2020 TM 2720 Grease Bearings Question

[live4fun]

I have the newer wheel style as shown and have been trying to see if I can grease the bearings without removing the wheel. So far I haven’t been able to remove the dust cap and it appears that I’ll have to remove the lugs and wheel to get behind the cap. Or my second option is to have my service guy grease the bearings and check/adjust the brakes. Has anyone had experience with this style wheel and bearings set before I remove it. Let me know. Thanks
