[DeTomaso] A ZF Type Question

[Forest Goodhart]

Chris,
You didn't say whether it is the nut turning on the stud or the entire stud 
turning. If it is the entire stud then I suggest removing it and using a 
helicoil or some such thread repair. If it is just the nut then you can just 
replace the stud and nut and be good to go.
Good luck.
Forest
