just for information on cost,
you always used to be able to get a PAIR of complete new front hubs with bearings fitted incuding postage, duty, VAT , etc are about £100-£120 but this from USA so it takes about 1-2 weeks to get them.
but below is an even better deal
these are probably even cheaper than above option about £50 for 2 complete hubs, i might get a pair of these for myself just as a spare pair.
