Looking for a stock rear sport axle with 3.45 gearing. 

Trying to pass my o2 sensor. Nothing else is working and dealer/ corporate are blaming the gears and tires. 

So plan is swap in a stock axle and some stock size tires. Make it their problem again

That's awful!! That seems like a lot of work that no one else has to do!  There has to be another solution.

3.45 gears?  That's a factory ratio?  

Just get any sport rear axle, and remove your front DL.  Then drive it around if that's a problem.

4.10 is Rubicon stock, so I never learned the other model ratios... Sorry.

I tried looking up a solution and came across your rant (I assume it was you) on the JL forum with the guy with the crazy drive cycle. Hopefully you can get it resolved. I use the smog place next to the Quick Quack car wash on Blue Ravine and Prairie City.  My TJ is temperamental but they get it smogged after a couple of tries.
