My tub has a pop-up trip lever drain like this:
My tub is clogged; the water drains but very slowly. I tried to use an auger to clean it out but can't get past the spring.
How do I disassemble the pop-up trip lever drain so I can remove the clog?

My pop-up sink drain had a similar problem. I finally figured out that the top screws off the stem like the cap of a mushroom. I had to show it who's boss and that I meant business, but it finally unscrewed and I was able to clean the drain.
You may also find that if you take the handle out, the spring is clogged with hair (that used to happen to me as well.)
I would save time and get a drain opener. Crystal Heat is actually crystalized Sodium Hydroxide and Sodium Nitrate (dry). You can't use this when there is standing water. Pour about 1/4 cup down the drain and add a small amount of water. This stuff will boil and heat up to a point that it will actually melt grease and soap scum. It will also burn out hair clogs.
