Hi, i have a 1999 mxz 600 and when it gets in deep snow and i crank on it theres a pretty severe rumble somewhere, i've checked the track tension and its fine, also i have checked the chain tension and that is also fine, the belt doesnt have and flat spots on it either, so if any of you can help me out with this that would be great because this has been bothering me for a long time. Thanks

How many miles on the sled? How long has it been making this noise?
Have you ever serviced the gear case?

There are about 4500 miles on my sled and it has been making this noise for the last 1500 miles. Yes, i have serviced the chain case that was the first place i looked. The chain caise oil was replaced, i tightened the chain, and made sure everything was snug. Any idea of where else i could look for the problem?

Check the bearing on the other end of the drive shaft.
When that bearing goes, many times the only indication is that the speedo no longer works.

Driveshaft/jackshaft bearings, like RJ said.
