Can I replace the tone ring on a 2006 without replacing the half shaft axle
You can. Most shops will just replace the half shaft because it's easier and less of chance of cracking the new one and labor removing the old one, because most rust on there.
Don't forget the Warranty! It's a CYA move for the shop but a new or Remanufactured half-shaft has a warranty that covers the entire half shaft - just in case the old one has a concern that only becomes evident after being disturbed.
I just had a second tone plate replaced for a mere 458 dollars.what a deal.only two to go.
