One of my front ones wouldn't budge so I got my mini gas blowtorch out and melted it out. Worked well!Finally got around to fitting my new cones, hi-lo's, knuckle joints and shocks in the rear. Everything came apart easily until I got to removing the old nylon cups from the radius arm, bloody thing will not budge! I've torn it nearly to shreds and it still won't move. I had to give up in the end, looks like I'm going to have to buy a dremel to get it out. So annoying that one little thing has turned a nice easy job into a hassle
I heard heat worked well and I was going to try using a little kitchen blowtorch but I was worried that it would melt onto the steel and it'd be even harder to remove. Bought a dremel today anyway but I might try heat first
