Replaced the cv axles today in my 07 classic. Job went smooth until I got everything back together and went to double check I torqued everything and noticed that the hub end of the cv axles are different not the passenger side vs the drivers side. I didn't notice it when I installed them since everything went so smoothly. I'm wondering if there was a design chance at some point and one axle was manufactured at a different time then the other? I got them from napa and the part numbers are the same on both. It was too late to call them by the time I was done but the part number I got was the only number listed for that year and body style truck. The top picture of the cv matches the factory one I removed and the second one is the odd ball. Seems to drive fine but haven't put it in four wheel till I figure out if it's a problem. Has anyone run across this, or have any idea why they might be different?
