Yes,, but then you diss-regarded the post to try and twist the axle slightly to engage the spline,, and then RRR explanation of loosening the carrier bolts to re-align the splines.. and a coupla others tried too..
Oh well,, re-read everything,, and your next path should be fairly clear..
We're all pulling for you like you wouldn't believe, (except maybe one.. lol)...
Ha ha! I can miss the forest through the trees sometimes. I don't think I understood at the time about twisting the axle to force it to line up the splines. Believe me. I understand now! Sometimes I miss Chevy's. A lot less confusing.
