I'm replacing the front swivel bushes, bearing, oil seals etc on my series 3 109. I've rebuilt the swivels and looking to fit new half shaft bearings Looking at the Britpart bearings (secured with a flimsy plastic roller holder) compared to the old ones (held securely in place with brass keep)...

Can I ask what is the best way to remove and refit the front axle oil seal? See pic below. I'm replacing the swivels on my 1973 109" SW and I'm struggling to get the seal out. Any advice very much appreciated. Graham
