Ok i was tradind suspension on my 92 honda with another 92 honda and the axle popped out of place and we got in back in place but when i go in first it just revs really high as if its in neutral i put the axle back in the tranny
Compare both axles replacement and original side by side. You may have a limited slip axle and a regular axle.
the axle clip is off in the differental sounds like. That axle popped out for a reason maybe the splines are not hooking into the transaxle like they should.
That axle is not engaging the axle gear in the tranny. Pull it out and put it back in. It should go in all the way to the cv joint. If that doesn't work, the axle gear is broken and the tranny will need to be removed and disassembled to replace it.
