I have to say I did mine without any great struggles, with the special tools of course.
I had a front replaced about 15 years ago, Omicron wouldn't give a price as it depended how the job went, mine involved a lot of hard work and a gas torch to heat things up, as after 40+ years it didn't want to come off.
All the work was carried out with the hub on the car.
It took a long time and the cost reflected the time involved, + the cost of the bearing which was over £100 then!
It's an enormous bearing and make a good door stop, so not surprised they last 40 to 50.
years.
