I'm looking to Fozzy lock front and rear axle on my YJ. I have an 8.8 rear with an open diff, and a D30 front. I think I have the 297 U joints on the front shafts since it's a 95 model. I have wheeled open diffs for over 2 years now, and finally ran across this type of cheapo locker while searching. Any suggestions or ideas about this type of welded diff. I've read some postivie feedback but it was from zuki guys. I'd rather hear the real deal.
