Leaking shower diverter valve

Have a leak on a shower diverter valve which is the center valve on a 3 valve manifold. It doesnít leak when water goes to the tub, only when redirected to the shower head. It appears to be coming from behind the second / rear larger brass nut. Should that be removed?

I see your arrow. I don't see any water.
What are you pointing to..... a crack in the valve casting or the threaded nut ?

The water was off for the picture but was leaking behind the second larger nut. I removed the smaller front one and was able to remove the diverter shaft. Wondering if that back larger nut was meant to be removed or if it is part of the manifold. Itís at my sons house and I didnít have the tools I needed so Iíll be headed back over tomorrow. Thanks for any and all input.

It's hard to tell if that rear hex is a removable nut or on the casting itself.
I wouldn't expect that to be a removable nut as the guts come out with the front nut.

If you try to loosen it.... go gently.

Get a bright flashlight and look inside and outside for any signs of cracking. Look especially close if the house froze during the historic power outage Texas went through.

If the body is cracked, what is on the back side of the faucet's wall? It's not a bad job to cut an access hole in the sheetrock on the back side to replace the faucet. Then make a simple access cover for the hole or patch the sheetrock.
