You really need to read up on this, to avoid any frustration or expensive mistakes. There's a ton of info on jerry's site, lotus-europa central.
On one of my hubs, it came apart easily, the other, well I broke two pullers in the attempt. Finally got it with an acetylene torch with a third puller in place. A real wooly-booger, for sure. Frankly, I don't think that particular hub NEEDED a nut or safety washer!
In my case, a heat gun, or propane torch did not suffice. Your results may vary.
I had to heat it, until the locktite bubbled up from around the splines before it released.
Please avoid the feeling you can pound this out with a hammer. The uprights are fragile, and are hard to come by.
