Actually, I'm pretty sure they are one-time use since they're an aluminum alloy. If you have the older T27 head bolts, they tend to strip easily during removal which is why ZF later replaced them with larger head T40 bolts. If you have T40 bolts, a lot of people buy a few "just in case" and don't replace them since they're pretty pricey. The key is to carefully torque them to the correct specifications (believe it's only 6 ft/lbs but you should double-check to be sure).
