Hey everyone, new to the site, and glad to be here.
Just purchased my first atv, a 2004 Grizz, which is running great, however Im
wondering about clicking sounds when braking on steep downhill descents, or sometimes when I decelerate, or hit bumps at speed. A buddy with a Polaris 700 drove it, and said it sounds fine. Can anyone else relate to this, hopefully its just new machine paranoia. Thx

Welcome James!
The sounds you here may or may not be normal, but, mine does the same thing. I'm actually glad to here that someone else's machine does this too. That makes me worry less. If I'm correct the sound you here comes from the rear and happens mostly while your rear brakes are engaged and decending a bumpy hill. Sound right? I'm not sure what it is but, I'm not too concerned about it. I don't think you would have to worry about it. Later, Clint.

Thanks for the input, Clint. It is reassuring to know that you are hearing this as well. When it goes in for its first service I will mention it to my dealer and see what he says. Ideally, it would be nice to jump on another Grizzly to see if it sounded the same, anyway if I get any info I will pass it along.
Thanks again, James

Well just to put your mind at ease both my 04 Grizzlys do it also. From what I understand the rear driveline chatter you hear at breaking is because the rear brake is located inline with the drive shaft instead of on the rear hub as normal. Thus being the disk brake on the drive line when brakeing you get the so called drive line chatter. Hope that helps.

Extremegrizz, your definition about drive line chatter makes alot of sense, I guess if both you guys are hearing this as well, its problably normal. Must be that new machine syndrome, not suprising considering my friends give me a hard time about cleaning it while on breaks out on the trail. That is another issue however, as it seems to me that the stock cv guards hold a lot of mud and leaves up against the boots. Same thing with the main skidplate, as I really have to take it off to get everything cleaned out, Im curious as to wether an aluminum plate would be easier to clean out being less of a tray shape, not to mention the additional protection.

LOL James on the cleaning. I know where you are coming from on that. Had some sort of atv,atc, scooter or anything with wheels and a motor most of my life but I still and make sure both me and my wife's machines get cleaned after ever ride.

Not just because new, had two Honda Ranchers prior to the Grizzlys and had their fair share of battle wounds from the woods or even a roll over of my wifes that was my fault while ridding it (oops).

As to your comment on the alum. skid plate. Alot better protection in ways of rocks and such but it still holds alot of dirt and mud. I have Aluminum Products under belly skids and rear bash plate on both and factory Yamaha alum. skids on the a-arms, front bash plate (as they call it). The only benefit for cleaning is that it is a little easier to wash the dirt out but it still gets hung up on the frame rails and will not wash out.

We bought (2) 2004 Grizzly's, one for my wife and one for myself and right now they are at the Yamaha dealer getting new CV joints in both of them. They are only 2 months old. We love them a lot but they were both making clicking noises. The one was real bad, it even made it when you were going foward turning to the right. Both were clicking when you would back up. I have also heard of 2 others having the same problem. So listen to them and I hope your dont have the same problem. By the way ours made the same chatter noises, i'm hoping that it was not the beggining of the CV joints going bad. Good luck and have fun.

Thanks for the input QuadCrazy, not the kind of news you like to get but at least your dealer is looking after you. Just curious as to wether your dealer mentioned if they have seen a lot of these cases, or if he said anything about driveline noises, etc. Maybe if you get a chance you could let us know if your wifes and your grizzly needed the same cv joint replaced or different ones, ie:
inner, outer, left, right, front or rear, etc. Its odd that machines this new would need these already. It kind of makes you wonder if there was a bad batch or something at Yamaha. As I mentioned earlier, my machine is going in for its first service soon, this saturday actually. and I intend to speak to my dealer about it and see what he says. Its nice to have other owners share their input as I will be a little better informed when I bring it up. I will let you guys know how it goes. Hopefully you get your machines back soon!
Regards, James

Hey James!

Like they all have said,it is the drive line braking system enegaging when you are applying the brakes with the foot pbrake or the hand brake.But the sound should be coming from under you or behind you when you are in two wheel drive mode.Now if you are in the 4 wheel drive mode it could from the front also when you apply brakes when going down hill.

Ever got under you vehicle that has rear wheel drive? Like for instance greasing the u-joint`s if it has them and grabbed the drive line and tryed to twist it in one direction or the other while it is in neautral.There will be some play in the pinion of the differential,that is what you will be hearing when you apply the brakes. It`s the ring gear catching up with the pinion gear in a deceleration of putting on the brakes.

Swampy Joe, basically the dealer said the same thing, not as well as your explanation however. Much appreciated, not going to worry about it anymore.

Ive found that if you are going through steep trails , if you switch to 4-wheel low that the chattering that you hear stops. I do this on all steep terrain now just so I won't here the chatter.

Sorry but chatter is not the clutches but the rear caliper chattering on the disc. All grizzlies do it. If your clutch is chattering then it shoild be regreased.
