Body Flex... How much?

[elks]

So I have been running a soft top since I got my Blazer like 5 years ago. Every since I bought the blazer I noticed it has some body flex. Enough to feel the seats shift in twist, Door get stuck when twisted etc.

Does your blazers body flex when twistet upP If so enough to cause a door to stick?

If not why does mine? Frame seems solid and everything. I do have a small crack near power steering box, but other than that it all seems solid? It almost feel like the flex in a unibody Cherokee(not quite as bad)..

If my body is flexing will it cause hard top issues or will the hard top help fix the issue?
