners.com/index.cfm.... and scroll down to Section 5, click on the link thereand look at the photo's I have in photobucket .... the innner CVjoint is MADE to slide in & out.

So to check if you have a problem in the diff itself, you'll have to grab the Inncer CV joint Hub ... the Green thing .... and push & pull on it & see if THATmoves.

i believe that highlifter makes a replacement clip that is thicker than the yamaha one to help with this issue............but i'm not positive.
