Default 4th gear grinding

Hey guys I have a 04 impreza rs with 175k on stock motor and trans. Clutch is 4 weeks old with new slave cylinder and clutch fork and all trans seals. I want some opinions and input. Every once in a while when I down shift from 5th to 4th it occasionally grinds a little bit. Doesn't happen every time but it happens enough that it's starting to annoy me. Doesn't grind down shifting into any other gear or when I up shift. I'm guessing the 4th-5th synchro ring is going out but I want to hear you guys thoughts. And if it is the synchro ring, is it worth it to replace it when the tranny has 175k on it? I would most likely replace other parts as well since I'm taking it all apart. Thanks for reading and I will take any and all replies to mind and decide from there.

Synchro. If you are replacing it, you'd want to replace the bearings throughout while you are in there. That probably all unless you see some other signs of wear or damage.
