Looking up previous comments, I see that I am not alone in my search
I believe that my bearings failed because of water entry, and that was because the seal did not fit properly on the axle, even though it fitted well in the hub. If the seal is fitted to the hub before a trial slip over the axle that problem might not be obvious. In my case the clearance between the seal and axle was about 1mm
I have been advised that this works: SKF 17624 (In metric units ID 44.45, OD 71.37, width 7.95 .... the axle measures 44.28, the hub 71.16. I've yet to receive them so will comment when fitted, if indeed they do. The apparently small clearance between the seal and axle is a concern but they are rubber and aren't all that round, so we'll see).
I add that my car is an '82 but it has a steering rack and I THINK that demanded new axles and hubs --- you'd need to be pretty keen on rack and pinion to change all that over and I'm grateful to the previous owner!
Those should be the correct seals
There isnt a need to change stub axles and hubs when a steering rack is fitted though...
