Although you say you've stripped the bike to check frame damage and couldn't find it, weakening isn't impossible even if it can't be seen (by the sounds of it, your bike took a fair thump), so it may be an idea to get it double checked (it won't need much of a twist in it to feel totally different).
You mention brake disc wobble - were the discs running true beforehand?
