Yes. In my opinion, the solid carrier brgs. that have been suggested, & rubberbands that CanAm suggested putting on the drive shafts, is like putting a Band-Aid on a compound fracture!! It might stop the bleeding, but doesn't address the problem This is only treating a symptom, not addressing the cause of the vibration. It's not the noise that is the problem, it's the destruction that the vibration is doing to the bearings & gears. The noise just tells us there is a problem.I will do once I get my machine back from the dealer. 100% agree, the drive line goes into a resonant condition. In other words once the natural frequency of the driveline is met, ie.4600RPM, it goes into a resonance condition. Gnerally to fix these kind of problems, you either have to fix the source, cut the transmission path or mask the speaker where the noise is radiating from.
My brand new 2021 Commander Max Xt has this exact issue right out of the gate, it rattles like hell around 4600RPM. It also sweats front differential oil as well after the first drive!!! Very disappointing after spending 24K. I have it at the dealer for the diff leak now and mentioned the set screw solution for the rattle. Not sure if they are going to follow thru with the set screw or not? Is there an after market carrier bearing that you can purchase for the 2021 Commander Max XT?
I also bought brand new 2021 can am 1000R max xt. Makes same vibration…right off the trailer from the dealer. At first I thought it was the after market roof the installed. After investigating could trace it to down below. my problem is this….. if it’s in park it rattles still at same rpm, as when I’m driving. Shaft should not be moving in park. But get the vibration approx 2800 rpm ( give or take) so to me to waste time in the carrier bearing or the set screw would not take care of the problem ( as other people have mentioned) I have zero faith in these dealerships as they didn’t know as much as I did when sellling me the machine.F ing ridiculous $27k and can’t even ride it!!! I bought this machine for can am reliability….. I believe there is a flaw in the way they ran something so that at certain engine rpm it rattles/vibrates. I will be pulling the belly skid plate and seeing if I can narrow it down and will report what I find. Otherwise when I head back to dealer will be to drop this machine off for my money back!
