Question about the 7 1/4 rear end.

Just wondering if it would be a good idea to replace them. No noise, just unknown mileage. Ring gear looks great.

No noise?

Fill it back up and leave it alone.
But if you would like to start with a fresh stronger setup, I have a ready to go 7 1/4 sure grip I'd sell you.
