I put a post up the other day "Year old hub knackered" regarding Paddocks OEM hubs. I had to eat a large slice of humble pie, as the hub was not knackered at all. So based on that, I would recommend Paddocks. OEM hub is now £145 + vat. I have since replaced the offending hub (not the one i thought it was) with another from Paddocks.
You can get them now for £50 new on ebay as for quality.
So far so good time will tell.
No probs in fitting as long as you have a 3/4 knuckle bar
As the hub nut is very tight and I have previously broke a 1/2 knuckle bar.
Ribble Valley 4x4 do them for £48 with 12 month warranty. LR Trade Parts do them for about £60, again with 12 month warranty, although theirs comes with a new O-ring (for rear hubs) and new hub bolts (fronts are long than rears - I got sent the wrong set, but kept them anyway and just re-used the old bolts).
I think there's new stake nuts included from either source.
