I'm not saying it can't be done, I would however advise that without the proper tools you will be extremely lucky to get it right. The cost to replace a pair of prematurely worn tires will more than offset the cost of a front end alignment. It also is most certain there is a steering or suspension issue in that the pop when cranking the wheel and sudden & bad change in toe should not happen. Steering should be considered as one, if not THE most important thing on the car from a safety standpoint.
Please reconsider doing this at home.
