If have you have never done any maintenance to your carrier, you better now before you wind up with a siezed carrier in thew swingarm or siezed axle in carrier or siezed brake hub and axle nuts.
I would remove everything, replace the carrier bearings (as in most cases you get maybe 5 years of reliable service with light riding on good OEM or aftermarket bearings) clean everything, and reassemble with waterproof silicone paste to keep everything from siezing. If you don't, then you will be posting how to remove siezed axles from carriers in a few years. Search crazy 70 man's posts. He just ran into these problems and it is very common on neglected 250R's. Also a good time to do your swingarm bearings and bolt. 9-10 times they are siezed in the swinger.
Here is where my long useless list of stuff nobody cares about should go...
