I've thought about putting an Aussie in the front of my XJ, but I have to wait a little while longer for other repairs and things to be done first. Everything I've read has been good about the Aussie. I have a couple friends with them and they love them even in the front of their Jeeps. In 2wd you shouldn't notice them at all, but in 4wd steering will be a little more difficult and your TJ will want to go straight in the snow rather than turning. My friends drive all winter long without problems, but it takes some time to get used to.
