Read clear through this thread this morning. One thing that is not clear at all, is what exactly is 'clicking'? . CV joint? Axle spline?... Locked Diff?

Seems to me that if angle is causing some of this, you apply some weight to the rear.. make it squat a bit... even the CV angles out... and if it was the angle, that click should go away... but the fact that this is happening more in turns on hard pavement... just screams diff at me. Anybody have a parts breakdown of the rear diff on these? I'm going to go through my service manual and check as well...
Just seems that if there was a hard click... you would be able to see some metal to metal contact somewhere... ?

Gonna be late for work now.. had to pull the service manual out.. .okay.. not the diff... unless there is some interaction with ring gear clearances and axle length...

It’s the CV joint.
The quickest way to get a CV joint to click when uncertain is to put the machine in a tight turn.

I’ve got a spare Oem that I can measure compressed and expanded. Would that help?

Is it just me or do the splines look a little different. Could be the pic???

The guys that had it, OEM and ours, had it in a slow turn...right from a stop. I was afraid it was the diff, and maybe some kind of weird side load thing because the rear is locked.

It's the traction loading and unloading while on a medium to high grip surface. When tension builds up during a turn, and then one wheel looses grip there is a backlash in the drive parts and that makes the noise. The part tolerances on these machines are large. You might be able to make the noise lessen with brand new parts, but it will soon return with a little run-in. I have actually watched my machine spit out a little grave the same time the noise happens in a very slow turn. Go out on ice/snow or mud and make the same turn,,,, no noise. The only way to eliminate the noise would be to custom build parts with MUCH smaller tolerances.

I have heard what Bumblebee is explaining many times in a hard corner with the locked spool.
It is a one time pop and not the continuous click of a CV joint.

What Wolvyman had couldn’t even be described as the common clicker, it was something awful that no ones ears could tolerate and there is no way it would have lasted 1000s of miles before destruction. It was just plain a bad axle from the start.

As of this weekend I now have a popper with about 1,400 miles on the RMAX4 . Rear driver, I think. First noticed it when moving on dry asphalt to load it onto the trailer. I always take precautions and make wide turns on pavement to minimize drive train lash and binding to the CVs. But alas, I am now afflicted. One thing I noticed when checking on it during the ride is that the inner axle housings get very hot. The outers I could grab, the inners would burn me if I grabbed one. The final drive was hot, but not scalding like the inner CV housings. So, a lot of friction in the inner CV joints. I assume they have proper grease, but may squirt some moly in to see if it helps with the heat/friction.

It's been asked, but I haven't seen an answer about whether these popping axles fail or just continue to make noise in beat to wheel rotation. Pops during a turn, though I didn't note if it's both R & L turns. It even pops driving straight ahead for a couple rotations then quiets down. More study to follow. New axle in stock and ordered from RMATV as a backup.

Usually they will make noise for a while before a complete failure.

Mine is making the clanking noise and I have ordered new rear axles, not sure when they will be delivered. When I put weight in the rear, noise goes away for sure. replaced the fronts with Rhino 2.0 and going factory on the rears.

I was hoping there would be some update here

He will update you, give him some time.

I meant with everyone else's reported axle issues, stop sales, etc. Just curious whats coming of this.

 

[SuperATV]

Nope. No issues here. Like in my response to your PM, I may have the guys keep them off the website for awhile till all this forum drama subsides and the community realizes the issue is with the suspension and not with the axles, OEM or ours. But currently, no issues on ours.
