Vertical connections/Hubs: early vs later

Vertical connections/Hubs: early vs later
Hey there,
while I'm giving my suspension a thorough workover, I've come accross the differences in wheel bearings due to different hubs. I am aware of the difference in hubs or better said in the uprights/vertical connections. But were they better?
Reason I am asking is simple: I always keep on experiencing warped discs/rotors. The discs though aren't warped but they act like it. So my guess is the bearings are toast which I would put down to the old style smaller bearings just not being as durable as they could be...
Is it worth upgrading to the larger wheel bearing hubs? I'm going 325 mm brakes in the front and also need wheel bearings and will be having the entire axle apart...
Cheers
Damien

You post doesn't tell us what you are working on, but I encountered the same problem on my XK8 1997 when doing the front wheel bearing. The larger bearing came on the updated hub. The problem is on early models the left and right hubs are identical and on the later model the hubs are specific to each side. They also changed the mounting points and changed the location of the caliper mount.
As such I had to stay with the hub I had and replace the bearing in lieu of replacing the vertical mount. The earlier used the smaller diameter wheel bearing. The difference in size is so small I don't think it makes one better than the other.

Is it possible that you have uneven brake pad deposition on the discs? If you've measured the discs to ensure that they aren't physically warped, but they still behave as if they're warped (judder or pulsation during braking), you might have slightly more brake pad material transferred onto only certain parts of the disc, causing the pulsation.

Discs and pads were always driven/bedded in. It has happend on several different pads and discs.
Calipers work both perfectly. No binding or sticking...
