I have a rear stud that is spinning in the axle. To replace the stud do I have to remove rear axle to get the old stud out ? I have rear disc brakes. Thanks for any help

 

amen brother would somebody please tell rkennan and myself cbliving how to take out the rear axle so we can replace the rear tire studs. Please?

 

Most of the time, axle removal is not necessary. If the stud is loose , you should be able to position the stud in a location to remove the stud without any special tools and install a replacement.
The replacement stud is drawn into position using a wheel nut turned backwards and the nut is tightened until the stud is fully seated.
