The rebuildable steering drop arm isn't too bad a joh if you can get the drop arm off. Doing it on the car is much harder.
If the fixed race isn't too badly worn you can hammer it out with e drift (cheap screwdriver) but if it's badl worn like the first one I did then you have to grind 2 cutouts with e Drenmel to allow you to see the shoulder of the race.
I like to polish the ball and races with very fine wet and dry, this makes them last longer. Rebuild with lots of grease.
I use a G clamp and 2 sockets to push it all together, if it's not hard then you've left a bit out, my favourite being the O ring seal :roll:
