What's up all you Jeepsters. I've owned my 99 TJ for about 4 years now and I've finally decided to start upgrading it. I plan on getting some lockers first since I went to Uwharrie this past weekend and would've be able to do the toughest trail without being winched if I had them. My first question is what kind of axles do I have on my 99 TJ 4.0 Sport? I believe it's the 30 and 35, front and rear respectively. Also, what number spline do I have? What is a good locker to have? Like most people I'm on a budget and I don't have many skills as far as fabricating and welding. Thanks in advance.
