Solution...I had my original CV axles rebuilt. A few hours of my labor later...No more clunking!
I did compare the new axles I took off the Libby with my rebuilt OEMs. I did not check them before installing. They looked to be identical in length. I didn't check them before install, but if I did, I would have installed them. They looked to be acceptable to install.
With the unavailability of these axles at the moment, I would be leery of installing any aftermarket axles. I would highly recommend getting your OEM axles rebuilt. It cost me $70 per axle, which was about what the aftermarket axles cost. The only downside was the week it took to get them rebuilt.
Now my forehead can get a break from
