Problem overview

Some Jaguar XJ8 owners report experiencing issues with broken lug nuts, often due to over-torquing and seizing. This can lead to fragile studs and alignment problems within the vehicle. Additionally, excessive pressure during removal may cause the crimped chrome hex part of the nut to detach from its main body. It is crucial for owners to adhere to the correct torque specifications when tightening lug nuts to prevent potential damage. Furthermore, using the wrong size or type of lug nuts can result in improper fitment and pose safety hazards. When dealing with a broken lug nut, some owners find that applying a low viscosity penetrating oil can assist in loosening the nut for removal. These concerns underscore the importance of proper torque application and maintenance practices for the Jaguar XJ8.
