Kubota M5700 front axle oil seal replacement

[unnet]

I have a leaky front wheel oil seal on my M5700. There are a few videos on youtube of similar repairs but all from smaller tractors/fewer parts. Do any of you have a video of replacing an M5700 seal? Those bolts haven't been off in 20 years. I'm afraid to pound any harder and I'm not sure about which bolts I need to remove- specifically the ones that hold the top zirk fitting on? The service manual doesn't tell me much. Any help is appreciated. Thanks
