Jack er up and check the old front end out first before you go spending money on something you might not need. I am doing my front drag link tie rod's right now, under warranty luckily. Could be a number of things from a worn out tie rod, ball joint, pitman arm, wheel bearing's, bushing's etc. Usually its a combination of stuff, which combined together gives it enough play to cause the death wobble. If you're unsure how to check, maybe a friend knows or an alignment shop is fairly cheap too. There are some definite nice upgrades like mentioned above but if your on a budget, it might be better to start with checking out the factory parts for wear and tear first.
