Weird problem with rear axle. (Video Included)

*Update in Post 6*

I am not too sure what the problem is here. I was driving the ATV yesterday for 5 Hours with no problems cleaned it and put it away. I go to take it out today and as I drive down the street I notice the quad has a bad shake in the rear end. I get off and check all of the tires and lug nuts everything there checks out fine. I tightened the chain and that did nothing. The bike is a 04 Z400 with a few performance mods. The only work done to the quad recently was I had the stator replaced because the screws backed out and shredded the old one to pieces. please watch the videos below and if anyone has an idea please let me know.

*Click images to play the video*

The first video is me spinning the tires by hand. Notices the quad develops a strong resistance and eventually becomes very tough to turn.


Second two are just the bike running in 1st gear with the tires off the ground.




Thank You

Check the hubs and bearings. Put the rear up on jacks and run it in gear. Watch for wheel wobble or bent axle, or at least listen for where the noise is coming from.

I have never replaced the rear bearing and Im not sure if the previous owner did. When I life the rear tires off the ground and spin them I do not notice the axle being bent and the rims look fine. it looks like the rear sprocket is bent slightly and I notice as I spin the tires by hand the chain will slowly tighten up until it is so tight the wheels wont spin anymore.

Probably have a stretched chain, bent sprocket, bad roller, or all 3. Take the chain off and try to roll it.

I removed the rear sprocket and the bike still had strong resistance when rolling. I noticed the metal was rubbing on the top of the rear axle bearing carrier.




do you guys think it is just out of alignment somehow or do I need to replace the entire rear axle bearing carrier. I already ordered a new chain along with new front and rear sprockets.

I ordered the bearings today.

All Balls Rear Axle Bearing Kit | ATV | Rocky Mountain ATV/MC

that is what I ordered. I have no problem putting them in myself and hope to be back on the trail on Monday.

*Update*

Well after fighting with the rear axle nut which wouldn't budge no matter what I did I finally got it off. right away I could see the bearings were beyond bad and there was a large amount of dirt and rust in the housing. I was unable to remove the axle from the carrier so once I removed all the bolts and slid out the whole carrier it was clear things have been bad for awhile. The weird thing is the bike just started shaking a few days ago so I am surprised it drove ok with all this going on inside.





I will replace everything and hopefully it will drive like new.
