Replacing rear axle wheel hub on 2014 Gs 350 f. I dont have the usual bolts that hold the hub, anyone know how to remove?

 

OK, that looks like the inside of the rotor/drum side of the hub and judging by the parking brake shoes, I'd say a rear one. The bolts are Allen-hex bolts that come out from the back. There are 4 of them and it takes some effort on a few of them. I did a thread on replacing this bearing recently. You will need to be very careful with the dust shield and the ABS/speed sensor that fits into the knuckle and the dust shield.
