Okay, I've been reading all the threads on gearing and I just don't get it.... Maybe most people think automatic transmission, but my XJ is a standard and I'm not going to change that (although I may upgrade to an AX-15 at some point). Here's my stupid logic so someone can explain where I’m going wrong.
First of all, this will be a toy for running around town and to the beach with the dogs. No serious rock climbing or trail riding planned. If that changes, then I'll rethink the tire size and gear ratio thing.
My 89 4.0/BA-10 XJ came from the factory with 3.07 gears. Now, I'm going to assume that my XJ came with 28" tires and the engineers that picked the 3.07 factory gears knew what they were doing. I have a donor 89 XJ 4.0/AW4 with 3.55 gears. The plan was to put these axles on my XJ.
The way I figure the math, I can run 32's and still be very close to the original design gear ratio. According to the posts I've read here, 3.55 gears are way off.... So where am I going wrong?
Thanks for the help.
