Scrambler chain issues and bearing replacement

[allwheeldrive]

As I get my Scrambler closer and closer to being 100% functional my latest challenge to tackle is the ever present “clicking / popping” of the chain on the left side of the vehicle when I encounter terrain resistance or immediately when I turn to the right AKA put the left side under heavy load. I tracked down the sound to the chain going to the back left tire. Upon inspection I found not 1 but 3 broken links. It amazes me that a chain can lose the sides of so many links and not break all together. Under the assumption the old chain was popping when the broken links went over the sprocket I replaced the chain. While the chain was off I ran the machine with 5 wheel drive. As I suspected the “clicking / popping was gone”. However with the new chain the problem is back exactly the same. I am assuming the old chain was broken from this popping. I now assume it must be the bearings. As there is no other culprit I could think of. I have the axle uninstalled, but would rather not have to remove the entire engine and break assembly to remove it from the tub. Is there any secrets to getting these bearings off? How do I even go about removing these inside bearings? Also if there is any Scrambler owners that have replaced these bearings if they have any advice or know the exact replacement numbers for say Buffalo bearings?

Thanks

Outside Bearing

Inside Bearing, how do I get it out of this little stamped housing?

You can carefully drive or press the bearing out of the housing as it is rubber mounted, it is however held on the axle with a snap ring.

inner bearing is easy to get off with a little puller. outer bearing... take hub off clean up shaft well. should slide off with long jaw puller or carefully cut it off with grinder but still have to clean up shaft to put new one on anyhow
