Wobble usually only from the two things that directly affect toe: steering and lower (rear) control arm. Upper bearing is a regular cause of the clunks but I've not seen them make wobble but there's always a first time but eliminate the easy ones to test.

My last wobble that was the steering gear would wobble at certain curves in the road so see if you can find a magic curve where you get a wobble.
