Replacing wheel studs
 

I need to replace the three inch studs on the front and rear of my 74 911 with stock size. What do I need to take apart?

Fronts and rears require removal of the calipers but only out of the way, use a coat hanger.

The rears require dismantling the e brake.

Mallet to punch ot the studs carefully or use a press

A sacrificial lud with top cut off to press new studs on or use a press

Caveat, once you do this your spare will require open lugs or you will destroy your very expensive lugs.

Thanks, Jim. I have a press, but the rears require removal of the entire control arm to use a press as the hub is pressed into the bearing or am I missing something?

On the fronts, can I remove the five smaller bolt to separate the rotor and then press out the studs?

One of the things I've done to install new studs without removing the hub is to get the stud in place then use a sacrificial wheel nut and spacers with an impact gun to pull the studs into place. I use one size larger nuts that just slip over the stud and stack two or three to leave 6 or 7 threads exposed. Then thread the wheel nut on, flipped backwards so the flat surface of the nut is against the spacers and the taper is facing outwards. I then use the impact gun to slowly and carefully pull the studs into place. Has worked well for me many times.

Pulling them in is fine, getting the old ones out is the trick I'm seeking.

Wow! In a stroke of brilliance I did a search on this topic. If you search and read some of the responses, you will figure out why I asked. There are some dangerous and completely unecessary approaches recommended. I'm going to use a cutoff wheet, clean them up and paint the ends. I figure that is the cheapest, fastest, and least risky approach. Thanks.

Ah ha, if you don't need them, yeap cut them off, Perfect solution, just be careful.

Yes, search is our best friend, brake a leg brother, just be very take good notes on ebrake dis-assembly.

The PO must have done a bearing change at the same time to remove the hub for install.

Cheers,

Thanks, Jim, pics to follow.
