So I fitted the new front hubs last night, was a pretty straight forward process as I already had the wheels and brakes off the car. I was not able to find much info here on FG front hubs/bearings so I'll post up some pictures for anyone who may be interested or have the same issues. Remove wheel, unbolt caliper from spindle and put to the side, remove brake rotor from hub and you are left with this. Remove the ABS sensor from rear of hub held in by single torx screw, remove the 3 15mm bolts that hold the hub to spindle and after a clean it should look something like the pic below. Removing the hub bolts was pretty easy with a 40cm breaker bar and deep 15mm socket, just needed to turn the wheel to give room to get to the bolts. The old and new hubs side by side. Replacement hubs are Repco part number RWH6130. New hub fitted up. I torqued the bolts up to 126Nm as per the suspension spec sheet linked in first post. Was a bit tricky getting a 50cm torque wrench in the wheel arch (doing it on garage floor) but enough room to tighten the bolts but turning the wheel which allowed access to all 3 bolts. As soon as I pulled out of the driveway and drove down the road there was less noise from the front even in a straight line, turned left at the end of my street and whisper quiet. Few laps around the block and all is good. Drive to work this morning the doing 100km/h on fwy and the car is defiantly a bit quieter so the old bearings would have been contributing to what I thought was all tyre noise. As couple of comparison videos.
