Case 580K backhoe driveshaft/transaxle question

I am looking at a 1990 Case 580K, 2WD backhoe to buy.

I crawled underneath to check out what I could. I grabbed the driveshaft and found there was some movement at the junction of the transaxle. It is not the universal joint. That is tight.

Is this something that is serious? If there is a splined shaft that is sticking out of the transaxle, then it is a "collar" that is worn, not a bearing out in the transaxle, right?

Thanks.

Jim
