Not surprised. I figure there's not really another option for half-shaft issues. Did they say it was the inner CV joint?
It's really not a major issue, pretty sure just a few things on the front hub have to be removed (if necessary to allow you the space) to remove the half-shaft, and then it just pulls out and they put another one in. Just plops right into the differential. Maybe they replace seals too but I'm not sure that's necessary (I never have when replacing half-axles). It's really a super easy job - the main issue is simply making sure you have the space to work to remove and replace the axle.
I sure hope mine hold together for my 1200-mile drive.
Did yours sound similar to the video I posted (above somewhere)?
