It's a good bolt and stuff

Haynes prescribes replacing these every time they are removed, due to angle-tightening after torquing. Be aware that one is included in the following kits, so you don't need to order this separate item: The CV Joint Boot Kit (Genuine Volvo; no photo on website); and The Lemforder Ball Joint (see photo). I did not buy the Genuine Volvo Ball Joint but its photo indicates that the axle bolt is also provided.
