Baja rear wheel bearings?

I've got snapping and popping from the sprocket side wheel bearings on my 990 Baja. I assume the bearing is failing. At 3900 miles, does anyone know if this is warranty worthy?
Local dealer is closed on Mondays. Thanks.

Possibility, I have never touched it since new. I thought it would have loosened up over time. Always looked OK.

Maybe chain is loose. Highly doubt it's the bearings but if it is then it's likely warranty. Unless your 3*00 miles were actually in baja...

Any chance the popping is coming from the chain guide?

I spent quite a bit of time with it last night. The chain is now over lubed and clear of hitting anything. I guess what has me puzzled is that it pops hard enough to make the spokes ring. This happens every half to three quarters of a turn. I've been around a lot of failed/failing bearings and this doesn't have any of the roughness or growling one would expect. I'll pull it apart as soon as I can and post up what I find.

Thanks everyone for looking.

My 2011 990 bearing failed on the rear {brake side} at about 3500 mi.
froze to the axle. It was warranty they replaced bearings and axle.
The part that sucked was I was about 20mi. from home and rode
the bike had no choice.

OK. I took a deep breath and had a careful look it.

It appears it is the cush drive carrier bearing. I think that is why the wheel turned smoothly but the the sprocket was ringing. Holding the wheel up by the axle, the cush drive bearing catches and is a little rough when spun slowly. Running the wheel bearings with my finger, they feel just fine. I'll explore this with the dealer tomorrow and let you all know how it turns out.

That's the sounds my 640 Adv made when the bearings were bad. I pretty sure your warranty won't cover wheel bearings.

Mine does that ever since (40k km). It's some mess getting beneath that aluminum cover which covers the bearings.

I cleaned things up to try to ride it to the dealer (approx 100 mi.) In the process I found that the Inner cush drive bearing was the one that was crapped. The outer cush drive bearing is a bit rough. The actual wheel bearings 'feel' OK. The cush drive bearings also polished the axle and even felt like they were wearing gooves. At this point I chose not to take the bike but only took the wheel assembly. So far the dealer is treating this as warranty without a lot of questions. Even talked them into the SPROX rear sprocket I was supposed to get with the bike. So far so good.

Problem covered, but...

I don't want this sent to the basement or to bash my dealer, so without mentioning any names. My local dealer was completely ball-less when dealing with KTM. It seems KTM did not want to cover the failed bearing at first. The dealer called and said pick up your wheel, no problem, no charge, all is good! I call KTM customer service again and explained carefully that the sprocket carrier bearing is failing, the spacers were spinning on the axle and the axle was grooved beacuse of it. They said they would get back to me.. . . . .
They never did. The dealer calls a couple of days later and asks if I can get the whole bike down to them. I assume KTM called them and said they would warranty the problem. I guess I'm OK that they repaired it, but it did take the entire month of June. Summers are short here.

On a different rant, the bike did not come with the advertised Supersprox sprocket. I mentioned a couple of time while in the dealer over the past while. They didn't seem too interested. I pressed the case while getting the wheel issue sorted out. The dealer told me that it would do them no good to ask for the sprocket but for me to do it. Another WTF moment. I did and KTM was better on this. They said to have the dealer fill out a mising parts claim. KTM would sent the part and the dealer would install it. How hard was that? I now have my pretty orange sprocket!

Maybe I'm a whiny little bitch but just to let others know that if your problem is real, stick with it. You will learn if there is service behind the smile in the showroom. KTM seems willing to do the right thing if you pursue it. And yes, for a hundred dollars worth of parts and and an hour of shop time I could have been riding three weeks ago. It just didn't seem right though.

Back to ride this week-end.
