I have an '06 renegade 600 sdi with 940 miles on it which I just purchased in march. Got some snow yesterday and was able to get out for a ride. It makes a rattling noise while driving which is more noticeable at slow speeds and when turning. I've determined it's brake related because when I gently apply the brakes as I'm driving the noise stops. I've read up on the forum and see the issue with the rotor key. I compared the amount of movement of my rotor with the amount of movement in my father in laws '06 550 fan and it seems to be identical. His sled doesn't make any rattling noise while driving. Is it worth taking the chain case off to replace the key or can I just drive it and ignore the rattle? I've read a lot of posts where the key is replaced and a few miles later the slop has returned. Is there anything else in the brake system I should check to address the rattle? The pads have plenty of life left and seem to be seated in the caliper just fine. Thanks for any help or advice.

Here are 3 videos I took today. If you listen closely you can hear the rattle.

I tried listening to your videos but had to ask permission to view the file.
Is your chain case tension set properly?

I gave you permission you should be able to view them now. I think the chain tension is good. When I ride the brake gently the rattle stops which is what led me to believe it would be the brakes. Would the chain stop rattling if I rode the brakes as well?

It could, I'd say its definitely worth checking and setting, as its fairly easy to do. A loose chain could be bouncing around or slapping the case, applying the brake would put tension on it i would think.? Best to try the easy thing first and go from there.
From what I've read you tighten the adjuster as much as you can by hand and then back off till the locking pin can be inserted into the adjuster hole.

Definitely coming from the passenger side chain case/brake area

Have you tried to replicate the noise with the track on a track stand? May not work though with no weight/tension/resistance on the track. But worth a try, then you could use a mechanic stethoscope to pin point the noise. Def a loud rattling.
Or remove the side panel and ride it? Try to pin point with a mechanics stethoscope that way too.
I put it on a stand and spun the track. No noise to be heard. Must be because there's no tension on track.

May want to check inside the chain case anyways, new bottle of chaincase lube is 12 bucks and could probably be changed anyways.
It would be good to check everything in there (bearings, bolts and nuts are tightened) . And then you can check the brake rotor and key.
Only special tool you'd need is a large socket for top gear nut, get a new cotter pin for that, it's a bit of work but it only took me about 4 hours to do, but I changed my track and spent some time cleaning everything. So probably a 2-3 hour job if you take your time like I did.

I was finally able to listen to your videos and there is no way that is just a brake rotor rattle.
You Definitely need to check inside your chaincase before you drive it much more.
I opened the chaincase up about two months ago when I changed the oil and didn't notice anything out of the ordinary. I didn't pull the chain or gears off just gave it a visual inspection. Didn't see any metal shavings or broken pieces. Any idea what may be loose in there?

Sounds like a bearing or something wobbling for sure.
I have also seen worn flatsided belts make some very strange noises some times seems like coming from chaincase side and make the brake rattle more.
Have you tried a new belt ?
Check your belt width and look for a skinny spots or lift the rear of the sled and run it with the clutch cover off and watch your secondary for violent wobble.

I've seen belts cause noises that I would have sworn was the chain or track skipping. Always inspect the belt or try another belt and go from there when trying to diagnose a driveline noise.

Would the belt noise sound when running the sled on a stand or does there need to be tension on the belt? I ran the sled on a stand and couldn't replicate the noise.

It doesn't surprise me that you couldn't duplicate the noise on a stand, there is nowhere near the load on the driveline. My advice would be to try a different belt and report back.
