I started refurbishing my 4wd Cossie rear hubs last weekend, but the replacement bearings I've got don't fit.
Are there multiple types of bearing for lobro/disc braked Sierras, or are they all the same?
Bought the bearings months/years ago so too later to return. 
I bought some off the Bay a few months back and I seem to remeber they are different.
Not wanting to question your knowledge (of which I have no idea) but people have been known to forget to take the race bearings out as they can appear
to be part of the hub.
No offence taken! Definitely got the races off - which reminds me that the old bearing are taper roller bearings, whereas the (wrong) replacements I have are not.
hi ive looked at my recites and ive found some part numbers and i think that its BG2758 for the rear 4x4 cosworth bearings if no its DWB568 or DWB569 but i think thay are the 2WD front cosworth got mine from andrew pages cost £20 each and the fronts wear £10 each all + vat
