M5970DT front dual trans wheel issue

[Buzzelec]

for obvious reasons I need to remove and replace this ball race. Assuming the bottom king pin nut will require removal?
Thanks

You need to remove the entire drive assembly from the axle housing. Then you will have access to remove the bearing.

FYI: DT means Dual Traction (4wd) not dual trans.
Are you 100% sure on the model number?
I know your in OZ but I don't find that model #.
EDIT: Correction I did find that model it's just rather rare.
