I have a 1999 Tj and I am in the process of putting a Ford 8.8 in it to replace the Dana 35. What is the next step up for the front Dana 30? Should I stay with the Dana 30 and just put a locker in it. I am currently running 4:10's and 33X 12.5 tires. It is a 4.0 with auto trans. I do not do any rock crawling and primarily run mud besides it being my daily driver. Although I do have a 400 plus dual quad 350 sitting quietly under my work bench I have no intentions of replacing the 4.0 at this time. Any suggestions?
