They are both D35 rear axle's? Why won't the gears work then? It's the front that wouldn't work since the YJ is reverse cut and the TJ is standard cut.
The only difference between those two axles are the spring perch/ TJ hardware, and maybe ABS (if either had it)
In that case, not much of anything is useful. They use different just about everything in them. Sorry can't be more helpful, maybe someone else can chime in and teach us both something new. [img]/wwwthreads_images/icons/wink.gif[/img]
