Dreaded clunk when turning

OK I see a bearing seal there in the end of the tube on that 7 1/4 rear axle.

I am thinking there is a roller bearing just inside that seal. You need to reach in through the seal feel if that roller bearing has grease on it or if it gets lubed from the gear lube coming from the pumpkin.

Thinking it is gear lubed on the 7 1/4s.

The 8 3/4s are grease packed on those.

If it is gear lube just pour a little more lube in through the seal on to the roller bearing. Then stick the axle back in.
