Send in your half shafts to have rebuilt. Units are disassembled, completely stripped of any coatings and inspected for trueness and straightness. Yokes are inspected for any overly worn areas, failure points, and c-clip area for proper remounting of u-joints. Highly quality non-greaseable u-joints are used for strength and keeping the underside of your Corvette cleaner (greaseable units are knock for flinging grease).
